IRN series

Supporting Manufacturer Information


Experience engineering precision with the IRN Series, a lineup of metal-clad resistors designed for industrial applications. The IRN models, featuring a narrow and flat design, deliver high-power performance ranging from 50W to 150W with low inductance. Housed in aluminum chassis, these wirewound resistors ensure rugged protection in demanding environments. The resistance spans from 1Ω to 1.75kΩ, providing flexibility for various projects. Tolerances of ±0.5%, ±1%, ±2%, ±5%, and ±10% guarantee accuracy, while a maximum Temperature Coefficient of Resistance (TCR) of 260ppm/℃ ensures stability. Suitable for diverse applications such as motor drives, braking, and power sources in industrial settings, the IRN Series excels with its flat design, allowing excellent heat dissipation. Explore the precision of the IRN Series for reliable performance in challenging conditions.
