Vishay Beyschlag
High Current Thermal Fuse
FEATURES
• Functioning temperature: F = (235 ± 15) °C
• Holding temperature: H = 160 °C
• Current:  55 A
• Suitable for resistive welding systems
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Automotive
- Fan control units
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).
- ABS
- Diesel glow plug relays
- Diesel pre-heaters
- Electric coolant pumps

ASSEMBLY
The high current thermal fuse HCTF 235 is suitable for processing on e.g. automatic electric resistance welding or crimping
assembly systems. Any deformation and overheating of the component body to levels above the holding temperature has to be
avoided during the assembly.
The HCTF 235 CP complies with the JIG 101 list of legal restrictions on hazardous substances.
This includes full compliance with the following directives:
• 2000/53/EC End of Life Vehicle Directive (ELV) and Annex II (ELV II)
• 2011/65/EU Restriction of the use of Hazardous Substances Directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE)

Note
• The current rating factor depends on the mounting and environmental conditions. The power dissipation on the thermal fuse generates a
temperature rise against the local ambient, depending on the heat flow supported by additional conductive materials as electrical wires, lead
frames or other electrical connections (thermal resistance). Please contact the factory (please refer to e-mail contact below) for support and
further technical details.
