Overview
The ALFT-09V-202 is a two-line common mode filter choke manufactured by Abracon LLC. It features an inductance of 2.0 mH with a maximum DC resistance (DCR) of 0.8 ohms and a rated RMS current (Ir) of 0.7 A. The component measures 16.5 x 11.5 x 17.0 mm and is supplied in bulk packaging. It is designed for through-hole mounting and provides high common mode impedance to suppress noise in digital signal lines.
Feature Summary
- Presents high common mode impedance for effective noise suppression
- Enables significant attenuation of high-frequency interference
- Compliant with RoHS and RoHS II standards
Applications
- Filtering common mode noise in USB, IEEE1394, and LVDS interfaces
- Digital audio and video equipment such as PDAs, DSCs, DVCS, and DVD players
- Noise reduction in digital cameras and scanners
Procurement Notes
Verify the obsolete status and end-of-life notification date before procurement planning. Confirm availability through authorized distributors or secondary markets. Ensure replacement components match the 2.0 mH inductance, 0.8 ohm DCR, and 0.7 A current rating specifications to maintain circuit performance integrity.
Selection Notes
Select this component for applications requiring robust common mode noise filtering in portable digital devices. The 0.7 A current rating suits low-power signal lines. Verify that the physical dimensions fit the PCB layout constraints. Consider the through-hole mounting style when designing the assembly process.
Part Context
This part belongs to the ALFT-09V series of common mode chokes from Abracon. The series offers various inductance values ranging from 0.5 mH to 10.0 mH. The ALFT-09V-202 specifically targets mid-range inductance requirements for consumer electronics. It shares the same physical footprint and mounting characteristics as other variants in the family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must evaluate alternative common mode chokes with matching electrical parameters (2.0 mH, 0.8 ohm DCR, 0.7 A) and mechanical dimensions.
