The low-ohmic device RUEF on polymer basis has a positive temperature coefficient. It is suited for protective functions of electronical applications within a voltage range up to 30 V. RUEF 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. RUEF is immune to manipulation and resets after debugging.
