Overview
The KEMET SC22-05-30J is a two-line common mode choke designed for through-hole mounting. It features an inductance of 3 mH at 10 kHz and supports a maximum current of 5 A with a DC resistance of 50 mΩ. Rated for 250 V AC, the component operates within a temperature range of -25°C to +120°C.
Feature Summary
- Provides effective common mode noise suppression for two-line circuits
- Utilizes through-hole termination for secure PCB integration
- Engineered for high-current applications up to 5 A
Applications
- Power supply input filtering
- EMI suppression in electronic equipment
- Signal integrity protection in data lines
Procurement Notes
Verify the specific inductance tolerance and current rating requirements against the official datasheet before procurement. Confirm that the through-hole footprint dimensions match the target PCB layout. Ensure the operating temperature range aligns with the environmental conditions of the final assembly to guarantee long-term reliability and performance stability.
Selection Notes
Select this component when a 3 mH inductance value is required for common mode noise reduction in low-voltage AC circuits. The 5 A current rating makes it suitable for moderate power applications. Consider the physical size and through-hole mounting style during the mechanical design phase to ensure adequate clearance and proper soldering access on the printed circuit board.
Part Context
This part belongs to KEMET's SC series of common mode chokes, which are widely used for electromagnetic interference suppression. The SC22-05-30J specifically addresses noise issues in two-wire configurations, offering a balance between inductance performance and current handling capabilities for general industrial and consumer electronics applications.
Replacement Considerations
Consult official KEMET documentation for verified substitute part numbers. Ensure any replacement matches the 3 mH inductance, 5 A current rating, and 250 V AC voltage specifications. Verify compatibility with existing PCB footprints and thermal management requirements.
