ALFT-03A-6

Overview

The ALFT-03A-6 is a through-hole common mode choke manufactured by Abracon LLC. It features an inductance of 10 mH at a test frequency of 1 kHz and supports a maximum DC current of 700 mA. The component has a maximum DC resistance of 800 mOhms and operates within a temperature range of -25°C to 85°C. Designed for two-line applications, it utilizes a vertical package with four PC pins.

Feature Summary

• Provides common mode noise suppression for two-line circuits
• Supports high current handling up to 700 mA
• Utilizes through-hole mounting for secure PCB attachment

Applications

• Power supply input filtering
• Signal line noise reduction
• EMI suppression in electronic equipment

Procurement Notes

Verify the specific part number ALFT-03A-6 against official Abracon documentation to confirm electrical parameters such as 10 mH inductance and 700 mA current rating. Ensure compatibility with through-hole assembly processes and verify operating temperature requirements match application needs before procurement.

Selection Notes

Select this component when designing circuits requiring common mode noise filtration for lines carrying up to 700 mA. Consider the 800 mOhm DC resistance impact on voltage drop and the 10 mH inductance value for target noise frequencies. Ensure the physical dimensions fit the available board space for vertical mounting.

Part Context

This component belongs to the ALFT series of common mode chokes from Abracon LLC. The series offers various inductance values and current ratings tailored for different filtering requirements. The ALFT-03A-6 specifically targets applications needing moderate inductance with higher current capacity compared to lower-rated variants in the same family.

Replacement Considerations

Consult official Abracon documentation for verified substitute part numbers within the ALFT series or equivalent components from other manufacturers that meet the 10 mH @ 1 kHz, 700 mA, and 800 mOhm specifications.
