## **Notes:** IH : Hold current: maximum current device will pass without interruption in 20°C still air. IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air. VMAX Operating : Maximum continuous voltage device can withstand without damage at rated current. This voltage is used for component Recognition under UL1434. VMAX Interrupt : Maximum voltage that can be safely placed across a device in its tripped state. IMAX Interrupt : Maximum fault current device can withstand without damage at rated operating voltage. This current is used for component Recognition under UL1434. Devices may trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950 or GR1089 industry requirements. PD : Power dissipated from device when in the tripped state in 20°C still air. RMIN : Minimum resistance of device as supplied at 20°C unless otherwise specified. RMAX : Maximum resistance of device as supplied at 20°C unless otherwise specified. R1MAX : Maximum resistance measured one hour post-trip or post-reflow at 20°C. - 250VAC interrupt products may help equipment pass ITU K.20, K.21 and K.45 recommendations and Telcordia GR-1089 Port Type 2 and 4 requirements. † 600VAC interrupt products may help equipment pass UL60950, TIA-968-A and GR1089 Port Type 1, 3 and 5 requirements. - Product is not currently available in a resistance matched or sorted option. © 2025 Littelfuse, Inc.

**Figure 2** ## **Warning** - Users should independently evaluate the suitability of and test each product selected for their own application. - Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. - These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. - Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices. - Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components. - PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion. - Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the 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. Read complete Disclaimer Notice at www.littelfuse.com/disclaimer-electronics. © 2025 Littelfuse, Inc.
