Overview
The ACM2012H-900-2P-T06 is a surface-mount common mode choke from the TDK ACM-H series, designed for high-speed differential signal lines. It features a 90 Ohm impedance at 100 MHz and supports a maximum DC current of 300 mA with a rated voltage of 50 VDC. The component utilizes an AEC-Q200 qualified construction, ensuring reliability in automotive applications. Its compact 0805 (2012 metric) package measures 2.0 mm x 1.2 mm x 1.2 mm, facilitating dense PCB layouts while providing effective electromagnetic interference suppression.
Feature Summary
- Engineered specifically for high-speed differential signal line filtering to maintain signal integrity.
- AEC-Q200 qualified construction ensures robust performance and reliability for automotive electronic environments.
- Compact 0805 surface-mount footprint allows for efficient space utilization on densely populated circuit boards.
Applications
- High-speed differential data transmission interfaces
- Automotive infotainment and connectivity systems
- Multi-gigabit Ethernet connections
Procurement Notes
Verify the specific suffix 'T06' against official TDK documentation to confirm tape and reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for the design.
Selection Notes
Select this component when filtering high-frequency noise on differential pairs without introducing excessive insertion loss. The 90 Ohm impedance provides effective attenuation for common mode signals above 100 MHz. Consider the 300 mA current limit to ensure the component does not saturate during peak operational currents in the signal path.
Part Context
This part belongs to the ACM-H series, which focuses on high-performance filtering for demanding digital interfaces. Unlike standard power line chokes, these components are optimized for preserving the timing and amplitude of high-speed data signals while suppressing radiated emissions.
Replacement Considerations
Direct substitutes include other ACM2012H variants with identical 90 Ohm impedance and 300 mA ratings, such as ACM2012H-900-2P-T05 or ACM2012H-900-2P-T001, provided pin compatibility and packaging requirements align.
