One SMD fuse for use in both primary and secondary circuits streamlines processes

Schurter announces several new current ratings to its already popular UMT 250 series, for a total of twenty two unique ratings from 80mA to 10A. The series is designed to provide overcurrent and short-circuit protection in both primary and secondary circuits. The versatile one package solution streamlines design, procurement and automated assembly processes.

The UMT 250 maximizes circuit protection while its extremely compact size meets the demand for saving space and facilitating production. It can be mounted on both sides of the printed circuit board. Its low profile increases production rates when mounted with pick and place assembly machines. It is an ideal substitute for axial and radial leaded through-hole fuses where bending leads can cause assembly delays.

The Universal Modular Fuse (UMF) is time-lag (T) characteristic. It is rated at 250 VAC and 125 VDC, according to IEC and 277VAC and 250 VDC, according to UL. The series has a high breaking capacity of up to 200A at rated voltage. It is RoHS compliant and carries all the main approvals such as VDE, UL Listing, cURus, PSE Jet (Japan), CCC (China) and KTL (Korea). Applications include protection of power supplies, storage systems, wireless base stations and many other electronic systems.

Schurter announces the release of the first 1206 chip fuse series UST 1206 with rated current values up to 25 A and slow-blow characteristic. It boasts high melting I2t values, which provides good inrush withstand performance. It’s a cost-effective solution for applications in which high inrush current and on-off cycling are present.

The UST 1206 with characteristics according to UL 248-14 complements the USI 1206 with characteristics according to IEC 60127-4 . The current ratings of the UST 1206 range from 7 to 25 A with voltage ratings up to 63 VDC and 32 VAC. The device provides a breaking capacity of up to 400 A, and an operating temperature range of - 55°C to +90°C.

The fuse is designed to provide secondary over current protection in applications such as power inverters and back lit DC-AC inverters for monitors, where power consumption is high at a low voltage level, e.g. 5 or 12 VDC. The legend marking on each fuse allows a clear visual identification.

The fuse is approved according to UL 248-14 and holds a cURus approval. The device is RoHS compliant and is supplied on tape and reel either with 1k or 5k or 15k pieces.

Schurter’s new TF600 non-resettable fuse assists manufacturers of telecommunications equipment in meeting power cross and lightning surge requirements outlined in North American standards Telcordia GR-1089, TIA-968-A (formerly FCC Part 68), and UL 60950, as well as the international standards ITU-T K.20 and IEC 60950. The fuse has a rated breaking capacity of 60A at 600 Volt AC, over a current range of 0.5 - 2 Amps.

The TF 600 is RoHS compliant according to Directive 2002/95/EC. Its low profile and small footprint conform to industry norms for size, placement and process compatibility. Its time-lag tripping characteristic provides reliable secondary protection of secondary circuits in a variety of telecom systems and networking equipment designated for use around the world. Typical applications are customer premises equipment (CPE) like telephones and modems, high-speed transmission equipment like ADSL modems and splitters and analog line cards (SLIC’s).

The TF 600 is built to UL 248-14 and carries UL/CSA recognition.  It also holds a “Free of CCC” confirmation for China. It is supplied either on tape (2000 pieces) or loose in a bag (100 pieces).
