KOA's Resistors: Linear Thin Film PTC



KOA’s SMD thin film thermosensitive resistors have a linear positive temperature coefficient and are perfect for temperature sensing, control and compensation.

The nickel based PTC thin film element on an alumina substrate ensures high stability over the entire temperature range.
