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 0.1ฮฉ to 1.3Kฮฉ(inductive) or 300ฮฉ (non-inductive), these resistors exhibit precision with tolerances of ยฑ2% up to ยฑ10% and a TCR of ยฑ260ppm/ยฐC max. Operating in a wide temperature range from -55ยฐC to +200ยฐC, 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.
