Ptc Resettable Fuses Procurement Notes

Verify that the ordering suffix matches the required reel quantity and tape specification. Confirm RoHS compliance status through official manufacturer documentation. Ensure the lead-free designation aligns with your assembly process requirements. Cross-reference the datasheet revision date to guarantee parameter accuracy before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection requires a low-profile surface mount solution with specific current thresholds. The 1.1A hold current suits applications needing moderate overcurrent tolerance. The 33V rating limits usage to low-voltage DC circuits. Evaluate thermal dissipation needs against the 85°C operating limit during selection.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD2920 series of surface mountable PTC resettable fuses. The series offers various current ratings within the same 2920 package footprint. This specific model provides a balance between compact size and adequate current handling for general consumer electronics protection.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 2920 package, 1.1A hold current, and 33V rating. Verify equivalent trip characteristics and thermal performance. Check for identical mounting orientation and solderability requirements to ensure seamless integration.
