I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
I trip = Trip current: minimum current at which the device will trip in 20°C still air.
R typ = Typical resistance of device in initial (un-soldered) state.
V max = Maximum voltage device can withstand without damage at rated current (I max)
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow
soldering of 260°C for 20 sec.
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd = Power dissipated from device when in the tripped state at 20°C still air.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
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.
