Reset Chip Polymer PTC Thermistor Surface Mount SMD PPTC Resettable
Fuses 2012 0.1A 15V For USB Devices
Description
Aolittel's unique polymer formulation PTC (positive temperature
coefficient) devices offer superior circuit protection, with added
resettable feature, in traditional radial lead AND SMD Chip
packages. Similar to our extensive line of traditional fuse
products, our resettable fuses protect against harmful overcurrent
and short circuit conditions. However, our PTC devices can also be
used to protect against over temperature conditions not necessarily
caused by excessive current. Aolittel's PTC devices will reset
after power to the circuit is removed, the fault is cleared, and
power is reapplied to the circuit. This reset-ability protects
electronic equipment, which remains fully functional, and
eliminates the need for service personnel to physically replace a
fuse. Our PTC devices are used in a wide variety of industrial,
computer, battery, consumer electronics, telecom and automotive
applications where they help protect valuable electronic systems
and reduce warranty and services costs.
