ACMF-03-900-T

Overview

The Abracon ACMF-03-900-T is a surface-mount thin film common mode choke designed for high-frequency noise suppression. It operates with an impedance of 90 Ohms at 100 MHz and features a cutoff frequency of 2.1 GHz. The component supports a current rating of 100 mA with a typical DC resistance of 2.8 Ohms. Packaged in a compact SMD form factor, it provides effective common mode rejection for signal lines requiring EMI filtering.

Feature Summary

• Thin film construction for precise impedance characteristics
• High cutoff frequency for broadband noise attenuation
• Compact surface mount design for space-constrained PCBs

Applications

• High-speed data line filtering
• USB interface noise suppression
• HDMI signal integrity protection

Procurement Notes

Verify the specific suffix T against the manufacturer datasheet to confirm packaging and tape-and-reel specifications. Ensure the 100 mA current rating aligns with the target circuit requirements. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Selection Notes

Select this component when low capacitance and high impedance are required for differential pairs. The 90 Ohm impedance matches standard transmission line impedances. Evaluate the 2.8 Ohm DCR impact on signal loss. Consider the physical footprint compatibility during layout planning.

Part Context

This part belongs to the ACMF-03 series of thin film common mode filters from Abracon. These components utilize advanced thin film technology to achieve stable performance across temperature variations. The series is engineered for applications demanding reliable EMI suppression in compact electronic devices.

Replacement Considerations

Cross-reference with other ACMF-03 variants for different impedance values. Verify pinout compatibility if substituting with similar SMD chokes. Check electrical parameters such as cutoff frequency and current handling capabilities.
