I =Hold current: maximum current at which the device will not trip at 25 stillair.

I =Trip current: minimum current at which the device will always trip at 25 stillair.

V

=Maximum voltage device can withstand without damage at rated current.

I

=Maximum fault current device can withstand without damage at rated voltage.

T

=Maximum time to trip(s) at assigned current.

Pd =Typical power dissipation: typical amount of power dissipated by the device when in state air environment.

R

=Minimum device resistance at 25 prior to tripping.

R

=Maximum device resistance measured in the nontripped state 1 hour post reflow.
