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 max = Maximum 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.  
WARNING  
• Users shall independently assess the suitability of these devices for each of their  
applications  
• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can  
adversely affect the performance of these PPTC devices  
• 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 undergo thermal expansion under fault conditions, and thus shall be  
provided with adequate space and be protected against mechanical stresses  
•
These devices are intended to protect against the effects of temporary over-current or over-  
• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the  
PPTC device.  
temperature conditions and are not intended to perform as protective devices where such  
conditions are expected to be repetitive or prolonged in duration
