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:
