Fixed Inductors Procurement Notes

Verify the specific suffix against official Bourns documentation to ensure correct electrical ratings and packaging configuration. Confirm that the requested quantity matches the manufacturer's standard reel specifications. Cross-reference the date code and lot number with the latest production notices to ensure compliance with current manufacturing standards.

Fixed Inductors Selection Notes

Select this component when high saturation current and low AC losses are required in compact designs. The wide side terminal design facilitates robust surface mounting. Ensure the operating environment stays within the specified -55°C to +165°C range. Verify that the 11.5 A DC current rating meets the continuous load requirements of the target circuit application.

Fixed Inductors Part Context

This part belongs to the Bourns SRP series of shielded power inductors. The series is designed for high-current applications requiring low profile and high reliability. The SRP7050WA variant specifically utilizes a metal alloy powder core to achieve superior saturation characteristics compared to traditional ferrite cores.

Fixed Inductors Replacement Considerations

Direct substitutes include other SRP7050WA variants with different inductance values or current ratings from Bourns. Cross-vendor replacements require matching the 7.3mm x 7.3mm footprint, 5.2mm height, and equivalent 3.3 µH inductance with similar saturation and DCR specifications.
