Although NR relays are rated at 10 G/55 cps. vibration resistance, they will with-
stand up to 60 G/2,000 cps., provided they receive additional support such as
anchoring to the PC board with epoxy resin.
Refer to 5. Conditions for operation, transport and storage mentioned in
AMBIENT ENVIRONMENT (Page 61)
Total temperature (ambient temperature plus temperature rise in coil) should not
exceed 90°C 194°F for single side stable, and 105°C 221°F for latching relays.
See Reference Data for determination of coil voltage versus temperature.
