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.
