Overview
The AMFC47-3NZ is a through-hole common mode choke manufactured by Aimtec. It features an inductance of 4.7 mH and supports a maximum current rating of 3 A. The component has a typical DC resistance (DCR) of 30 milliohms. It is designed for line applications with a rated voltage of 2000 VDC. Physical dimensions are 19.00 mm in length and 11.00 mm in width.
Feature Summary
- Provides common mode noise suppression for power lines
- Designed for through-hole PCB mounting
- Supports high voltage isolation requirements
Applications
- EMC filtering in AC-DC power supplies
- Input stages of isolated DC-DC converters
- General purpose line interference suppression
Procurement Notes
Verify the specific part number against official Aimtec documentation to ensure compatibility with your circuit design. Confirm that the 3A current rating and 4.7mH inductance meet your system's EMC requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure physical footprint dimensions fit your PCB layout constraints before ordering.
Selection Notes
Select this component when designing power supplies requiring robust common mode noise attenuation. The 4.7 mH value offers significant impedance at switching frequencies. Consider the 3A current capacity for moderate power applications. The through-hole package provides mechanical stability for high-voltage environments where surface mount options may be less suitable.
Part Context
This component belongs to Aimtec's Comet series of EMC filters. Aimtec specializes in modular AC-DC and DC-DC power conversion solutions. The AMFC series is designed to integrate seamlessly with their power supply modules, providing necessary input filtering to meet regulatory emissions standards.
Replacement Considerations
Cross-reference with similar common mode chokes offering 4.7 mH inductance and 3A current ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent voltage ratings and DCR specifications to maintain circuit performance.
