Overview
The ACM4520-421-2P-TL000 is a surface-mount common mode choke from the TDK ACM-V series, designed for PCB mounting. It features an AEC-Q200 qualification and operates within a temperature range of -40°C to +125°C. The component has a DC voltage rating of 50V and a maximum DC current of 2.8A. Its impedance is 420 Ohms at 100 MHz, with a maximum DC resistance of 55mOhm. The physical dimensions are 4.7mm x 4.5mm x 2.0mm.
Feature Summary
- Provides common mode noise suppression via a dual-line choke structure.
- Constructed with a shielded wire-wound design using ferrite core material.
- Qualified for automotive applications under the AEC-Q200 standard.
Applications
- General use electronic circuits
- Automotive electronics systems
Procurement Notes
Verify the specific suffix against official documentation, as variations exist between TL00 and T000 endings. Confirm availability status, as some listings indicate non-recommended-for-new-design (NRND) status or limited stock. Ensure the ordering quantity aligns with factory packaging requirements, typically in multiples of 2500 units on reel.
Selection Notes
Select this component when a compact 4520 footprint is required for high-current applications up to 2.8A. The 420 Ohm impedance at 100 MHz targets specific frequency ranges for EMI reduction. Verify that the 50V DC rating meets the circuit's operational voltage requirements and that the 55mOhm DCR fits the power loss constraints.
Part Context
This part belongs to the ACM-V series of common mode chokes manufactured by TDK Corporation. The series offers various impedance values and current ratings within standardized surface-mount packages. The ACM4520 variant specifically provides a balance of size and performance for dense PCB layouts requiring robust noise filtering capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other ACM4520 variants such as ACM4520-901-2P-T000 only if impedance specifications match the design requirements.
