Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical parameters, specifically the 33VDC voltage rating and 1.85A holding current. Confirm the package type corresponds to the 2920 (7351 Metric) dimensions. Ensure compliance with RoHS directives if applicable to the manufacturing region. Cross-reference manufacturer documentation to validate performance characteristics against application requirements before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when the operating circuit requires a 33VDC maximum voltage rating and a 1.85A continuous holding current. The 2920 package size must align with available PCB footprint constraints. Consider the thermal environment and trip time characteristics inherent to PPTC devices. Verify that the surface mount orientation suits the assembly process and mechanical stress requirements of the target application.

Ptc Resettable Fuses Part Context

This component is part of the broader YAGEO SMD series of resettable fuses. The series offers various voltage and current ratings across different package sizes to accommodate diverse electronic protection needs. The SMD2920 variant specifically targets applications requiring higher current handling within a standard surface mount form factor.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other manufacturers' PPTC fuses with identical 33VDC ratings and 1.85A holding currents in the 2920 package. Verify physical dimensions and terminal compatibility before substitution. Littelfuse SMD2920P185TSA shares similar specifications but requires verification of exact electrical curves.
