Notes:
1 Consult factory for life expectancy at other switching loads.
2 Surface mount component processing temperature: 500°F / 260°C max for 1 min-
ute dwell time. Temperature measured on leads where lead exits molded package.
3 Higher dielectric strength available, consult factory.
Environmental Ratings:
Storage Temp: -35°C to +100°C; Operating Temp: -20°C to +85°C
All electrical parameters measured at 25°C unless otherwise specied.
Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s
