ALFT-09V-501

Overview

The ALFT-09V-501 is a two-line common mode choke from the Abracon ALFT-09V series, designed for through-hole mounting. It features a minimum inductance of 0.5 mH and a maximum DC resistance (DCR) of 0.2 Ω. The component supports a rated RMS current (Ir) of 1.4 A and undergoes a hipot test of 1500 V RMS. Its physical dimensions are 16.50 mm in length, 11.50 mm in width, and a maximum height of 17.00 mm. The device operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

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

Applications

• Filtering common mode noise in USB interfaces
• Noise suppression for IEEE1394 connections
• Signal integrity enhancement for LVDS lines
• Protection in digital audio and video equipment such as PDAs, DSCs, DVCs, and DVD players

Procurement Notes

Verify component authenticity and datasheet version upon acquisition. Confirm that the received part matches the ALFT-09V-501 designation, specifically checking the 0.5 mH inductance and 1.4 A current rating against the official Abracon specifications. Ensure handling procedures account for the through-hole package type and verify compliance documentation if required for your specific manufacturing process.

Selection Notes

Select this component when designing circuits requiring common mode noise reduction for low-current signal lines. The 0.5 mH inductance and 1.4 A current rating make it suitable for data transmission lines like USB and LVDS where moderate impedance is needed without excessive voltage drop. Consider the 16.5 x 11.5 mm footprint for PCB layout constraints and ensure the operating temperature range of -40°C to 125°C aligns with the environmental conditions of the final application.
