unique polymer-based, Positive Temperature Coefficient
(PTC) material to protect electrical circuits against over-
current conditions.
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 signif-
icantly limiting the flow of current. However, once the
cause of the initial overcurrent condition is eliminated,
the 2029L/3425L Series PTC cools down and resets to a
low resistance value permitting the normal current flow
to resume.
