The FKN-S series is a small-size flameproof fusible wire wound resistor designed for circuit protection applications where resistance and fusible protection functions are required in the same component.
The resistor uses a wire wound construction with a noncombustible insulating coating. The product documentation specifically identifies it as suitable for circuit board protection. The 3WS version provides a resistance range of 0.1–800Ω and a 500V dielectric withstand voltage rating.
Its specified fusing characteristic is a fusing time of within 60 seconds under the stated test condition. The product documentation also specifies a temperature coefficient of 300 ppm/°C and test conditions covering −55°C to +200°C, providing defined electrical and environmental parameters for component selection.

The 3WS specification, resistance range, dielectric withstand voltage, temperature characteristics and fusing characteristics are based on the product documentation.
The FKN-S 3WS fusible resistor is designed for applications requiring circuit board protection with a defined fusible characteristic. Its flameproof wire wound construction and noncombustible insulating coating are specified features of the product.
The 3WS version combines a 0.1–800Ω resistance range, 300 ppm/°C temperature coefficient, and fusing time within 60 seconds under the specified test condition. These parameters can be used by engineers when evaluating a fusible wire wound resistor for circuit protection applications.
The available product documentation specifically identifies circuit board protection as the application. It does not specify particular automotive, EV, inverter, charger, or other end-product applications, so these applications are not claimed here without additional technical evidence.
