TOKEN FKU/FRU Thermal Cut-offs Resistors Thermal Cut-offs Resistors 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. Contact us with your specific needs.
