TDK Product Features

TDK offers PTC limit temperature sensors and motor protection sensors. PTC limit temperature sensors are temperature-dependent ceramic semiconductive resistors whose resistance rises significantly at a specified temperature, thus protecting applications from overheating. The portfolio covers SMD components, leaded devices and simple systems. Motor protection sensors are designed to be directly mounted within the windings of electric motors.
