MEM2012P25R0

Overview

The MEM2012P25R0 is a third-order low-pass LC (Pi) EMI filter manufactured by TDK Corporation. It operates within a temperature range of -40°C to 85°C and features a rated voltage of 12V. The component is designed for surface mount technology in an 0805 (2012 Metric) package with three pads. It supports a maximum current of 200 mA and provides filtering at a cutoff frequency of 25 MHz. This device is intended for data line protection in mobile devices.

Feature Summary

Provides third-order low-pass filtering for effective EMI suppression
Utilizes LC Pi network topology for signal integrity
Designed for compact surface mount applications

Applications

Data lines for mobile devices
EMI suppression in portable electronics
Signal filtering in compact circuit boards

Procurement Notes

Verify component status as the MEM2012P25R0 is listed as obsolete by major distributors. Confirm availability through secondary market channels or authorized surplus dealers. Ensure compatibility with existing PCB layouts before procurement, as new production may not be guaranteed. Cross-reference datasheets for any potential revisions in pinout or electrical characteristics if sourcing from non-original manufacturers.

Selection Notes

Select this component for applications requiring a 25 MHz cutoff frequency in an 0805 footprint. Consider the 200 mA current rating and 12V voltage limit during design. Evaluate thermal performance within the specified -40°C to 85°C operating range. Verify that the LC Pi topology meets the specific noise attenuation requirements of the target data line.

Part Context

This part belongs to the TDK MEM series of EMI filters. The series offers various configurations for suppressing electromagnetic interference in high-speed digital circuits. The MEM2012P25R0 specifically addresses noise in mobile device data lines using a compact SMD form factor suitable for space-constrained designs.
