HCTF Series www.vishay.com 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 TECHNICAL SPECIFICATIONS DESCRIPTION HCTF 235 Functioning temperature F (235 ± 15) °C Holding temperature H (1000 h) 160 °C 24 V Voltage UDC Current IDC 55 A (1) 0.1 m Cold resistance Rcold Residual resistance Rs after breaking > 1 M Note (1) Current rating depends on external thermal management.

IEC 60286-3 type III 32 mm 12 mm 360 mm/14.2" 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) RELATED PRODUCTS A version for automatic insert systems is available, too.
