EXC-34CE201U

Common Mode Chokes Overview

The Panasonic EXC-34CE201U is a surface-mount common mode noise filter designed for high-frequency signal line protection. It features a 200 Ohm impedance at 100 MHz with a 25% tolerance, suitable for suppressing electromagnetic interference in compact electronic devices. The component supports a maximum DC current of 200 mA and maintains a low DC resistance of 1 Ohm to minimize signal loss. Housed in an unshielded 0806 (2.0 x 1.25 mm) package with a height of 0.5 mm, it operates reliably within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for high-speed data lines
• Compact surface-mount footprint enables dense PCB layout integration
• Low DC resistance ensures minimal impact on signal integrity

Common Mode Chokes Applications

• High-speed USB interface circuits
• HDMI and DisplayPort signal lines
• LVDS data transmission systems

Common Mode Chokes Procurement Notes

Verify the specific suffix and packaging configuration against the official Panasonic datasheet before ordering. Confirm that the required impedance tolerance and current ratings align with the target circuit design. Ensure compatibility with standard reflow soldering profiles for SMD components. Check for RoHS compliance status if required by regional regulations.

Common Mode Chokes Selection Notes

Select this component when space constraints require a small 0806 package size while maintaining adequate noise filtering performance. Consider the 200 mA current rating to ensure it exceeds the operational current of the protected signal line. Evaluate the 1 Ohm DC resistance to verify it meets the voltage drop requirements of the application.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of common mode chokes, which are engineered for EMI suppression in portable electronics and communication equipment. The series offers various impedance values and package sizes to accommodate different frequency ranges and physical layout requirements.

Common Mode Chokes Replacement Considerations

Consult the official Panasonic replacement guide or equivalent manufacturer datasheets for direct pin-compatible substitutes. Verify that alternative parts match the 200 Ohm impedance at 100 MHz and the 0806 package dimensions.
