Overview
The TDK ACM4520-142-2P-T000 is a surface-mount common mode filter from the ACM series, designed for power line applications. It features a ferrite core and wire-wound structure within a 4520 package (4.7mm x 4.5mm x 2mm). The component supports a maximum DC current of 1.5A with a maximum DC resistance of 0.08Ω. It operates between -40°C and +85°C and includes shielding.
Feature Summary
- Wire-wound construction using ferrite core material
- Shielded design to minimize electromagnetic interference
- Single choke configuration for common mode noise suppression
Applications
- Power line filtering
- General use electronic circuits
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with your PCB footprint and thermal requirements. Confirm availability status directly with authorized distributors as supply levels fluctuate. Check for any recent product change notifications that may affect specifications or manufacturing location.
Selection Notes
Select this component when a compact, shielded common mode filter is required for power lines. The 4520 package offers a balance of size and performance. Consider the 1.5A current rating and 0.08Ω resistance for circuit efficiency. Verify if the standard temperature range meets your operational environment needs compared to the automotive-grade ACM-V series.
Part Context
This part belongs to the TDK ACM series of surface-mount common mode filters. It shares the physical 4520 footprint with other variants like the ACM4520V series but differs in electrical ratings and qualification standards. The ACM4520 series is distinct from the AEC-Q200 qualified ACM-V series, targeting general industrial and consumer electronics rather than automotive applications.
Replacement Considerations
ACM4520-142-2P-TL000 is an equivalent variant within the same series. Cross-referencing with ACM4520V-142-2P-T00 requires verification of temperature range and qualification differences.
