Overview
The TDK ACM2520-451-2P is a surface-mount common mode choke designed for high-speed differential and general signal lines. It features a 1008 (2520 metric) package with dimensions of 2.5 mm x 2.0 mm x 1.2 mm. The component provides an impedance of 450 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 350 mA with a maximum DC resistance of 400 mOhms per channel. Rated voltage is 20 VDC, and it operates within a temperature range of -40°C to +85°C.
Feature Summary
- Designed for radiation noise suppression in electronic devices
- Effective counteraction of common mode noise on high-speed signal lines
- Suitable for both high-speed differential and general signal applications
Applications
- Radiation noise suppression for electronic devices
- Noise filtering for high-speed differential signal lines
- Common mode noise reduction for general signal lines
Procurement Notes
Verify the specific suffix (-T002) against official TDK documentation to confirm packaging details such as reel quantity or tape specifications. Ensure the selected variant matches the required surface mount process, typically reflow soldering, as indicated in technical attributes. Cross-reference the impedance value of 450 Ohms at 100 MHz with circuit requirements to confirm compatibility with target signal frequencies.
Selection Notes
Select this component when space constraints require a compact 1008 footprint for EMI suppression. The 350 mA current rating suits low-power signal lines rather than power delivery paths. Verify that the 450 Ohm impedance aligns with the noise spectrum of the specific high-speed interface being protected. Confirm operating temperature limits meet the environmental conditions of the final assembly.
Part Context
This part belongs to the TDK ACM series of common mode chokes, specifically engineered for surface mount technology. The ACM2520 designation indicates the physical case size in metric units. These components are categorized under inductors, chokes, and coils, serving critical roles in maintaining signal integrity by attenuating unwanted electromagnetic interference in dense PCB layouts.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in the provided source material. Engineers should consult TDK's official cross-reference tools or datasheets for verified alternatives with matching impedance, current ratings, and package dimensions.
