R30R300, Radial Leaded PTC

Next Previous Resettable PTCs Radial Leaded PTC 30R Series ® ® The 30R Series Resettable devices utilize a unique polymer-based, Positive Temperature Coefficient (PTC) material to protect electrical circuits against overcurrent conditions.

In normal operation, the 30R Series PTC has many conductive paths and a very low resistance.

In an overcurrent condition, the temperature of the polymer material rises.

This dramatically reduces the conductive paths resulting in an im
