The FKN-S 1WS is a small size flameproof fusible wirewound resistor designed to combine resistance functionality with a fusible protection function. It is suitable for circuit board protection applications where a compact resistor with defined fusing characteristics is required.
The resistor uses a noncombustible insulating coating with solvent-resistant and high-temperature-resistant characteristics. It provides a 300 ppm/°C resistance temperature coefficient and defined fusing test conditions for circuit designs that require specified electrical and protection characteristics.
As a 1WS fusible resistor, the FKN-S is suitable for electronic circuits requiring a compact flameproof wirewound resistor. Its small body size supports space-conscious circuit board designs while retaining the resistance and fusible functions of the component.
