Overview
The ACM2012-402-2P-T002 is a surface-mount common mode filter from the TDK ACM series, designed for signal lines. It features two channels with an impedance of 4 kOhms at 100 MHz and a maximum DC current rating of 150 mA. The component has a maximum DC resistance (DCR) of 900 mOhms and operates within a temperature range of -40°C to +85°C. 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 style.
Feature Summary
- Provides high common mode noise suppression for differential signal lines through elevated impedance characteristics.
- Maintains low differential mode impedance to minimize impact on high-speed signal integrity.
- Achieves significant size reduction compared to traditional wound-type common mode filters.
Applications
- Noise suppression for high-speed differential signal lines
- Computer peripheral USB connections
- IEEE1394 and Ethernet interfaces
- LVDS and Panel Link connections for LCD screens
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration, as variations exist within the ACM family. Confirm that the 150 mA rating meets the circuit's operational requirements. Ensure the 0805 footprint matches the PCB layout. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when high attenuation is required for high-frequency noise on compact signal traces. The 4 kOhm impedance suits applications needing strong filtering where lower current capacity is acceptable. Compare with lower impedance variants if signal speed or current demands exceed 150 mA. Ensure the operating temperature range covers the environmental conditions.
Part Context
This part belongs to the TDK ACM series of chip common mode filters. These components are engineered to suppress electromagnetic interference in digital circuits. The ACM series offers various impedance and current ratings across different package sizes to accommodate diverse signal line requirements in consumer electronics and computing devices.
Replacement Considerations
ACM2012-402-2P-T001 is a documented alternative within the same series. Verify pin compatibility and electrical parameters before substitution. Other ACM2012 variants may differ significantly in impedance or current handling capabilities.
