ACMS-Q4526C-220-T

Overview

The Abracon ACMS-Q4526C-220-T is a surface-mount common mode choke designed for signal line protection. It features an inductance of 22 µH at 100 kHz, with a maximum DC current rating of 310 mA and a maximum DC resistance of 800 mOhms. The component operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive standards. Its compact footprint supports automated assembly processes.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Complies with AEC-Q200 automotive qualification requirements
• Utilizes RoHS compliant and lead-free construction

Applications

• Automotive infotainment system signal filtering
• High-speed data interface noise attenuation
• Electronic control unit (ECU) peripheral protection

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm that the 800 mOhm DC resistance aligns with circuit loss requirements. Ensure the 310 mA current rating exceeds the operational peak current to prevent saturation or thermal issues during normal operation.

Selection Notes

Select this component when signal integrity requires 22 µH common mode impedance at low frequencies. The 310 mA current limit suits low-power signal lines rather than power delivery paths. Verify the 4.5 mm length fits within the designated PCB layout constraints for the target application.

Part Context

This part belongs to the ACMS-Q4526C series of automotive-grade common mode chokes. It is distinct from power inductors like the ASPI-4020S series, which serve different functional roles in power conversion circuits. The Q4526C designation specifies the physical package dimensions and mounting style.

Replacement Considerations

Direct substitutes must match the 22 µH inductance, 310 mA current rating, and 800 mOhm resistance. Verify equivalent AEC-Q200 certification if automotive reliability is required. Check mechanical compatibility with the existing footprint.
