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
Operating : Maximum continuous voltage device can withstand without damage at rated current. This voltage is used for component Recognition under UL1434.
V
MAX
Interrupt : Maximum voltage that can be safely placed across a device in its tripped state.
I
MAX
Interrupt : Maximum fault current device can withstand without damage at rated operating voltage. This current is used for component Recognition under UL1434. Devices may trip
safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950 or GR1089 industry requirements.
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 measured one hour post-trip or post-reflow at 20°C.
* 250V
AC
interrupt products may help equipment pass ITU K.20, K.21 and K.45 recommendations and Telcordia GR-1089 Port Type 2 and 4 requirements.
† 600V
AC
interrupt products may help equipment pass UL60950, TIA-968-A and GR1089 Port Type 1, 3 and 5 requirements.
‡ Product is not currently available in a resistance matched or sorted option.
