The low-ohmic device RXEF on polymer basis has a positiv temperature coefficient (PTC). It is suited for protective functions of electronical applications within a voltage range up to 72 V. RXEF offers functions seen in a fuse, and upon heating (e.g. through over currents or short curcuits) amplifies its resistivity from an initial low-ohmic resistor to a very high-ohmic resistor. RXEF is immune to manipulation and resets after debugging.
