Overview
The Abracon ACMP-1264-272-T is a surface-mount common mode choke designed for signal line filtering. It features a two-line configuration with an impedance of 2,700 ohms at 100 MHz and a maximum DC current rating of 1.5 A. The component exhibits a low DC resistance of 50 milliohms. It operates within a temperature range of -40°C to +85°C and utilizes SMD/SMT termination for PCB mounting.
Feature Summary
- Provides effective common mode noise suppression for differential signal lines
- Compact surface-mount design facilitates automated assembly and space-constrained layouts
- Low DC resistance minimizes power loss and voltage drop in the signal path
Applications
- High-speed data interface filtering
- USB port protection circuits
- Ethernet signal line conditioning
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging if bulk handling is required. Confirm RoHS compliance status through the official manufacturer datasheet prior to integration. Ensure the selected footprint matches the physical dimensions specified in the mechanical drawings to prevent soldering defects during reflow processes.
Selection Notes
Select this component when high impedance at 100 MHz is critical for EMI reduction. The 1.5 A current rating suits moderate signal loads. Compare against series variants like ACMP-1264-102-T for lower impedance needs or ACMP-1264-273-T for higher attenuation requirements while maintaining similar form factors.
Part Context
This part belongs to the Abracon ACMP-1264 series of common mode chokes. The series offers various impedance and current ratings tailored for different signal integrity applications. The 1264 designation typically refers to the specific package size and winding configuration optimized for surface-mount technology.
Replacement Considerations
Direct substitutes include other Abracon ACMP-1264 series parts with matching impedance and current ratings. Cross-brand replacements require verifying identical impedance curves, current saturation levels, and physical footprint compatibility.
