The maximum operate power that can be applied is 0.75 watt
per coil at +25oC, de-rated linearly to 0.5 watt at +125oC. LF
relays are suitable for short-pulse operation and the pulse
power may be increased in inverse ratio to the duty cycle
when used in this mode, with a limit ratio of 16:1. The
minimum pulse lengths are 3 ms. Pulse power is the
continuous power divided by the duty cycle, where the duty
cycle equals the pulse lengths divided by the time for one
cycle.
