Fixed Inductors Procurement Notes

Verify the specific suffix CA against the official Bourns datasheet to confirm ferrite core composition and temperature range. Ensure the ordering part number matches the required 4.5 µH value and 7 A current rating. Confirm packaging preferences such as tape and reel quantities directly with authorized distributors or the manufacturer to align with production needs.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor with high current handling is required for automotive or industrial power supplies. The 6.6 mm square footprint suits space-constrained designs. Compare saturation current (9.5 A) against peak load requirements. Verify thermal management capabilities given the 155°C operating limit and low DCR for efficiency optimization.

Fixed Inductors Part Context

This part belongs to the Bourns SRP6030CA series of shielded power inductors. The series offers various inductance values within the same 6.6x6.6x2.8 mm package. It targets applications requiring robust magnetic shielding and high current density. The CA suffix denotes specific core material and electrical characteristics distinct from other series variants like WA or VA.

Fixed Inductors Replacement Considerations

Direct substitutes include other SRP6030CA-4R5M units from different authorized sources. Cross-referencing requires matching 4.5 µH, 7 A Irms, 9.5 A Isat, and 25.3 mΩ DCR. Alternative brands must meet AEC-Q200 if automotive use is intended. Verify pin compatibility and thermal performance before substitution.
