U.L. Approved 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
