Overview
The ACM2012D-900-2P-TL00 is a surface-mount common mode filter designed for high-speed differential signal lines. It features a 0805 (2012 metric) package with dimensions of 2.00mm length, 1.20mm width, and a maximum height of 1.30mm. The component provides a common mode impedance of 90 Ohms at 100 MHz and supports a rated current of 300 mA. It operates within a temperature range of -40°C to +85°C and carries AEC-Q200 qualification.
Feature Summary
- Designed specifically for suppressing electromagnetic interference on high-speed differential signal lines
- Compact 0805 surface mount footprint suitable for space-constrained PCB layouts
- Qualified for automotive applications under the AEC-Q200 standard
Applications
- High-speed differential signal line filtering in automotive electronics
- Noise suppression for general signal lines in communication equipment
- EMI reduction in portable electronic devices requiring compact filters
Procurement Notes
Verify the specific suffix TL00 against official TDK documentation to confirm tape and reel specifications. Ensure compatibility with automated pick-and-place equipment regarding the 0805 package dimensions. Confirm that the 300 mA rated current meets the design requirements for the target signal line application.
Selection Notes
Select this component when a low-profile 0805 common mode choke is required for high-speed data lines. The 90 Ohm impedance at 100 MHz targets typical USB or HDMI noise frequencies. Consider the 300 mA current rating to ensure it does not saturate during normal operation. Verify thermal performance within the -40°C to +85°C operating range.
Part Context
This part belongs to the TDK ACM2012 series of surface mount common mode chokes. The series offers various impedance values and current ratings in a standardized 0805 package. These components are engineered to minimize size while providing effective noise suppression for sensitive digital interfaces.
Replacement Considerations
Check for ACM2012D-900-2P-T00 as a potential variant with similar electrical characteristics but different packaging or tolerance specifications. Verify pinout and impedance curves before substitution.
