THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 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 batter y power (B+ or terminal number 30).

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 -A B S - Diesel glow plug relays - Diesel pre-heaters - Electric coolant pumps Note (1) Current rating depends on external thermal management.

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Note (1) Products can be ordered using either the PART NUMBER or the PRODUCT DESCRIPTION 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)

  • The current rating factor depends on th e mounting and environmental conditions. The power dissipation on the thermal fuse gene rates 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).
