Metal clad resistance for high power use. It has a shape that can be fixed directly to the chassis and has superior heat dissipation compared to other resistors. The terminals connected to the resistance are shaped like flat connecting terminals (tab terminals). Has a hole of Φ2. Resistance Value: 20 Ω Tolerance ± 5% Rated Power: 25 W Usable Temperature Range: -55 °C to +155 °C Chassis Mounting Screw Hole Diameter: 0.14 °F (3.5 °C)
