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 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.
