General Description  
Polymer resettable fuse are made of polymeric PTC materials which is a matrix of  
polymer containing dispersed conductive particles. Generally, the device has a very  
low resistance. If an over-current happened, as a response to the damage current,  
the resistance will immediately increase to very high, reducing the current of the  
circuit to a safe value that the loading can carry. Once fault to the circuit is weed out  
and power is recuperated, the polymer will deflate itself , the device will reset and is  
ready for normal operation.
