MEA2010LD220

Overview

The MEA2010LD220 is a surface-mount LC EMI filter array manufactured by TDK Corporation. It features a 4-channel configuration with a capacitance value of 22pF per channel. The component is designed for high-frequency noise suppression, exhibiting a cutoff frequency of 240MHz. It supports a maximum current rating of 100mA and operates within a temperature range of -40°C to +85°C. The physical package corresponds to the 0804 (2010 Metric) footprint, suitable for compact electronic designs requiring efficient signal line protection.

Feature Summary

• Provides multi-channel EMI/RFI noise suppression through integrated LC filtering networks
• Designed specifically for protecting data lines in mobile devices against electromagnetic interference
• Utilizes a compact surface-mount array structure to optimize board space utilization

Applications

• Data lines for mobile devices
• High-speed digital signal interfaces requiring noise attenuation
• Consumer electronics with sensitive communication circuits

Procurement Notes

Verify the specific datasheet version from TDK Corporation to confirm electrical characteristics and mechanical dimensions. Ensure compatibility with the target PCB footprint and soldering profile. Check RoHS compliance status as indicated in official documentation. Confirm that the 240MHz cutoff frequency meets the system's EMI requirements. Validate the 100mA current rating against the application's operational load.

Selection Notes

Select this component when multi-channel filtering is required for low-capacitance data lines. The 22pF value offers minimal signal distortion while providing effective high-frequency attenuation. Consider the 0804 package size for space-constrained layouts. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare performance against single-channel filters if fewer lines require protection.

Part Context

This part belongs to TDK's MEA series of EMI/RFI filters, which are passive components used for noise suppression in electronic circuits. These filters typically integrate capacitors and inductors into a single package to provide common-mode or differential-mode filtering. The MEA series is widely used in portable electronics and automotive applications where space efficiency and signal integrity are critical design constraints.

Replacement Considerations

Consult TDK's official substitution guide for equivalent parts within the MEA series. Verify that any alternative maintains the same 22pF capacitance and 240MHz cutoff frequency. Ensure the replacement matches the 0804 footprint and 100mA current rating. Confirm thermal performance aligns with the original specification.
