105-103K

Overview

The Delevan 105-103K is a fixed power inductor designed for surface-mount technology (SMT) applications. It features an unshielded construction with a ferrite core and wirewound design, offering a nominal inductance of 10 µH with a tolerance of ±10%. The component supports a maximum DC current of 130 mA and exhibits a maximum DC resistance of 5.6 Ohms. It utilizes standard two-lead terminals for PCB mounting and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded wirewound construction utilizing ferrite core material
• Standard two-lead terminal configuration for through-hole or SMT integration
• Wide operational temperature stability from -55°C to +125°C

Applications

• General purpose RF filtering circuits
• Power supply choke applications
• Signal conditioning networks

Procurement Notes

Verify component authenticity and datasheet revisions prior to integration. Confirm that the specific lead configuration matches the target PCB footprint requirements. Ensure environmental compliance documentation aligns with project specifications, noting potential variations in RoHS status across different production batches.

Selection Notes

Select this component when a 10 µH inductance value is required with moderate current handling capabilities up to 130 mA. The high DC resistance of 5.6 Ohms distinguishes it from low-resistance power chokes, making it suitable for signal processing rather than high-current power delivery. Evaluate thermal management needs given the unshielded design.

Part Context

This part belongs to the broader category of fixed inductors manufactured by API Delevan. It shares functional similarities with other general-purpose inductors but is distinct due to its specific electrical parameters and physical form factor. It serves as a passive component in electronic assemblies requiring precise impedance characteristics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official manufacturer channels for cross-reference data or equivalent alternatives meeting identical electrical and mechanical specifications.
