Supporting Manufacturer Information


Introducing the IRB metal-clad, wire-wound resistors series, a budget-friendly solution for applications requiring up to 120W. Encased in durable metal, these resistors boast flying leads, ensuring versatility. The IRB series offers three models, IRB60, IRB80 and IRB120, covering power ratings from 60W to 120W. With resistance values ranging from 0.1Ω to 1.3KΩ(inductive) or 300Ω (non-inductive), these resistors exhibit precision with tolerances of ±2% up to ±10% and a TCR of ±260ppm/°C max. Operating in a wide temperature range from -55°C to +200°C, they demonstrate reliability in various conditions. The series also features excellent insulation resistance, dielectric withstand voltage, and resistance to moisture, thermal shock, and vibration. Choose the IRB series for cost-effective, high-performance metal-clad economy resistors. Learn more at www.raraohm.com.
