Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet for the CHNR5040-330M-00000 to confirm electrical tolerances and thermal characteristics. Ensure that the sourcing channel provides original components with traceable documentation. Cross-reference the part number against official Chipsen catalogs to validate authenticity before procurement.

Fixed Inductors Selection Notes

Select this component for applications requiring a 33 µH inductance with a 1.2 A current rating. Consider its shielded design for environments sensitive to magnetic noise. Verify that the 5040 package dimensions fit the target PCB layout constraints and that the operating temperature range meets the system requirements.

Fixed Inductors Part Context

This inductor belongs to the CHNR series, which includes similar models like the CHNR4030 variants. These components are manufactured by Dongguan Chipsen Electronics Technology Co., Ltd. The series is designed for surface-mount technology applications, providing reliable performance in compact electronic designs.

Fixed Inductors Replacement Considerations

The Bourns SRN5040-330M is a comparable shielded wirewound inductor with identical 33 µH inductance and a 5040 package. However, it specifies a higher current rating of 1.2 A and a lower DCR of 216 mΩ. Verify compatibility regarding saturation current and physical footprint before substitution.
