- EMI suppression in electronic equipment
Procurement Notes
Verify the specific voltage rating and current capacity requirements against the application design specifications before procurement. Confirm that the through-hole mounting style aligns with the PCB layout constraints. Ensure compatibility with the intended operating temperature range and environmental conditions for reliable long-term performance in the target system.
Selection Notes
Select this component when common mode noise attenuation is required on AC lines with currents up to 4 A. Consider the low DC resistance to minimize power loss and heat generation. Evaluate the physical dimensions and lead configuration to ensure proper fit within the enclosure and assembly process compared to alternative surface mount or different through-hole options.
Part Context
This part belongs to KEMET's SU-16VD series of common mode chokes. These components are engineered for robust performance in power filtering scenarios. The series offers various inductance and current ratings to suit different power line requirements, providing a standardized solution for EMI reduction in commercial and industrial electronics.
Replacement Considerations
Check for compatible common mode chokes with similar inductance (20 µH) and current rating (4 A). Verify that substitute parts maintain the same through-hole package type and voltage rating to ensure mechanical and electrical compatibility without redesigning the circuit board.
