Disk and Washer Resistor
High-energy resistors in solid disk and washer styles from 1.60 to 5.90 inches (40.6 to 150 mm) in diameter.
| Maximum temperature | 230°C (446°F) |
|---|---|
| Maximum peak Voltage | 5000 Volts |
| Contacts | Brass metallization on faces |
| Recommended contact pressure |
25 psi minimum; 50-100 psi preferred |
| Power rating | Dependent upon mounting and exposed surface area. In free air, parts will safely dissipate 2.5 watts per square inch of surface area at 40°C (104°F) ambient. |
| Resistance temperature coefficient |
0.0%/°C to -0.1%/°C |
