- Modems/ Ethernet/LAN 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.
