Overview
The ACM4520-142-2P-TL000 is a surface-mount common mode choke from the TDK ACM-V series, designed for power line applications. It features a wire-wound structure in a 4520 package (4.7 x 4.5 x 2 mm). Key electrical parameters include a rated DC current of 1.5 A and a maximum DC resistance of 0.08 Ω. The impedance is specified as 1.4 kΩ at 100 MHz. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 qualification.
Feature Summary
- Provides common mode noise suppression for power lines
- AEC-Q200 qualified for automotive reliability standards
- Compact surface-mount design suitable for space-constrained PCBs
Applications
- Power line filtering in electronic circuits
- Automotive electronics systems requiring AEC-Q200 components
- General use EMC suppression applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and packaging specifications against the official datasheet. Check for obsolescence status, as availability may be limited. Ensure storage conditions comply with moisture sensitivity levels defined in the product documentation prior to assembly.
Selection Notes
Select this component when a compact, automotive-grade common mode choke is required for power line filtering. The 1.5 A current rating and low DC resistance make it suitable for moderate power applications. Verify that the 4520 footprint matches the PCB layout constraints and that the 1.4 kΩ impedance at 100 MHz meets the specific EMI suppression requirements of the target circuit.
Part Context
This part belongs to the TDK ACM-V series of surface-mount common mode chokes. The series offers various impedance values and current ratings in standardized packages. The ACM4520 variant specifically provides a balance between size and performance, targeting applications where board space is limited but robust noise filtering is necessary for signal integrity and compliance.
Replacement Considerations
Check for equivalent parts such as ACM4520V-142-2P-TL00 if functional compatibility is required. Verify pinout, impedance characteristics, and current ratings before substitution. Ensure any replacement maintains the same package dimensions and thermal performance to fit existing designs without modification.
