Vishay Intertechnology's Thermal Fuses Are the Industry's First to Combine High Currents to 55 A
Vishay Intertechnology introduced the industry's first thermal fuses to offer high current capabilities up to 55 A and operation at temperatures up to + 160 °C for 1,000 hours without unexpected breakdown. AEC-Q200-tested, devices in the new Vishay Beyschlag HCTF series provide a safety interrupt of electrical power in high-current automotive applications.In t
The thermal fuses offer significantly higher current capabilities than other devices on the market, which are limited to 25 A at an ambient temperature of 23 °C or 12 A at an ambient temperature of 100 °C. The HCTF devices' robust solid-state design, in combination with low cold resistance of ≤ 0.1 mΩ, guarantees extended reliability at high current loads and ambient temperatures.
Devices in the HCTF series are RoHS-compliant and offer a rated voltage of 24 V. HCTF 235 fuses can be assembled with electric resistance welding while HCTF 235 CP devices can be inserted into clamp terminations. In either case, both versions can be assembled with crimping units, as well.
