fault events typically found in telecom applications. This
series is designed to be used in applications that need to
meet the requirements of GR–1089-CORE and UL60950/
EN60950/IEC60950. These resettable devices also help
to meet the requirements of ITU K.20, K.21 and K.44.

I
hold
= Hold current: maximum current device will pass without tripping in 23°C still air.
I
trip
= Trip current: minimum current at which the device will trip in 23°C still air.
V
int
= Maximum voltage the device can withstand without damage at rated current (I max)
V
op
= The device regular operation voltage
I
max
= Maximum fault current device can withstand without damage at rated voltage (V
max
)
P
d
= Power dissipated from device when in the tripped state at 23°C still air.
R
min
= Minimum resistance of device in initial (un-soldered) state.
R
typ
= Typical resistance of device in initial (un-soldered) state.
R
1max
= Maximum resistance of device at 20°C measured one hour after tripping.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
*
* Effective February 11, 2010 onward, all 600R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 600R PTC products may continue to be sold, until
supplies are depleted. This change will have no effect on 600R product specifications or performance.
