MEA1210LD220

Overview

The MEA1210LD220 is a surface-mount LC EMI filter manufactured by TDK Corporation. It features a second-order low-pass circuit topology designed for data line protection. The component provides a capacitance of 22 pF and supports a maximum operating frequency of 250 MHz. It is rated for a continuous current of 100 mA and operates within a voltage range up to 6.3 V. The device utilizes a 1210 metric package (0504 case) with two channels, ensuring compact integration into high-density printed circuit boards while maintaining signal integrity.

Feature Summary

• Second-order low-pass LC filter architecture for effective noise attenuation
• Dual-channel design supporting differential or single-ended data lines
• Compact 1210 surface-mount footprint for space-constrained applications

Applications

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

Procurement Notes

Verify the specific suffix codes against official TDK documentation to confirm exact capacitance tolerance and termination specifications. Ensure the selected variant matches the required RoHS compliance status for your manufacturing process. Cross-reference the datasheet parameters with your system's voltage and current requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring robust EMI suppression for low-voltage data lines. The 22 pF capacitance value offers a balance between filtering performance and signal transmission speed. Consider the 1210 package size relative to available PCB real estate and ensure the 100 mA current rating exceeds the operational load of the protected line.

Part Context

This part belongs to TDK's MEA series of surface-mount LC filters. These components are engineered specifically for suppressing electromagnetic interference in sensitive electronic systems. The series emphasizes miniaturization without compromising filtering efficiency, making it suitable for modern consumer electronics and industrial control systems where space is limited.

Replacement Considerations

Consult TDK's official cross-reference tools for verified substitutes. Ensure any replacement maintains identical package dimensions, pin configuration, and electrical ratings to guarantee mechanical and functional compatibility.
