Vishay Intertechnology introduced the industry's first thermal fuse, without unintended open circuit for 1000 hours to work under the current 55 And at a temperature of +160 °C. standard, Qualified to AEC-Q200, the new series Beyschlag HCTF is designed for breaking high current circuits in automotive applications.
If the ambient temperature rises above threshold +235 °C (±15 K), the thermal cutoff automatically opens and disconnects the electrical circuit. Typical applications for HCTF power electronics, is permanently connected to the battery, such as fans and pumps of the coolant system control air intake, ABS, blocks pre-heating diesel engines and more.
Fuses are designed to operate at considerably higher power levels than any other devices present in the market today, operating currents which is limited to 25 A at 23 °C or 12 A at 100 °C. Durable solid-state design series HCTF in combination with low resistance in the cold state, is equal to 0.1 mω, guarantees high reliability operation at high currents and high temperatures.
Meet the requirements of the RoHS Directive device HCTF series is designed for operating voltage of 24 V. the HCTF 235 Fuses can be mounted by soldering, and the construction HCTF 235 CP involves the use of clamping contacts. If necessary, the clips can be installed on devices of both types.
Currently available as individual samples, and scale up batches of new devices. For large orders the delivery time is 14 weeks.
