Ptc Resettable Fuses Procurement Notes

Verify the specific resistance tolerance and thermal characteristics against the official Vishay Ametherm datasheet for the CL20100120. Confirm that the 480 VRMS rating aligns with your system's peak voltage requirements. Ensure the radial lead spacing matches your PCB footprint design before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a high-voltage PTC solution is required for inrush limiting. The 10 Ohm resistance value suits applications needing moderate pre-charge times. Consider the 400 mA holding current limit to ensure it does not interfere with normal steady-state operation. Verify environmental compliance status if RoHS3 or REACH restrictions apply to your manufacturing process.
