Shaped 2D PTC Heaters
PTC heaters self regulating heaters in simple and complex 2D & 3D shapes that provide a highly
reliable product for demanding applications.
PTC Current Limiters used to limit the current in a circuit in the event of a fault condition. Used in
place of conventional fuses but typically do not require replacement in the event of a fault.
