EXC-28CG900U

Common Mode Chokes Overview

The Panasonic EXC-28CG900U is a surface-mount common mode noise filter designed for high-speed data lines. It features a 90 Ohm impedance with a 25% tolerance and a maximum DC resistance of 1.75 Ohms. The component supports a maximum DC current of 130 mA and operates within a temperature range of -40°C to +85°C. Its compact SMD package measures 2mm in length, 1mm in width, and 0.5mm in height.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for high-speed data transmission lines
• Features low DC resistance to minimize signal loss and power consumption
• Utilizes a compact surface-mount footprint suitable for space-constrained PCB designs

Common Mode Chokes Applications

• USB interface circuits
• High-speed data line protection
• Portable electronic devices requiring EMI suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix 'CG' against official Panasonic documentation to confirm pin configuration and electrical characteristics. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm availability status as some distributors indicate scheduled obsolescence for this series.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise filtering for differential data lines. Consider the 130 mA current rating and 90 Ohm impedance for matching system requirements. Evaluate the small 0804-equivalent footprint for dense layout applications where standard chokes are too large.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of common mode noise filters. These components are engineered specifically for suppressing electromagnetic interference in high-speed digital interfaces. The series offers various impedance values and current ratings to suit different data bus speeds and power constraints.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the EXC series or equivalent offerings from other manufacturers that match the 90 Ohm impedance, 130 mA rating, and 2x1x0.5mm package dimensions. Verify pinout compatibility before substitution.
