Description

The IRN50 flat and narrow type metal clad wire wound resistor series from RARA, offers a power rating of up to 50W on a heat sink and available resistance values between 1Ω and 420Ω. These high power and low inductance resistors are designed for industrial and other applications where space is at a premium, the flat design also allows for excellent heat dissipation. The IRN50 series from RARA offers an extruded aluminium housing which provides strong and rugged protection, with options of cement or silicone filling materials as well as tolerances as low as ±0.5%. This resistor series offers a temperature range from -55°C up to +200°C (cement filling material).
