Ptc Resettable Fuses Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging configuration. Confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the selected variant aligns with specific thermal management requirements and spatial constraints on the target printed circuit board layout.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC system requires a 125 mA hold current threshold. Evaluate the 2.5 Ohm initial resistance against signal integrity or power loss constraints. Consider the 100 A maximum fault current capability relative to potential short-circuit scenarios in the application design.

Ptc Resettable Fuses Part Context

This part belongs to the 1206L series of POLYFUSE resettable fuses from Littelfuse. The series provides a range of current ratings within the standard 1206 package footprint. These components serve as reusable alternatives to traditional one-time fuse elements in low-voltage DC circuits.
