Fixed Inductors Procurement Notes

Verify the specific part number SRP1245CC-100M against official Bourns documentation to confirm the carbonyl powder core composition and 11 A rated current specifications. Ensure compatibility with required operating temperature ranges and surface mount footprint dimensions before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when high saturation current and low DC resistance are critical for power efficiency. The shielded design minimizes magnetic field interference in dense layouts. Verify that the 10 µH inductance value aligns with target circuit requirements and switching frequencies.

Fixed Inductors Part Context

This component belongs to the SRP1245CC series of shielded power inductors manufactured by Bourns. The series utilizes carbonyl powder cores to achieve high current handling capabilities within a compact surface mount package. It is distinct from ferrite-core variants like the standard SRP1245A.

Fixed Inductors Replacement Considerations

Direct substitutes include other Bourns SRP1245CC series parts with matching inductance and current ratings. Cross-reference electrical parameters such as DCR and saturation current when considering alternative manufacturers' components.
