The device regular operation voltage Maximum fault current device can withstand without damage at rated voltage (Vmax) **R min =** Minimum resistance of device in initial (un-soldered) state. **R typ =** Typical resistance of device in initial (un-soldered) state. **R 1max =** Maximum resistance of device at 20°C measured one hour after tripping. ***** Effective February 11, 2010 onward, all 600R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 600R PTC products may continue to be sold, until supplies are depleted. This change will 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. © 2021 Littelfuse, Inc.
