Overview
The TDK ACM2012E-900-2P-T01 is a surface-mount common mode filter designed for high-speed differential and general signal lines. It features an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 300 mA. The component has a maximum DC resistance of 350 mOhms and operates within a temperature range of -40°C to +85°C. Its compact 0805 (2012 metric) package measures 2.0 mm in length, 1.2 mm in width, and 1.1 mm in height. Rated for 50 VDC, it meets AEC-Q200 automotive qualification standards.
Feature Summary
- Designed specifically for suppressing common mode noise on high-speed differential signal lines and general signal lines.
- Compact horizontal surface mount footprint suitable for space-constrained PCB layouts.
- Automotive-grade reliability certified under the AEC-Q200 standard.
Applications
- High-speed data interface protection
- General signal line noise suppression
- Automotive electronic systems
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm electrical tolerances and packaging details. Ensure compatibility with reflow soldering profiles specified for this component type. Confirm that the 300 mA rated current aligns with your circuit's operational requirements to prevent saturation or overheating during normal use.
Selection Notes
Select this component when filtering common mode interference on signal lines requiring low insertion loss and minimal DC resistance. The 90 Ohm impedance at 100 MHz targets specific frequency ranges; verify this matches the noise spectrum. Consider the 300 mA current rating and 350 mOhm DCR to ensure signal integrity is maintained without excessive voltage drop or thermal issues in the target application.
Part Context
This part belongs to the TDK ACM2012 series of common mode chokes. These components are engineered for signal lines rather than power lines, distinguishing them from higher-current variants in the same family. The 'E' suffix typically denotes specific automotive or enhanced reliability characteristics within the product line.
Replacement Considerations
Direct substitutes include ACM2012-900-2P-T001 and ACM2012-900-2P-T002. Verify that replacement parts match the 90 Ohm impedance at 100 MHz and the 300 mA current rating. Check if the alternative suffixes maintain the same AEC-Q200 qualification status if automotive compliance is required.
