MEA1608LC040T001

Overview

The MEA1608LC040T001 is a 3-terminal EMI/RFI filter from TDK, designed for signal line protection. It features a low-pass LC network configuration with four channels in a single array package. The component has a capacitance of 4 pF and supports a maximum current of 100 mA at a voltage rating of 6.3 V. It operates within a frequency range of 210 to 310 MHz. The physical dimensions are 1.6 mm length, 0.8 mm width, and 0.5 mm height, conforming to the 0603 (1608 Metric) surface-mount footprint.

Feature Summary

• Provides effective EMI suppression through a second-order low-pass LC filter architecture.
• Integrates four independent filtering channels into a compact single-array package.
• Utilizes 3-terminal technology to minimize parasitic inductance for high-frequency performance.

Applications

• Protection of high-speed digital signal lines in consumer electronics
• EMI suppression in automotive infotainment and comfort systems
• Filtering noise on data interfaces in portable devices

Procurement Notes

Verify the complete part number including suffixes to ensure correct capacitance tolerance and termination type. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for specific tape-and-reel packaging requirements if automated assembly is planned. Ensure the selected variant matches the required operating temperature range for the target application environment.

Selection Notes

Select this component when space-constrained designs require multi-channel filtering in a standard 0603 footprint. The 4 pF capacitance value is suitable for high-speed signals where minimal loading is critical. Consider the 100 mA current rating for power integrity in low-power signal paths. Evaluate the 210-310 MHz operational range against the specific noise frequencies present in the circuit design.

Part Context

This component belongs to TDK's MEA series of 3-terminal filters, which are engineered for superior high-frequency attenuation compared to standard 2-terminal capacitors. The series utilizes specialized internal structures to reduce equivalent series inductance (ESL), making it ideal for suppressing electromagnetic interference in dense PCB layouts where signal integrity is paramount.

Replacement Considerations

Cross-reference with other TDK MEA series variants such as MEA1608LC020 or MEA1608LC060 for different capacitance values. Verify pin compatibility and mechanical dimensions before substituting with components from other manufacturers to ensure proper solder joint formation and electrical performance.
