Overview
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 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.
