10HC-27

Overview

The Delevan 10HC-27 is a fixed wirewound inductor featuring an unshielded drum core design. It provides an inductance of 27 µH with a maximum DC resistance of 18 mΩ and supports a current rating of 10 A. The component utilizes a radial, horizontal cylinder open package for through-hole mounting. Electrical testing is specified at a frequency of 1 kHz.

Feature Summary

• Unshielded drum core construction
• High current handling capability
• Through-hole radial mounting configuration

Applications

• RF inductor circuits
• General purpose power filtering
• High current choke applications

Procurement Notes

Verify the specific manufacturer designation, as API Delevan products are often listed under API Delevan Inc. or Delevan. Confirm that the 18 mΩ DCR specification aligns with your circuit requirements. Ensure the through-hole radial package dimensions fit the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when high current capacity is required alongside moderate inductance values. The unshielded design necessitates careful placement to avoid magnetic interference with nearby sensitive components. Verify thermal management capabilities for continuous operation at the rated current level.

Part Context

This part belongs to the 10HC series of high-current filter chokes manufactured by API Delevan. The series offers various inductance options within a standardized radial package form factor. These components are designed for robust performance in demanding power electronics environments requiring reliable inductive filtering.

Replacement Considerations

Cross-reference with other 27 µH, 10 A radial through-hole inductors from manufacturers such as Bourns or Coilcraft. Ensure equivalent DCR and saturation current ratings are met. Verify mechanical footprint compatibility for direct replacement without PCB modification.
