Surface Mount - PolySwitch® Resettable PPTC Devices

A collection of Surface Mount PolySwitch Resettable PPTC Devices
Surface mount PolySwitch® resettable PPTC fuses solder onto printed circuit boards. The surface mount devices employ polymer positive temperature coefficient technology to protect electronic components and integrated circuits from inrushes of current. Since the SMD fuses only blow when massively overloaded, they rarely require replacement. The resettable fuses’ miniature and subminiature sizes make them ideal choices when space is limited, such as in mobile phones, portable medical devices, and USB peripherals. Littelfuse also offers AEC-Q200-qualified surface mount PPTC fuses for automotive applications.
