ALFT-04-6

Overview

The ALFT-04-6 is a two-line common mode choke manufactured by Abracon LLC, designed for through-hole PCB mounting. It features an inductance of 3 mH at a test frequency of 1 kHz with a tolerance of 20%. The component supports a maximum DC current of 3.7 A and exhibits a maximum DC resistance of 16 mOhms. It operates within a temperature range of -40°C to +125°C and provides a voltage withstand capability of 2 kV. The physical dimensions are approximately 31 mm in height, 21.6 mm in width, and 18 mm in length.

Feature Summary

• Provides effective common mode noise suppression for dual-line signal paths
• Engineered for robust performance across wide industrial temperature ranges
• Utilizes through-hole radial termination for secure PCB integration

Applications

• Signal line filtering in electronic circuits
• Noise reduction in power supply input stages
• EMI suppression in communication interfaces

Procurement Notes

Verify the specific manufacturing status as this component may be discontinued or subject to limited availability. Confirm that the 2 kV voltage withstand rating meets the insulation requirements of the target application. Ensure the 3.7 A current rating aligns with the operational load to prevent saturation. Check for updated datasheets regarding any design changes or end-of-life notifications from Abracon LLC before finalizing procurement plans.

Selection Notes

Select this component when a 3 mH inductance value is required for common mode noise attenuation at 1 kHz. The 16 mOhm DC resistance indicates low insertion loss for high-current applications up to 3.7 A. The through-hole package is suitable for prototyping or environments requiring mechanical stability. Compare against other ALFT series variants if different inductance or current ratings are needed.

Part Context

The ALFT-04-6 belongs to the ALFT series of common mode chokes from Abracon LLC. This series includes various models with differing inductance values and current ratings, such as the ALFT-04-3 and ALFT-04-7. These components are standardized for use in filtering applications where common mode interference needs to be mitigated without affecting differential signals significantly.
