PD54R-103K

Fixed Inductors Overview

The Delevan PD54R-103K is a fixed power inductor designed for surface-mount applications. It features an unshielded drum core construction with wirewound technology. The component provides an inductance of 10 µH with a tolerance of ±10%. It supports a maximum DC current of 1.44 A and has a maximum DC resistance of 100 mΩ. The unit utilizes a nonstandard package configuration suitable for PCB mounting.

Fixed Inductors Feature Summary

• Utilizes unshielded drum core architecture for specific magnetic field management
• Employs wirewound construction to ensure stable inductance characteristics
• Designed for direct surface-mount integration onto printed circuit boards

Fixed Inductors Applications

• Power supply filtering circuits
• DC-DC converter input or output stages
• General power electronics signal conditioning

Fixed Inductors Procurement Notes

Verify the specific nonstandard footprint dimensions against your PCB layout, as standard SMD packages may not apply. Confirm that the 1.44 A current rating aligns with your peak load requirements. Ensure the unshielded design does not interfere with nearby sensitive components due to potential electromagnetic emissions during operation.

Fixed Inductors Selection Notes

Select this component when a 10 µH value is required with moderate current handling capabilities. The unshielded design offers cost advantages but requires careful placement to manage interference. Consider the nonstandard package size during mechanical assembly planning. This part suits applications where high-frequency shielding is less critical than thermal performance and current capacity.

Fixed Inductors Part Context

This component belongs to Delevan's range of fixed power inductors. It serves as a passive energy storage element within electronic circuits. The PD54R series distinguishes itself through robust wirewound construction. It targets designers needing reliable inductance without the bulk of shielded alternatives.

Fixed Inductors Replacement Considerations

The PD54R-103K is functionally equivalent to the Mouser-listed part number PD54R-103K from TTI Europe. Both sources identify it as a 10uH 10% Choke SMT with similar electrical parameters.
