I trip = Trip current: minimum current at which the device will trip in 20°C still air. 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. R min = Minimum resistance of device in initial (un-soldered) state. - R 1max = 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. © 2023 Littelfuse, Inc.

## **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.
