I = Hold current: maximum current device will pass without tripping in 20°C still air. R = Minimum resistance of device in initial (un-soldered) state. hold min I = Trip current: minimum current at which the device will trip in 20°C still air. R = Typical resistance of device in initial (un-soldered) state. trip typ V = Maximum voltage the device can withstand without damage at rated current (I max) R = Maximum resistance of device at 20°C measured one hour after tripping. int 1max V = The device regular operation voltage I op = Maximum fault current device can withstand without damage at rated voltage (V ) * Effective February 11, 2010 onward, all 600R PTC products will be manufactured Halogen Free (HF). Existing Pm a x= Power dissipated from device when in the tripped state at 20°C still air. max Non-Halogen Free 600R PTC products may continue to be sold, until supplies are depleted. This change will d 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. © 2020 Littelfuse, Inc.
