ATCA-02-290M-V

Fixed Inductors Overview

The ATCA-02-290M-V is a fixed toroidal inductor from Abracon LLC's ATCA series, designed for low electromagnetic interference applications. It features an unshielded construction with radial vertical mounting and an open core design. The component provides an inductance of 29 µH with a tolerance of ±20%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 20 mOhms. The unit operates within a temperature range of -40°C to +105°C.

Fixed Inductors Feature Summary

• Unshielded toroidal core structure for low EMI performance
• Radial vertical lead style for through-hole mounting
• High current handling capability up to 4 A
• Wide operating temperature range suitable for industrial environments

Fixed Inductors Applications

• Power supply filtering circuits
• EMI suppression in electronic equipment
• General-purpose inductive components in power electronics

Fixed Inductors Procurement Notes

Verify the specific suffix (V or H) against the datasheet to confirm terminal pitch and mechanical dimensions, as these variants differ physically. Ensure the required inductance value and current rating align with circuit specifications before ordering. Confirm that the unshielded nature meets the system's EMI requirements.

Fixed Inductors Selection Notes

Select this component when a 29 µH inductance with 4 A current capacity is required in a vertical through-hole package. Consider the unshielded design implications for nearby sensitive components. Verify that the 20 mOhm DCR fits the efficiency constraints of the application.

Fixed Inductors Part Context

This part belongs to Abracon's ATCA series of low EMI toroidal inductors. The series offers various inductance values and current ratings in similar form factors. The ATCA-02-290M-V specifically denotes the 29 µH variant with vertical leads, distinguishing it from horizontal lead options.

Fixed Inductors Replacement Considerations

Check for direct substitutes with identical 29 µH inductance, 4 A rating, and compatible physical dimensions. Verify that alternative manufacturers offer comparable DCR and temperature ratings. Ensure any replacement maintains the radial vertical mounting style if board space is constrained.
