Overview
The TDK ACM2012H-900-2P-T03 is a two-line surface mount common mode filter designed for high-speed differential and general signal lines. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 qualification. The component exhibits an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 300 mA. Its physical dimensions are 2.0 mm in length, 1.2 mm in width, and 1.3 mm in height, conforming to the 0805 (2012 metric) package standard.
Feature Summary
- Provides excellent common mode impedance and noise suppression capabilities
- Engineered specifically for high-speed differential signal lines
- Constructed in a compact surface mount case for space-constrained designs
Applications
- High-speed differential signal line filtering
- General signal line noise suppression
- Automotive electronic systems requiring AEC-Q200 components
Procurement Notes
Verify that the specific suffix 'T03' matches the required tape and reel quantity for your assembly line configuration. Confirm that the 300 mA current rating aligns with the operational requirements of the target circuit to ensure reliable performance under load conditions.
Selection Notes
Select this component when low inductance and high-frequency noise attenuation are critical for signal integrity. The AEC-Q200 certification makes it suitable for automotive applications where reliability standards are stringent. Ensure the 0805 footprint fits the available PCB real estate compared to larger packages.
Part Context
This part belongs to the TDK ACM series of common mode chokes and filters. The series offers various impedance values and current ratings across different package sizes, including 0805, 1008, and larger formats. These components are widely used in EMI suppression for digital communication interfaces and power lines.
Replacement Considerations
The ACM2012-900-2P-T001 is a related variant within the same series. Verify if the higher current rating of 400 mA in the T001 version is acceptable or if the 300 mA limit of the T03 version is sufficient for the application.
