HCTF Series
Vishay Beyschlag
High Current Thermal Fuse
The HCTF series is especially designed for high current
applications with an operation temperature up to 160 °C.
In case of excess heat in the range of the functioning
temperature of (235 ± 15) °C the thermo fuse opens
automatically and disconnects the circuit. Typical
applications are automotive power electronics that are
connected to steady battery power (B+ or terminal
number 30).
