3425L250, SURFACE MOUNT PTC

RESETTABLE PTCs SURFACE MOUNT PTC 2029L/3425L Series ® ® TUV PRODUCT SERVICE The 2029L/3425L Series Resettable devices utilize a unique polymer-based, Positive Temperature Coefficient (PTC) material to protect electrical circuits against overcurrent conditions.

In normal operation, the 2029L/3425L 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 conduc
