Cement Resistors with Thermal Cut-offs - FKU/FRU Series
Ultimate Protection Thermal Cutoffs
for High Power Applications
Preview
Fast-acting protection device for high-power applications combines thermal fuse element and resistor on a single
substrate.
Token offers FKU (Wirewound Resistor + Thermal Cut-offs) and FRU (Metal Oxide Film Resistor + Thermal
Cut-offs) two Series, both are a new concept in thermal fuse technology and are designed to protect against overheating in electrical products.
The two active components, a thermal cutoff is a fusible alloy and a resistor is a voltage divider, both are
surrounded by a ceramic cement with special resin. Under normal operating temperatures the fusible alloy joins
the two lead wires within the body of the cutoff and the power resistor acts as a normal function resistor. When
the preset temperature of the cutoff is reached, the fusible alloy melts and with the aid of the special resin,
complete cutoff is ensured.
By combining a thermal fuse element and resistor on a single substrate, Token has created a fast-acting ultimate
protection device for high power applications up to 10A/250V.
Resistance range of FKU Wirewound Type Thermal Cut-offs is 1Ω~100Ω and FRU Metal Oxide Film Type
Thermal Cut-offs is 110Ω~10KΩ. Both standard precision tolerance is J(±5%).
Our custom solutions are designed to address your need for technical and economic success in a timely manner.
