• Utilizes ferrite core material for effective filtering
• Designed for PCB mount installation via through-hole termination

Common Mode Chokes Applications

• AC line filtering in electronic equipment
• Noise suppression in power supply circuits
• EMI reduction in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as some sources indicate varying DC resistance values (e.g., 110 mOhms vs. 30 mOhms) or current ratings. Ensure the package type matches the target PCB footprint and that the operating temperature range meets system requirements. Confirm RoHS compliance status directly from the manufacturer's documentation.

Common Mode Chokes Selection Notes

Select this component when a 3 mH inductance at 2 A is required for common mode noise attenuation. Consider the physical dimensions and lead spacing for board layout compatibility. Evaluate thermal performance under load to ensure operation remains within the specified -40°C to +120°C range without exceeding saturation limits.

Common Mode Chokes Part Context

This part belongs to the KEMET SC-J series of common mode chokes. The series offers various inductance values tailored for AC line filtering applications. The SC-02-30J specifically targets low-inductance requirements compared to higher-value counterparts in the same family, balancing size and performance for compact designs.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the SC-J series with matching inductance and current ratings. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers to ensure mechanical fit and electrical equivalence.
