Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the exact inductance value and tolerance, as variations exist within the series. Confirm that the required current rating meets the application's peak load requirements. Ensure the unshielded nature of the component does not cause interference in dense layouts. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Fixed Inductors Selection Notes

Select this component when a compact 0805 footprint is required for moderate inductance values. Consider the self-resonant frequency limits to ensure suitability for the target operating range. Evaluate the DC resistance impact on power efficiency. Compare against shielded alternatives if electromagnetic interference suppression is critical for the surrounding circuitry.

Fixed Inductors Part Context

This part belongs to the 0805CS series of wirewound chip inductors from Delta Electronics. The series provides various inductance options in a standard 0805 package. These components are designed for general-purpose electronic applications requiring reliable passive filtering or energy storage in small form factors.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 0805 wirewound inductors with matching 390 nH inductance and similar current ratings. Verify pin compatibility and physical dimensions before swapping. Cross-reference specifications for Q-factor and self-resonant frequency to maintain circuit performance integrity.
