Brand Story.png


Fusible Wirewound Resistor (RXF) is a power resistor, which is made by winding a resistive element on a ceramic core, and the core is coated by insulation coating. As a Protective Component, RXF works as a fixed resistor in normal operation, and is designed to open the circuit under the overload condition.


SETsafe | SETfuse RXF is attractive owing to its Miniaturized Size and Superior Properties and it has already been approved by UL, cUL, CQC, VDE. It also complies with RoHS, REACH.
