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

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.
Disclaimer Notice - Information furnished is believed to be accurate and reliable. However, users should independently evaluate the suitability of and test each
product selected for their own applications. Littelfuse products are not designed for, and may not be used in, all applications.
