108-563K

Overview

The Delevan 108-563K is a fixed surface-mount inductor designed for general-purpose applications. It features an unshielded construction with a nominal inductance of 56 µH and a tolerance of ±10%. The component supports a maximum DC current of 33 mA and exhibits a maximum DC resistance of 23 Ohms. It utilizes a nonstandard two-lead SMD package configuration.

Feature Summary

• Surface-mount design for automated PCB assembly
• Unshielded magnetic structure to minimize size
• Ferrite core material for stable inductance

Applications

• General purpose signal filtering
• Power supply input/output stages
• RF circuit impedance matching

Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant or lead-containing in available documentation. Confirm availability through authorized distributors, noting that stock levels may vary. Ensure the specific suffix matches the required lead configuration and packaging format for integration.

Selection Notes

Select this component when a compact, unshielded inductor is required for low-current applications. The high DC resistance limits suitability for high-power circuits. Verify thermal performance at the specified 33 mA limit and ensure the nonstandard footprint fits the target PCB layout constraints.

Part Context

This part belongs to the Micro iDent Chip Inductors series by API Delevan. It represents a legacy SMD inductor option within the manufacturer's passive component portfolio, distinct from their shielded power inductor lines like the SP1210 series.

Replacement Considerations

Direct substitutes include other 56 µH SMD inductors with similar current ratings. Check datasheets for equivalent DCR and saturation characteristics. No official cross-reference part numbers are confirmed in public documentation.
