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
