High power film resistor

Nikkohm high-power film resistors are innovative resistors available in various styles such as surface mount, through-hole, and chassis mount, allowing for efficient heat dissipation from the metal flange on the back of the resistor. The resistive element is formed on an alumina substrate with high thermal conductivity using thin film or thin film processes, demonstrating low reactance and pure resistance over a wide frequency range from DC to several hundred MHz, making it suitable for use as resistors in power electronics devices that operate in pulse mode. The resistive element is completely insulated from the metal flange and has an insulation voltage rating of 2kV to 5kV, allowing it to be used in the main circuits of power electronics. The rated power ranges from 20W to 800W, with resistance values from 0.1Ω to 1MΩ, and the standard resistance tolerance is 1% or 5%.
