The low-ohmic device MICROSMD..F on polymer basis has a positive temperature coefficient (PTC). It is suited for protective functions of electronic applications within a voltage range up to 30 V. MICROSMD..F offers functions seen in a fuse, and upon heating (e.g. through over currents or short circuits) amplifies its resistivity from an initial low-ohmic resistor to a very high-ohmic resistor. MICROSMD..F is immune to manipulation and resets after debugging.
