DC630R-274K

Fixed Inductors Overview

The DC630R-274K is a fixed power inductor from the API Delevan DC630R series, designed for high-current applications. It features a 270 µH nominal inductance with a tolerance of ±10%. The component supports a saturation current of 2.09 A and has a maximum DC resistance of 225 mΩ. Constructed as an unshielded drum core wirewound inductor, it utilizes a radial vertical cylinder package suitable for through-hole mounting.

Fixed Inductors Feature Summary

• High current handling capability with 2.09 A rating
• Unshielded drum core construction for specific magnetic field requirements
• Radial vertical termination style for standard PCB mounting

Fixed Inductors Applications

• Power line chokes
• DC-DC converter filtering
• Power supply input/output stages

Fixed Inductors Procurement Notes

Verify the exact inductance value of 270 µH and the DC resistance limit of 225 mΩ against design specifications. Confirm that the unshielded nature of the drum core aligns with electromagnetic interference constraints. Ensure the radial through-hole package fits the target PCB footprint and mechanical clearance requirements before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a high-current power choke is required for power line filtering. The unshielded design may necessitate careful layout to manage magnetic coupling. Compare the 2.09 A saturation current against peak load demands to ensure stable operation under all conditions without core saturation.

Fixed Inductors Part Context

This part belongs to the DC630R series of high-current power line chokes manufactured by API Delevan. The series offers various inductance values tailored for robust power electronics applications. The DC630R-274K specifically targets circuits requiring significant current handling with moderate inductance.

Fixed Inductors Replacement Considerations

Cross-reference other parts within the DC630R series or equivalent high-current radial inductors from API Delevan. Verify that substitute components match the 270 µH inductance, 2.09 A current rating, and 225 mΩ resistance limits to maintain circuit performance.
