The IRB80 metal-clad wire-wound economy resistor series from RARA offers a power rating of up to 80W with available resistance values between 0.1Ω and 910Ω (inductive design) or between 0.1Ω and 110Ω (non-inductive design). These high power resistors are available with tolerances of ±2.0%, ±3.0%, ±5.0% and ±10.0% other options available including inductive or non-inductive resistive windings. The IRB80 series from RARA comes in a durable metal case with flying leads and offers a temperature range from -55°C up to +200°C
