Overview
The ALFT-03A-11 is a common mode filter choke from the Abracon ALFT series, designed for PCB mounting via radial through-hole termination. It features a ferrite core and provides an inductance of 2.1 mH at 1 kHz with a maximum DC current rating of 1.5 A. The component exhibits a maximum DC resistance of 600 milliohms. Operating within a temperature range of -25°C to +85°C, it measures 23.9 mm in length, 18 mm in width, and 21.6 mm in height.
Feature Summary
- Radial through-hole construction for standard PCB integration
- Ferrite core material for effective noise suppression
- Single-channel common mode filtering capability
Applications
- Commercial electronic equipment line filtering
- Industrial control system power input stages
- AC line filter applications designated for commercial use
Procurement Notes
Verify the specific suffix '11' against official Abracon documentation to confirm the 2.1 mH inductance and 1.5 A current rating. Ensure the procurement specification matches the required 600 milliohm DCR and thermal limits. Confirm that the application environment remains within the specified -25°C to +85°C operating range for reliable performance.
Selection Notes
Select this component when a single-channel common mode choke with 2.1 mH inductance is required for through-hole assembly. The 1.5 A current rating suits moderate power applications. Verify physical footprint compatibility with the 23.9 x 18 x 21.6 mm dimensions. Ensure the ferrite core characteristics align with the target frequency noise suppression requirements.
Part Context
This part belongs to the ALFT series of common mode chokes manufactured by Abracon LLC. These components are classified as Commercial-Off-The-Shelf (COTS) items suitable for general commercial and industrial environments. The series utilizes ferrite cores and offers various inductance and current ratings differentiated by alphanumeric suffixes.
Replacement Considerations
Cross-reference with other ALFT series variants such as ALFT-03A-13 for higher current capacity or different inductance values. Verify pinout and dimensional compatibility before substituting with generic common mode chokes.
