• Supports high current applications with a 25 A continuous rating and minimal resistive voltage drop.
• Designed for reliable surface integration using standard radial PCB mounting techniques.

Common Mode Chokes Applications

• Electromagnetic interference filtering in industrial three-phase motor drives
• Power supply input stages for heavy machinery control systems
• Noise reduction in renewable energy inverters and converters

Common Mode Chokes Procurement Notes

Verify the specific part number DKIH-3352-254K-NK against official SCHURTER documentation to confirm current availability status. Ensure that the required electrical parameters, including 2.2 mH inductance and 25 A current rating, match the design specifications. Check for RoHS compliance certificates if environmental regulations apply to the final assembly. Confirm package dimensions and pin spacing for PCB layout compatibility before ordering.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust noise attenuation for three-phase AC or DC power lines. The 2.2 mH inductance offers significant impedance at switching frequencies while maintaining low series resistance to minimize power loss. Consider the 25 A current capacity for loads exceeding typical consumer electronics requirements. The radial leaded format simplifies automated placement compared to shielded alternatives, provided magnetic coupling constraints are managed.

Common Mode Chokes Part Context

This component belongs to the DKIH series of common mode chokes from SCHURTER. The series is characterized by high current handling capabilities and compact footprints suitable for dense PCB layouts. These chokes are engineered for industrial environments where reliability under thermal stress is critical. The DKIH-3352 variant specifically addresses three-phase applications, distinguishing it from single-phase counterparts in the same family.

Common Mode Chokes Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Evaluate other DKIH series variants only if electrical parameters such as inductance and current ratings can be adjusted to meet system requirements without compromising performance.
