ACM2520-102-2P-T002

Overview

The ACM2520-102-2P-T002 is a two-channel surface-mount common mode choke from the TDK ACM series. It features an impedance of 1 kOhms at 100 MHz and a maximum DC resistance of 900 mOhms per line. The component supports a rated current of 200 mA with a DC voltage rating of 20 V. Its physical dimensions are 2.5 mm in length, 2.0 mm in width, and 1.3 mm in height. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Designed for high-speed differential signal lines and general signal filtering applications
• Maintains common-mode filter characteristics despite miniaturized wire-wound construction
• Compatible with standard reflow soldering processes for automated assembly

Applications

• High-speed differential signal line protection
• General signal line noise suppression
• Portable electronic devices requiring compact filtering solutions

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as packaging variations may exist. Confirm that the target application environment remains within the specified operating temperature limits. Ensure compatibility with the intended PCB footprint and soldering profile during integration planning.

Selection Notes

Select this component for circuits requiring low-profile common mode filtering on high-speed interfaces. Evaluate the 200 mA current rating against peak load requirements to prevent saturation. Consider the 1 kOhm impedance specification relative to the target noise frequencies for effective attenuation performance.

Part Context

This part belongs to the ACM series of chip-type filters manufactured by TDK. The series utilizes wire-wound technology to achieve significant size reduction while preserving necessary filtering characteristics. The ACM2520 package represents a specific form factor within this broader product family.

Replacement Considerations

ACM2520-102-2P is listed as obsolete. ACM2520-102-2P-T002 is documented as a similar substitute.
