Littelfuse PolySwitch and POLY-FUSE Resettable PPTCs

Littelfuse PolySwitch and POLY-FUSE Resettable are Polymeric Positive Temperature Coefficient (PPTC) devices that provide a resettable overcurrent protection option, reducing warranty, service, and maintenance. PolySwitch and POLY-FUSE Resettable PPTCs are available in surface mount, radial leaded, battery strapped, low resistance, telecom, bladed, line voltage rated, and TD and chip resettable configurations. These PolySwitch and POLY-FUSE PPTCs are appropriate for scenarios requiring frequent overcurrent protection or continuous uptime.

Littelfuse PolySwitch and POLY-FUSE resettable PPTCs offer a maximum voltage range of 6V to 600V and a maximum fault current range of 1A to 100A. PolySwitch and POLY-FUSE PPTCs are typically used in consumer electronics, power lines, telecom, I/O port, process control, and medical equipment protection applications.
