= Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec.
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.
