PTC Resettable Fuse

PTC Thermistor  in radial leaded resin coated through-hole rugged design, used instead of conventional fuses to protect load, such as transformers, instruments,  power supply, or electronic circuit, against overcurrent overload and short circuit,  for circuit protection inrush current limit function, by utilizing ceramic PTC thermistors thermal property that resistance increases sharply at Curie Temperature (also called Switch Temperature, Reference Temperature), reduces the current flow to the load to an admissible low level.
