Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to ensure correct packaging and lead configuration. Confirm that the 16R1200GMR designation matches the required 12 A hold current and 16 VDC rating for your design. Cross-reference RoHS compliance status directly with the manufacturer's latest release notes before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit designs require a resettable fuse with a 12 A continuous operating current. Ensure the application voltage does not exceed the 16 VDC maximum rating. Verify that the expected trip current of 20.4 A aligns with the system's surge tolerance. Consider the radial lead spacing and PCB footprint dimensions during layout planning.

Ptc Resettable Fuses Part Context

This part belongs to the 16R series of PolySwitch resettable fuses, which are widely used for general-purpose circuit protection. The series provides various hold current options within a compact radial-leaded form factor. These devices serve as alternatives to traditional one-time fuses in applications requiring repeated fault recovery without manual replacement.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic cross-references may not match the precise trip characteristics or package dimensions.
