POWER SOLUTION - NIKKOHM 50W to 500W HIGH POWER WIRE WOUND RESISTORS FLAT SHAPED ALUMINUM HOUSED IRN50-IRN150 IRF150-IRF500 Features and Applications Non-inductive, flat shaped aluminum housed wire wound fixed resistors with 50W to 500W.. Minimum resistance of 1ohm, +/-0.5% tolerance available. 10mm thickness allows excellent heat extrusion from resistor. Narrower body (IRN) will be suitable for high density installation. Light weight silicone filled insulation and higher temperature operating cement filled insulation are prepared. Strong over load characteristics are fit for applications of industrial power electronics, switching power supplies, braking resistors for motor control electronics, rush current protection in automotive electronics, industrial power supplies.
