600R Series
Description
The 600R Series is designed to protect against power 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 20°C still air.
I trip =Trip current: minimum current at which the device will trip in 20°C still air.
Vint = Maximum voltage the device can withstand without damage at rated current (I max)
Vop= The device regular operation voltage
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.
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax
)
P d = Power dissipated from device when in the tripped state at 20°C still air.
* 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.
WARNING
• Users shall independently assess the suitability of these devices for each of their applications
• Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire
•
These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such
conditions are expected to be repetitive or prolonged in duration
• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices
•
These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses
• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.
