: Hold current: maximum current device will pass without interruption in 20°C still air.
: Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air.
: Minimum resistance of device as supplied at 20°C unless otherwise specified.
: Maximum resistance of device as supplied at 20°C unless otherwise specified.
: Maximum continuous voltage device can withstand without damage at rated current.
: Under specified conditions this is the highest voltage that can be applied to the device at the maximum current.
: Maximum fault current device can withstand without damage at rated voltage.
: Power dissipated from device when in the tripped state in 20°C still air.
: Maximum resistance of device when measured one hour post reflow (surface-mount device) or one hour post trip
(radial-leaded device) at 20°C unless otherwise specified.
