Overview
The ACM2012-201-2P-T001 is a surface-mount common mode filter manufactured by TDK Corporation, designed for high-speed differential and general signal lines. It features a two-channel configuration within an 0805 (2012 metric) package measuring 2.0 mm in length, 1.2 mm in width, and 1.3 mm in maximum height. The component provides an impedance of 200 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 200 mA with a maximum DC resistance of 900 mOhms. Rated for a DC voltage of 20V, it operates reliably across a temperature range of -40°C to +85°C and holds AEC-Q200 qualification.
Feature Summary
- Provides effective noise suppression for high-speed differential and general signal lines through common mode filtering.
- Features a compact 0805 surface-mount footprint suitable for space-constrained printed circuit board layouts.
- Includes AEC-Q200 qualification to ensure reliability and durability for automotive electronic applications.
Applications
- Noise suppression in automotive infotainment systems

Procurement Notes
Verify the specific part number ACM2012-201-2P-T001 against official manufacturer documentation to confirm availability and specifications. Ensure that the selected component meets the required impedance and current ratings for the target application. Check for any RoHS compliance status and packaging options such as cut tape or reel configurations directly from authorized distributors or the manufacturer's catalog.
Selection Notes
Select this component when designing circuits requiring common mode noise reduction for signal lines carrying up to 200 mA. The 200 Ohm impedance at 100 MHz makes it suitable for suppressing electromagnetic interference in digital communication interfaces. Consider the 0805 package size for compatibility with standard SMT assembly processes and verify thermal operating limits align with the system environment.
Part Context
This component belongs to the TDK ACM series of common mode filters, which are engineered for EMI suppression in various electronic devices. The ACM series offers multiple package sizes and impedance values to accommodate different signal integrity requirements. The ACM2012 variant specifically targets applications where compact form factors are essential while maintaining robust noise filtering performance.
Replacement Considerations
Consult official TDK documentation for verified substitute part numbers within the ACM series. Cross-reference impedance, current rating, and package dimensions to ensure functional equivalence. No public confirmed substitutes are listed in the provided data.
