MEM2012F25R0T001

Overview

The MEM2012F25R0T001 is a surface-mount EMI filter circuit manufactured by TDK Corporation. It features a Pi-filter topology designed for signal line protection. The component has a cutoff frequency of 25 MHz and operates at a maximum voltage of 12 V with a current rating of 200 mA. It includes a capacitance value of 90 pF. The physical dimensions are 2.00 mm in length, 1.25 mm in width, and 1.00 mm in height, corresponding to the 0805 package size.

Feature Summary

• Integrates a three-terminal Pi-filter structure for effective noise suppression on signal lines.
• Provides targeted attenuation at frequencies above 25 MHz to protect sensitive electronics.
• Utilizes a compact surface-mount design suitable for high-density PCB layouts.

Applications

• Signal line filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• EMI reduction in industrial control interfaces

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing details may evolve. Confirm that the 0805 footprint matches your PCB design constraints. Ensure the 12V rating and 200mA current limit align with your circuit requirements. Check for RoHS compliance status if required by your regional regulations. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when space is limited and a 25 MHz cutoff frequency is appropriate for the application. The 12V rating suits low-voltage logic and communication lines. Consider the 90 pF capacitance impact on signal integrity before implementation. Compare against other Pi-filters if higher current or different voltage ratings are needed.

Part Context

This part belongs to TDK's MEM2012F series of EMI filters. These components are engineered for suppressing electromagnetic interference in compact consumer and industrial electronics. The series offers various cutoff frequencies and capacitance values within the same 0805 footprint family.

Replacement Considerations

Direct substitutes must match the 25 MHz cutoff, 12V rating, and 0805 package. Verify equivalent capacitance and current handling capabilities. Cross-reference with other manufacturers offering similar Pi-filter configurations in SMD packages.
