Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 1.5 A holding current and 33 VDC rating. Confirm the package type is 2920 and ensure compliance with RoHS standards if applicable. Check datasheet specifications for thermal derating requirements at elevated operating temperatures above 25°C to ensure proper circuit performance.

Ptc Resettable Fuses Selection Notes

Select this component when a surface-mount solution is required for low-voltage DC circuits. The 1.5 A holding current suits applications with steady-state currents below this threshold. Consider the 2920 package size for available PCB space. Ensure the maximum trip current of 3 A aligns with the circuit's fault tolerance limits before integration into the design.

Ptc Resettable Fuses Part Context

This component belongs to the YAGEO SMD series of resettable fuses, which are manufactured as polymeric devices. The SMD2920B150TF specifically utilizes the 2920 case style, providing a standardized footprint for automated assembly processes. It is categorized under PPTC resettable fuses within the broader portfolio of passive electronic components offered by the manufacturer.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other 2920 package PPTC fuses with identical or compatible electrical ratings. Verify that alternative parts maintain the same 1.5 A holding current and 33 VDC maximum voltage. Ensure the replacement device supports the same operating temperature range and meets the required 3 A trip current specification for equivalent circuit protection performance.
