ACM-0603-181-T

Overview

The ACM-0603-181-T is a surface-mount common mode choke from Abracon LLC, designed for signal line EMI filtering. It features a 180 Ohm impedance at 100 MHz and supports a DC current rating of 500 mA. The component exhibits a maximum DC resistance of 210 mOhm. It operates within a temperature range of -40°C to +85°C and utilizes a compact 0603 package footprint.

Feature Summary

• Provides effective common mode noise suppression for high-speed data lines
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low DC resistance minimizes signal attenuation in power or data paths

Applications

• High-speed serial interface protection
• USB port filtering
• HDMI signal line conditioning

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official Abracon datasheet before procurement. Confirm that the 0603 package dimensions align with your PCB footprint constraints. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when low insertion loss and moderate current handling are required for differential pairs. The 180 Ohm impedance offers a balance between noise attenuation and signal integrity for standard digital interfaces. Consider the 0603 size for density optimization where larger packages are not feasible.

Part Context

This component belongs to Abracon's ACM-0603 series of common mode chokes. These devices are engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The series provides standardized footprints to facilitate design reuse across multiple product lines.

Replacement Considerations

Consult official distributor databases for direct cross-references. Verify pin compatibility and impedance curves before substituting.
