ALFT-09V-103

Overview

The ALFT-09V-103 is a common mode line filter manufactured by Abracon LLC, designed for signal line noise suppression. It features an inductance of 10.0 mH with a maximum DC resistance (DCR) of 3.6 Ohms and a rated current (Ir) of 0.3 Arms. The component utilizes a vertical through-hole package with four pins, measuring 16.5 mm in length, 11.5 mm in width, and 17.0 mm in height. It operates within a temperature range of -40°C to +125°C and meets RoHS compliance standards.

Feature Summary

• Presents high common mode impedance for effective noise attenuation
• Enables significant noise suppression at high frequencies
• Compliant with Pb-free and RoHS/RoHS II regulations

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 suppression in digital cameras and scanners

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be obsolete or discontinued. Confirm that the required electrical parameters, including the 10.0 mH inductance and 0.3 Arms current rating, align with the design specifications. Ensure compatibility with the vertical through-hole mounting style and verify that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component when high-frequency common mode noise suppression is required for low-current signal lines. The 10.0 mH inductance provides substantial filtering capability, while the 0.3 Arms rating suits data lines with lower current demands. Consider the physical dimensions and through-hole mounting constraints during PCB layout. Compare against other ALFT-09V series variants if different inductance or current ratings are needed.

Part Context

The ALFT-09V-103 belongs to the ALFT-09V series of common mode chokes from Abracon. This series offers various inductance values ranging from 0.5 mH to 10.0 mH, allowing designers to choose components based on specific noise frequency and current requirements. All members share similar physical footprints and mounting styles, facilitating standardized design processes across different product lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the ALFT-09V-103 is listed as obsolete, engineers should consult Abracon directly for potential end-of-life notifications or recommended alternative components within the same family or newer generations.
