Radial Leaded PTC

Resettable PTCs

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 immediate rise in resistance. In this condition, the

device provides circuit protection by significantly limiting the flow of

current. However, once the cause of the initial overcurrent condition

is eliminated, the 30R Series PTC cools down and resets to a low

resistance value permitting the normal current flow to resume.

• The 30R Series is a 30V Radial Leaded Device with a 40A Short

Circuit Rating.
