Notes:
I
H
: Hold current: maximum current device will pass without interruption in 20°C still air.
I
T
: Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air.
V
MAX
: Maximum continuous voltage device can withstand without damage at rated current.
I
MAX
: Maximum fault current device can withstand without damage at rated voltage.
P
D
: Power dissipated from device when in the tripped state in 20°C still air.
R
MIN
: Minimum resistance of device as supplied at 20°C unless otherwise specified.
R
MAX
: Maximum resistance of device as supplied at 20°C unless otherwise specified.
R
1MAX
: 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.
* Electrical characteristics determined at 25°C.
