Overview
The ACM4520V-421-2P-TL00 is a two-channel common mode choke from the TDK ACM-V series, designed for surface mount PCB integration. It features an unshielded wire-wound structure with a ferrite core, measuring 4.7mm x 4.5mm x 2mm. The component provides 600 nH inductance and 230 Ohms impedance at 100 MHz. It supports a maximum DC current of 1.5 A with a maximum DC resistance of 50 mOhms per line. Operating temperatures range from -40°C to +125°C. It holds AEC-Q200 qualification.
Feature Summary
- Provides effective suppression of common mode noise in dual-line power circuits through high impedance characteristics.
- Features an unshielded design suitable for applications where magnetic field interference with adjacent components is not critical.
- Complies with automotive reliability standards via AEC-Q200 qualification for robust performance under varying thermal conditions.
Applications
- Automotive electronic systems requiring AEC-Q200 compliant filtering
- Power line noise suppression in compact PCB layouts
- Dual-channel signal integrity protection in consumer electronics
Procurement Notes
Verify the specific suffix TL00 against official TDK documentation to confirm reel packaging specifications. Confirm end-of-life status as NRND before finalizing designs. Ensure compatibility with existing footprint dimensions of 4.7mm by 4.5mm. Validate thermal ratings against system operating environments. Cross-reference part numbers with authorized distributors to avoid obsolete stock.
Selection Notes
Select this component when dual-channel filtering is required within a 4520V package size. Consider the 1.5A current rating and 50mOhm resistance for power efficiency needs. The unshielded nature requires careful layout planning to minimize EMI coupling. Verify AEC-Q200 compliance if used in automotive contexts. Compare impedance curves against target noise frequencies to ensure adequate attenuation.
Part Context
This part belongs to the ACM-V series of common mode chokes manufactured by TDK Corporation. The series offers various inductance and current ratings in standardized surface mount packages. The ACM4520V variant specifically targets space-constrained applications requiring reliable noise suppression. The V suffix typically denotes specific packaging or tape-and-reel configurations within the product line.
Replacement Considerations
Official recommended substitutes include ACM55V-701-2PL-TL00. Verify dimensional compatibility and electrical parameter equivalence before substitution. Check for updated manufacturing status as the original part is marked NRND. Consult TDK datasheets for direct pin-to-pin alternatives within the ACM family.
