MEA1210LD120T001

Overview

The MEA1210LD120T001 is a second-order LC low-pass EMI filter manufactured by TDK Corporation. Designed for surface mount applications, this component features a dual-channel configuration with a capacitance of 12 pF and a cutoff frequency of 410 MHz. It operates within a rated voltage of 6.3 V and supports a maximum current of 100 mA. The device is housed in a compact 1210 metric package (1.2 mm x 1.0 mm x 0.5 mm) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides second-order low-pass filtering characteristics for effective electromagnetic interference suppression
• Features a dual-channel L-type array design suitable for differential or parallel data line protection
• Incorporates magnetic shielding to enhance attenuation performance and reduce cross-talk

Applications

• High-frequency data lines in mobile devices
• Electromagnetic compatibility (EMC) filtering for portable electronics
• Signal integrity protection in compact consumer hardware

Procurement Notes

Verify the specific suffix and revision code against official TDK documentation to ensure exact electrical matching. Confirm RoHS compliance status as required by regional regulations. Check availability status, as some sources indicate potential discontinuation or limited stock for this specific part number. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when designing circuits requiring sharp attenuation above 410 MHz for 12 pF capacitance loads. Ensure the PCB layout accommodates the 1210 footprint dimensions. Verify that the 100 mA current rating meets the peak operational demands of the target data lines. Consider the -40°C to +85°C temperature range against the environmental conditions of the final assembly.

Part Context

This component belongs to TDK's MEA series of L-type array EMC filters. These components are engineered for high-density applications where space constraints limit the use of larger discrete filters. The series utilizes advanced magnetic materials to achieve superior noise suppression in minimal footprints, catering to the shrinking form factors of modern electronic devices.

Replacement Considerations

Direct substitutes may include other TDK models from the same series with adjusted capacitance values, such as the MEA1210LD220T001. Cross-referencing with third-party manufacturers requires careful verification of cutoff frequencies and physical dimensions to maintain circuit performance and board compatibility.
