Procurement Notes
Verify the specific manufacturer part number 47718-232 against official Vicor documentation to ensure compatibility with your design requirements. Confirm that the through-hole termination style and physical dimensions align with your PCB layout constraints. Ensure that the 8 A current rating and 2.26 mH inductance meet the electrical specifications of your target application before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring robust common mode noise attenuation for high-current DC lines. The 7 kohm impedance at 1 MHz makes it suitable for suppressing high-frequency interference. Consider the 26.5 mm x 26 mm footprint and through-hole mounting requirement during the mechanical design phase to ensure proper integration into the system architecture.
Part Context
This component belongs to the Vicor common mode chokes category, specifically engineered for power electronics applications. It complements Vicor's DCM series converters by providing necessary EMI filtering. The device is manufactured under Vicor Corporation standards, ensuring quality and reliability for demanding industrial and commercial power supply environments.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific component. Verify compatibility carefully if considering alternatives from other manufacturers, as inductance values, current ratings, and physical dimensions may differ significantly.
