FKN Wirewound fuse resistor is fusible and designed to meet where applications require high power dissipation. This device meets the requirements to withstand an inrush surge, and also a lightning strike, which is the ability of the resistor to fuse safely should a short circuit occur (for example if the bridge rectifier were to fail short circuit).
Utilising a specially designed coating system formulated to aid fusing under fault conditions – Fuse Aid. Designers of small power supplies and battery chargers for consumer products can benefit from a fusible resistor with superior lightning strike and pulse abilities in a cost effective package.
