High Performance Fuse For Automotive Applications
• Very high rated current up to 50 A
• Safely interrupting 1000 VDC
• Versatile mounting options

With the AEO 10.3x38, SCHURTER launches a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the cartridge fuse, which requires a fuse clip (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Applications Automotive:
DC/DC Converter, On Board Charger, Battery Management System, PTC-Heater and Houshold Charging Stations.

Chip Fuse for Highest Demands
* Pulse- and temperature-resistant non-aging chip fuse
* Sealed against potting compound
* Meets requirements according to AECQ

With the UAI 1206, Schurter offers a pulse and temperature resistant chip fuse with time-lag characteristics for applications where durability and maximum reliability are requested.

Conventional fuses have a sort of memory. If they are exposed to pulse-shaped current peaks and high temperature fluctuations, their properties change. Every pulse makes the fuse a little weaker, every temperature fluctuation a little more susceptible. Not so with the Schurter UAI 1206.

Pulse and Temperature Resistance
Because of the a special fuse construction, dubbed by SCHURTER as “trace in air” technology, the UAI’s ability to resist current pulses smaller than the melting integral (I2t) is thereby increased exponentially. Comparably, the UAI 1206 has practically no derating to the usual extent. The ingenious design of the fuse body also dampens temperature fluctuations to a high degree. The SCHURTER UAI 1206 is also hermetically sealed against potting compound for use in intrinsically safe applications.

Areas of Application
The new chip fuse, which is offered in two versions with rated currents of 5.3 A and 7.5 A, was specificially developed for automotive applications. The Schurter UAI 1206 meets all requirements according to AEC-Q200. It is also suitable wherever high levels of pulse currents, high thermal fluctuations, and high mechanical loads are present.

Compact protection for 3-phase systems
* High rated voltages of up to 500 VAC / VDC
* High breaking capacity of up to 1500 A
* Also available as pigtail version (from 1A)

Schurter extends the range of rated currents in the compact high-performance fuse SHF 6.3x32 down to 500mA. The SHF 6.3x32 is a ceramic fuse for higher voltages (AC and DC) with fast tripping characteristics. The high dielectric strength and the high breaking capacity of 1500 A opens up new fields of application.

Schurter now offers the SHF 6.3x32 in nineteen rated currents between 500 mA and 32 A. The high breaking capacity of 1500 A at a rated voltage of up to 500 VAC/VDC characterizes the fuse. Besides a multitude of applications in the energy and industrial sector, the SHF 6.3x32 is especially suitable for the protection of 3-phase systems.

The SHF 6.3x32 is available as a fuse link and a pigtail version (from 1 to 8 A). Fuse links are suitable for mounting in clips and fuseholders, which makes it possible to quickly replace the fuse. SCHURTER therefore offers an extensive range of clips and fuseholders. The pigtail version allows direct mounting on printed circuit boards using THT soldering technology.

The SHF 6.3x32 can be used as RoHS-compliant fuse for lead-free systems. The compatibility with competitor products allows SCHURTER to offer the SHF 6.3x32 as a replacement product. The fuse is approved by cURus.

* Very high melting integral (I2t)
* Variants up to 50 A (Pigtail)
* Clip and Pigtail versions
* Excellent price-performance ratio

With the SUT-H, Schurter introduces a new 6.3x32 mm ceramic fuse for single-phase applications for high rated currents from 10 A to 50 A. Thanks to a particularly high melting integral, it is particularly suitable for applications where high inrush currents occur.

The new Schurter SUT-H is technically based on the proven SUT. In contrast to the known fuse, the SUT-H has a much higher melting integral, which makes it particularly pulse resistant. High inrush currents, which occur in power supply units, are easily absorbable.

The fuse is offered for direct mounting on the PCB with pigtails or with a solid beryllium-copper clip (Schurter CQP), which allows an easy replacement of the fuse without soldering. The clip can be up to a rated current of 10 A.

The new 6.3x32 mm SUT-H ceramic fuse opens up completely new areas of application by extending the rated current range up to 50 A and opens completely new areas for innovative applications.

The fuse meets the requirements of the UL 248-14 standard, is cURus approved and RoHS compliant. The SUT-H is developed and manufactured by Chi Lick SCHURTER in China.

* No tin whiskers, no tin dendrites
* Lead-free coating (RoHS conform)
* Similar fuse qualification as in MIL-PRF 23419
* Hermetically sealed and robust construction

Schurter extends its successful MGA / MGA-S line of 1206 dimension SMD ceramic fuses with an aviation version that is tin whisker free and completely dispenses with leaded coating.

Crystalline tin dendrites and tin whiskers pose a considerable risk of short circuits in highly dense electronics. Dendrites form during the electro-deposition process, whereby heavy marks could appear on the fuse end caps or housing. A thorough inspection and cleaning is required according to MIL-PRF 23419. Tin whiskers form after the electro-deposition process. The cause is not well understood, although adding lead to otherwise pure tin soldering is commonly used as a preventable measure.

However, lead has become an unwanted element according to many environmental initiatives, e.g. RoHS directives. For this reason, Schurter has extended the successful SMD thin-film fuse family MGA with the new –A variant. In addition to the classic MGA and the ESA-certified MGA-S space fuse, the aviation version, MGA-A, uses gold alternatively to lead. Gold plated end caps provide a surface where neither whiskers nor dendrites can form. This makes the new MGA-A a safe solution for use in not only highly sensitive electronics in the aviation industry but often suffices for use in the industrial grade space sector.

The technical design is similar to that of the ESA-certified MGA-S. This means: hermetically sealed, ultra-robust construction, which is ideally suited for use in intrinsically safe applications according to ATEX and IECEx requirements. Despite its very small footprint (1206), the MGA-A has a particularly high breaking capacity of up to 300 A at 125 VDC and can be used in a wide temperature range of -55 °C to +125 °C.

The new MGA-A from Schurter is suitable for all applications where the highest demands are placed on reliability and availability.

The new fuse holder standard IEC/EN 60127-6 Edition 2, requiring increased glow wire resistance, will come into effect the beginning of October 2017. Schurter is ready!

With the updated fuse holder standard IEC / EN 60127-6 Edition 2, more attention is given to the area of fire protection. New requirements focus on the materials being used, which must be glow wire tested according to IEC / EN 60695-2-12 and -13 (GWIT=775°C and GWFI=850°C).

These new requirements are contained in the standard for household appliances IEC/EN 60335-1, which has been a long time established standard, particularly due to the prevalence of such unattended appliances (e.g., coffee machines).

All manufacturers of fuse holders must therefore check the glow wire resistance of the materials being used and, if necessary, replace the material. It is also necessary to update the approvals and to carry out a re-examination by the certification body. In case of a material change, the tests according to UL 4248.1 must also be repeated.

All fuse holders certified Until October 08 2017, SCHURTER will have adapted the complete range of its IEC-certified fuse holders to the new standard, including power entry modules with fuse holders. This will poise SCHURTER as the first manufacturer of fuse holders ready to meet the stringent standard.

All Schurter IEC-certified fuse holders marketed as of October 08 2017 will comply with IEC/EN 60127-6 Edition 2, as well as UL 4248.1, and can therefore be safely installed in all household appliances.

Customer-friendly Schurter has placed great attention on the fact that the same part numbers will be used. This makes it unnecessary for the user to make changes to a parts lists, or be deal with new approvals.

General Rules from VDE
-  The manufacturer will lose VDE approval after October 08 2017 for any parts that do not conform with the new requirements for IEC / EN 60127-6 Edition 2 and therefore must no longer sell those products.

-  All parts the manufacturer already sold to market (i.e. to end-customers, distributors or resellers) before October 08 2017 maintain valid VDE approval.

-  All mixed inventory at end-customers, distributors or resellers can continue to be used or shipped or resold without any limitation.
