Dual Function

Fuse Resistors

F500 Series

Affords protection for semiconductor devices

Acts as a precision wirewound resistor and a fuse

Allows precise control of fusing point and time lag

Reduces the number of discrete components required

Eliminates unnecessary blowing due to transient conditions

Eliminates fire hazard and circuit board damage due to overheated components
