ALFT-03A-7

Overview

The ALFT-03A-7 is a common mode filter choke manufactured by Abracon LLC. It features a rated current of 0.8 A and a maximum DC resistance of 800 mOhm. The component provides an inductance of 7 mH at 1 kHz. It utilizes a radial through-hole mounting style with dimensions of 18 mm width, 23.9 mm length, and 21.6 mm height. The device operates within a temperature range of -25°C to +85°C.

Feature Summary

• Provides common mode noise suppression for AC line applications
• Radial through-hole construction for PCB integration
• RoHS compliant manufacturing

Applications

• AC power line filtering
• EMI suppression in electronic equipment
• Common mode noise reduction in power supplies

Procurement Notes

Verify the specific suffix '7' indicates the 7 mH inductance variant. Confirm the 0.8 A current rating matches system requirements. Ensure the radial lead configuration fits the target PCB footprint. Check RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when a 7 mH common mode choke is required for AC lines. The 0.8 A rating suits low-to-medium power applications. Verify that the physical dimensions fit the enclosure constraints. Consider the operating temperature range for environmental suitability.

Part Context

This part belongs to the ALFT series of common mode chokes from Abracon. The series includes variants with different inductance values and current ratings. The ALFT-03A designation typically refers to the case size and lead configuration used across multiple inductance options within the product family.

Replacement Considerations

Direct substitutes must match the 7 mH inductance, 0.8 A current rating, and 800 mOhm DCR. Verify identical physical dimensions for PCB compatibility. Ensure equivalent common mode rejection performance and temperature stability.
