DSTH DIP Switch
DSTH DIP Switch: Robust Standard Profile and 2.54mm Pitch THT (through-hole technology) Switch
The DSTH DIP Switch is a robust, standard-profile and 2.54 mm pitch THT (through-hole
technology) switch. It enables electronic devices to be configured directly at hardware level. Addresses, communication parameters, logic states and operating modes can be set easily and
clearly, without modifying software or firmware.
Electrically, the DSTH uses SPST contacts and offers 2~10, 12 multiply positions. Ratings are 25 mA at
24 V for frequently changing switching states and 100 mA at 50 V for constant switching states. Initial
contact resistance is ≤ 50 mΩ and ≤ 100 mΩ after the specified tests. Further specifications include a
dielectric strength of 500 V AC for one minute, 2,000 mechanical switching cycles and an operating force
of ≤ 8 N. The operating temperature range extends from -40 °C to +85 °C.
Typical applications include PLC controls, industrial servers, medical devices, robotics, air-conditioning
systems and household appliances. In these applications, the DSTH can be used for RS485 and
Modbus addressing, BIOS/CMOS settings, as well as the configuration of hardware parameters,
functions and operating modes. Combining proven performance, competitive cost and fast availability,
DSTH is an ideal solution for OEMs seeking a reliable alternative to premium-priced standard DIP switch
brands.

With the new 4763 Type F/J outlet, Schurter offers a flexible solution for modern power
distribution systems.
Appliance Outlet 4763 IEC Type F / J
With the new 4763 Type F/J outlet, Schurter offers a flexible solution for modern power distribution systems, particularly in data centers. By combining Type F and Type J in a single outlet, the 4763 supports different current ratings while simplifying the design of intelligent PDUs.
A key advantage is its full mechanical compatibility with existing Type J outlets such as the Schurter
4797-5. Identical cut-out dimensions allow existing designs to be reused without modifications to front
panels or PCB layouts, reducing development effort and simplifying retrofits.
For maximum design flexibility, the outlet is available with optional light guides for status indication and
various configurations to accommodate different panel thicknesses. It supports PCB mounting, operates
reliably from –25 °C to +70 °C, and complies with relevant TÜV requirements.
Additionally, the 4763 supports established cord retention systems such as V-Lock, P-Lock, and TwyLock,
ensuring secure connections in critical applications.
This makes the new Schurter 4763 an ideal choice for data center, industrial, IT and
telecommunications applications where flexibility, reliability and easy integration are essential.

Schurter Three-Terminal Fuses (STTP) for Battery Systems
Intelligent Fuse Solutions for Battery Systems
The Schurter three-terminal fuses STTP 9550 combine conventional overcurrent protection with an actively triggered overcharge protection function, providing an additional layer of safety for lithium-ion battery systems.
In addition to current-dependent interruption, the integrated trigger terminal enables controlled activation in critical operating conditions. This allows reliable disconnection of charge and discharge paths even in the event of protection IC or FET failure.
Gold-plated terminals ensure low and stable contact resistance, high signal integrity, and
excellent corrosion resistance. The compact package supports high-power-density battery pack
designs ranging from 1 to 24 cells.
Applications:
Typical applications include energy storage systems, power tools, UPS equipment, e-bikes, e
scooters, and automated guided vehicles (AGVs). Supported by UL approvals and designed for
redundant protection architectures required by modern battery safety standards, three-terminal
fuses provide a robust and intelligent protection solution for advanced energy systems.

PPTC: Compact Protection for Maximum Reliability
The new PPTC series PFTA, PFTB, PFTC and PFTL provide reliable resettable overcurrent
protection for modern electronic applications. In the event of a fault, the polymer PTC device
automatically increases resistance to effectively protect systems against overloads and short
circuits — without replacing fuses.
The portfolio includes radial leaded and SMD versions with current ratings from 0.05 to 5 A and
voltage ratings up to 72 V. UL-compliant flame-retardant materials and compatibility with
automated assembly processes make these series ideal for industrial high-volume applications.
Applications:
Typical applications include energy storage systems, power supplies, industrial electronics,
consumer electronics, automotive systems, wearables, SSDs and Li-ion batteries. The compact
PFTL SMD series additionally enables space-saving designs with high integration density.
