Common Mode Chokes Feature Summary

• Provides common mode noise suppression for single-phase AC power lines
• Utilizes nickel-zinc ferrite core material for effective high-frequency attenuation
• Designed for reliable through-hole PCB mounting with robust mechanical stability

Common Mode Chokes Applications

• AC power input filtering for consumer electronics
• EMI suppression in household appliance power supplies
• Noise reduction in industrial control system power interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix 'GJ' against official KEMET documentation to confirm tolerance and termination specifications. Ensure the ordering part number matches the required inductance value of 2 mH and current rating of 2 A. Cross-reference datasheet revision dates to guarantee compliance with current environmental standards and material declarations before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring 2 mH common mode inductance at 2 A continuous current. The 80 mOhms DCR minimizes power loss compared to higher resistance alternatives. Verify that the 20 mm height fits within the enclosure constraints. Confirm compatibility with standard through-hole assembly processes and soldering temperatures up to 120°C operating limits.

Common Mode Chokes Part Context

This component belongs to the KEMET SC-GJ series of common mode chokes. These devices are engineered for general-purpose EMI filtering in AC mains applications. The series offers various inductance values tailored for different noise profiles while maintaining consistent physical footprints for design flexibility across multiple product generations.

Common Mode Chokes Replacement Considerations

Direct substitutes include KEMET SC-02-20JKH (3 mH) or SC-02-300J (30 mH) if inductance adjustments are permissible. Verify pinout compatibility and thermal characteristics when replacing with components from other manufacturers such as TDK or Murata.
