General Introduction
The FWxxA Series of axial leaded wirewound resistors is designed to fuse under abnormal conditions such as sudden surges in
voltage or circuit malfunctions. The resistor will fuse upon application of 120 or 240 voltages.
The resistor will fuse safely if 120 or 240 V is applied. The time to fuse depends on the
resistance value.
** 7 W = 240 Vac only.
Materials
Resistor ............... Wire wound around a
ceramic core
Lead Wire ........................Tinned copper
Housing .......................... Insulated resin
