Overview
The T60405-S6122-X018 is a three-phase common mode choke manufactured by Vacuumschmelze. It utilizes Vitroperm nanocrystalline core technology for high-performance filtering. The component features a vertical through-hole mounting style and supports a current rating of 20A. Key electrical parameters include an inductance of 1.67 mH at 100 kHz and a DC resistance of 4.6 mOhm. Impedance is specified as 1.3 kOhms at 100 kHz.
Feature Summary
- Utilizes Vitroperm nanocrystalline material for superior magnetic performance
- Designed for three-phase power line noise suppression
- Vertical through-hole construction for board integration
Applications
- Industrial power supply input filtering
- Three-phase motor drive EMI suppression
- Uninterruptible power system (UPS) noise reduction
Procurement Notes
Verify the specific suffix X018 against official Vacuumschmelze documentation to confirm mechanical dimensions and terminal configuration. Ensure compatibility with existing PCB footprint designs before procurement. Cross-reference impedance and inductance values with the latest datasheet to validate performance requirements for the target application environment.
Selection Notes
Select this component when three-phase noise attenuation is required in compact vertical spaces. The nanocrystalline core offers higher saturation flux density compared to traditional ferrites. Evaluate the 20A current rating against peak load conditions. Consider the 4.6 mOhm DC resistance for thermal management calculations in high-current applications.
Part Context
This part belongs to the T60405 series of common mode chokes from Vacuumschmelze. The series is characterized by the use of Vitroperm alloy cores, which provide low loss and high permeability. These components are engineered for demanding electromagnetic interference suppression tasks in industrial and commercial power electronics systems.
Replacement Considerations
Direct substitutes must match the 20A rating, 1.67 mH inductance, and vertical three-phase form factor. Verify that alternative nanocrystalline chokes maintain similar impedance characteristics at 100 kHz. Mechanical footprint compatibility is critical for direct replacement without PCB redesign.
