MEA1210D501R

Overview

The TDK MEA1210D501R is a second-order LC EMI filter designed for surface-mount applications. It features a low-pass configuration with two channels, rated for a maximum current of 100 mA and a voltage of 10V. The component has a cutoff frequency of 500 MHz and provides attenuation of 20 dB at frequencies between 1.5 GHz and 3 GHz. It is housed in a compact 0504 (1210 metric) package measuring 1.20mm x 1.00mm x 0.60mm. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Dual-channel low-pass LC filtering architecture
• Compact 0504 surface-mount footprint
• High attenuation performance in high-frequency bands

Applications

• Data lines for mobile devices

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus or secondary market sources rather than direct factory orders. Confirm RoHS3 compliance status and check for valid replacement part numbers from the same series before finalizing procurement plans due to end-of-life status.

Selection Notes

Select this component only if the specific 500 MHz cutoff frequency and 100 mA current rating align with the circuit requirements. Ensure the design accommodates the 0504 package dimensions and surface-mount mounting type. Verify that the dual-channel configuration meets the signal line needs, noting that ESD protection is not included in this specific filter variant.

Part Context

The MEA1210D501R belongs to the TDK MEA series of EMI filters. These components are engineered for noise suppression in high-speed data transmission lines. The series utilizes LC technology to provide effective interference reduction while maintaining signal integrity in compact electronic assemblies.

Replacement Considerations

Consult TDK official documentation for confirmed substitute part numbers within the MEA series. No public cross-reference substitutes are verified in the provided source material.
