ALFT-04-5

Overview

The Abracon ALFT-04-5 is a common mode filter designed for PCB mounting. It features radial termination and operates within a temperature range of -40°C to +125°C. The component provides an inductance of 2 mH with a tolerance of 20%. It supports a maximum DC current of 4 A and exhibits a maximum DC resistance of 13 mohms. The physical length is specified as 34 mm.

Feature Summary

• Radial leaded construction for through-hole PCB integration
• High current handling capability up to 4 amperes
• Low impedance design with minimal DC resistance

Applications

• Common mode noise suppression in power lines
• EMI filtering for electronic equipment input stages
• Signal integrity protection in industrial control systems

Procurement Notes

Verify component status carefully as the ALFT-04-5 is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market sources. Ensure that any replacement components meet the original electrical specifications, including inductance, current rating, and physical dimensions, to maintain system compatibility and performance standards.

Selection Notes

Select this component when a robust common mode choke with high current capacity is required for through-hole applications. The 2 mH inductance offers effective noise attenuation at lower frequencies. Consider the 13 mohm DC resistance for efficiency calculations in power supply designs. Verify thermal management requirements given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the ALFT series of common mode filters from Abracon. These components are engineered for general-purpose EMI suppression. The series typically includes various inductance values and current ratings to suit different circuit requirements. The ALFT-04-5 specifically targets applications needing moderate inductance with significant current handling capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements must be sourced based on matching electrical parameters such as 2 mH inductance, 4 A current rating, and compatible package dimensions.
