Overview
The ACM4532-102-3P-T001 is a surface-mount common mode choke coil designed for signal line noise suppression. It features three lines with an impedance of 1 kOhms at 100 MHz and a maximum DC current rating of 200 mA. The component has a maximum DC resistance of 600 mOhms and operates within a temperature range of -25°C to +85°C. Its compact dimensions are 4.50mm in length and 3.20mm in width, making it suitable for high-speed differential and general signal lines where common-mode EMI reduction is required.
Feature Summary
- Maintains common mode filter characteristics despite miniaturization
- Designed for high-speed differential and general signal lines
- Provides effective common-mode EMI reduction
Applications
- USB line radiation noise suppression
- High-speed differential signal lines
- General signal lines requiring common-mode noise countermeasures
Procurement Notes
Verify the specific suffix T001 against official TDK documentation to confirm packaging and reel specifications. Ensure the application environment stays within the -25°C to +85°C operating range. Confirm that the 200mA current rating and 600mOhm DCR meet circuit requirements. Check for RoHS compliance status in the latest datasheet before finalizing procurement.
Selection Notes
Select this component when space constraints require a small footprint (4.5x3.2mm) for signal integrity protection. It is appropriate for applications needing 1kOhm impedance at 100MHz. Consider the 200mA current limit for power handling. Compare with other ACM4532 variants if different line counts or impedance values are needed.
Part Context
This part belongs to the ACM4532 series of common mode chokes from TDK Corporation. The series includes various configurations for signal and power lines. The 102-3P designation indicates a 1kOhm impedance, three-line configuration, and specific termination style. These components are widely used in consumer electronics and data processing equipment for EMC compliance.
Replacement Considerations
Check TDK's ACM4532 series for alternatives like ACM4532-102-2P for two-line applications. Verify impedance and current ratings match exactly. Cross-reference with other manufacturers' signal line filters only if pinout and electrical specs are identical.
