105-102K

Overview

The Delevan 105-102K is a fixed, unshielded radial through-hole inductor designed for general-purpose DC applications. It features a nominal inductance of 1 µH with a tolerance of ±10%. The component supports a maximum rated current of 360 mA and has a maximum DC resistance of 730 mΩ. It utilizes a nonstandard two-lead package configuration suitable for vertical mounting on printed circuit boards.

Feature Summary

• Unshielded wirewound construction for standard electromagnetic interference environments
• Radial through-hole termination style enabling reliable PCB mounting
• Ferrite core material providing stable inductance characteristics

Applications

• General-purpose DC power filtering circuits
• Signal conditioning stages requiring low-inductance chokes
• Basic electronic assembly prototyping

Procurement Notes

Verify component authenticity upon receipt as the manufacturer API Delevan may have undergone corporate restructuring or acquisition. Confirm that the received part matches the specified 1 µH value and 360 mA rating against original datasheets. Ensure the radial lead configuration aligns with the target PCB footprint design requirements before final integration.

Selection Notes

Select this component when a low-cost, unshielded through-hole inductor is required for non-critical RF applications. The 1 µH value suits basic filtering needs where high Q-factor is not essential. Consider alternative SMD packages if space constraints prevent the use of radial leads. Validate thermal performance at the full 360 mA operating current to ensure reliability.

Part Context

This part belongs to the broader family of Delevan fixed inductors, which includes various shielded and unshielded configurations. The 105 series specifically denotes radial through-hole components. These inductors are distinct from surface-mount RF chokes like the S1812R series, offering different mechanical mounting solutions for diverse board layouts.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any potential cross-reference parts by matching inductance, current rating, and physical dimensions.
