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.
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.
