Ptc Resettable Fuses Procurement Notes

Verify the specific suffix against official documentation, as variants like /12MR-A may indicate distinct packaging or material specifications compared to standard reel configurations. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compliance with RoHS directives and check for any product change notifications that might affect lead availability or physical attributes.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile surface-mount fuse is required for 12 V systems carrying up to 6 A continuous current. The 2920 package size offers a balance between current handling capacity and board space efficiency. Consider the 20 mOhms initial resistance for minimal voltage drop impact in sensitive low-voltage designs requiring fast response to overcurrent events.

Ptc Resettable Fuses Part Context

This part belongs to the POLY-FUSE 2920L series of resettable fuses from Littelfuse. The series provides solid-state overcurrent protection solutions suitable for diverse electronic applications. The 2920 metric designation refers to the specific surface-mount footprint dimensions, ensuring compatibility with automated pick-and-place manufacturing processes for high-volume production environments.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse substitution guides for verified alternatives. Cross-reference parameters such as hold current, trip current, and maximum voltage to ensure functional equivalence. Verify that any substitute maintains the same 2920 surface-mount package dimensions and thermal characteristics to preserve board layout integrity.
