10HCR-68

Overview

The Delevan 10HCR-68 is a fixed power inductor with an inductance of 68 µH and a tolerance of ±10%. It features a drum core, wirewound construction with an unshielded design. The component has a maximum DC resistance (DCR) of 27 mΩ and a rated current of 10 A, with a saturation current of 9 A. It utilizes a radial, horizontal cylinder package for through-hole mounting. The operating temperature range spans from -55°C to +105°C, and it complies with RoHS3 standards.

Feature Summary

• High-current capability with a 10 A rated current and low 27 mΩ DC resistance for efficient power handling.
• Robust drum core wirewound construction designed for demanding power applications.
• Unshielded axial/radial form factor suitable for open-board layouts.

Applications

• Power supply filtering
• Choke applications in high-current circuits
• General power electronics

Procurement Notes

Verify the specific packaging configuration, as the 10HCR-68 is typically supplied in bulk quantities rather than tape and reel. Confirm that the radial lead spacing of 28.58 mm aligns with the target PCB footprint. Ensure the unshielded nature of the component does not interfere with nearby sensitive circuitry during assembly.

Selection Notes

Select this component when a high-current inductor with low DC resistance is required for power stages. The 68 µH value and 10 A rating make it suitable for energy storage or filtering in power converters. Consider the physical dimensions of 34.93 mm length and 23.80 mm diameter to ensure adequate board space allocation.

Part Context

The 10HCR-68 belongs to the HCR series of fixed inductors manufactured by Delevan. This series is characterized by its ability to handle significant current loads while maintaining stable inductance values. The part is distinct from lower-current signal inductors due to its heavy-gauge wire and robust core structure.

Replacement Considerations

Publicly confirmed substitute part numbers include IH10BQ680K and IH10EB680K from Vishay Dale. These alternatives offer similar inductance and current ratings but may differ in physical dimensions or mounting characteristics.
