ACMP-7038-701-T

Overview

The Abracon ACMP-7038-701-T is a surface-mount common mode choke designed for two-line signal protection. It features a ferrite core and shielded construction to minimize electromagnetic interference. The component operates within a temperature range of -40°C to +125°C. Key electrical specifications include an impedance of 700 ohms at 100 MHz, a maximum DC current rating of 4A, and a maximum DC resistance of 15 milliohms. The physical dimensions are 7mm in length, 6mm in width, and 3.8mm in height.

Feature Summary

• Shielded design reduces external magnetic field interference
• High saturation current capability supports robust signal integrity
• Compact surface-mount footprint facilitates automated PCB assembly

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by your manufacturing process. Confirm that the 4A current rating aligns with your circuit's peak load requirements. Ensure the 700 Ohm impedance matches the target frequency spectrum for effective common mode noise attenuation. Cross-reference the RoHS compliance status with your environmental regulations.

Selection Notes

Select this component when shielding is critical to prevent crosstalk from adjacent traces or external sources. The 4A rating suits applications with moderate current loads but high noise sensitivity. Compare against unshielded alternatives if space constraints allow for larger, lower-cost chokes without shielding requirements. Validate thermal performance under continuous operation at elevated ambient temperatures.

Part Context

This part belongs to the ACMP-7038 series of common mode filters. It shares the same physical package and general form factor with variants like the ACMP-7038-700-T, which offers different impedance characteristics. The series is engineered for compact electronic designs requiring reliable EMI suppression in limited board real estate.

Replacement Considerations

Direct substitutes may include other Abracon parts within the ACMP-7038 family with matching impedance and current ratings. Verify pin compatibility and mechanical dimensions before replacing with components from different manufacturers.
