Overview
The ACM2012-201-2P-T002 is a surface-mount common mode choke from the TDK ACM series, designed for signal line filtering. It features a dual-line configuration with an impedance of 200 Ohms at 100 MHz and a maximum DC current rating of 350 mA. The component exhibits a maximum DC resistance (DCR) of 250 mOhms and supports a rated voltage of 50 VDC. Its compact footprint measures 2.00 mm in length, 1.20 mm in width, and 1.20 mm in height. The device operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides effective common mode noise suppression for high-speed differential signal lines while maintaining low differential mode impedance to minimize signal distortion.
- Achieves significant size reduction through a wound-type chip construction suitable for space-constrained printed circuit board layouts.
Applications
- USB cables for computers and peripheral devices
- IEEE1394 and Ethernet lines for computers and set-top boxes
- LVDS and Panel Link connections for liquid crystal screens
Procurement Notes
Verify the specific part number ACM2012-201-2P-T002 against official TDK documentation to confirm electrical parameters such as 200 Ohm impedance and 350 mA current rating. Ensure compatibility with surface mount assembly processes and check for RoHS compliance status in the latest datasheet before procurement.
Selection Notes
Select this component when filtering high-speed differential signals like USB or LVDS requires a compact form factor. The 200 Ohm impedance at 100 MHz targets specific noise frequencies, while the 350 mA rating suits low-power signal lines. Verify that the 250 mOhm DCR meets system power loss requirements.
Part Context
This component belongs to the TDK ACM series of signal line common mode chokes. The series utilizes wound-type technology to balance noise suppression performance with miniaturization. The ACM2012 package denotes a 2012 metric footprint, widely used in portable electronics and computer peripherals where board space is limited.
Replacement Considerations
Consult TDK's official cross-reference data for verified substitutes. Ensure any replacement matches the 200 Ohm @ 100 MHz impedance, 350 mA current rating, and 2012 package dimensions to maintain circuit integrity.
