SC-08-30J

Common Mode Chokes Overview

The KEMET SC-08-30J is a through-hole common mode choke from the SC-J series, designed for AC line filtering applications. It features a 3 mH inductance measured at 100 kHz and supports a maximum DC current of 8 A. The component has a maximum DC resistance of 54 mΩ and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes proprietary iron oxide core materials suitable for frequencies ≥150 kHz. Physical dimensions are approximately 34 mm length, 24 mm depth, and 33 mm height.

Common Mode Chokes Feature Summary

• Utilizes proprietary 5H, 7H, and 10H iron oxide core materials for effective noise suppression
• Designed for high-frequency operation in ranges greater than or equal to 150 kHz
• Through-hole mounting style with robust construction for AC line filter circuits

Common Mode Chokes Applications

• AC line input filtering for electronic equipment
• Common mode noise suppression in power supplies
• EMI reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may list DC resistance values such as 30 mΩ or 54 mΩ depending on the revision or testing standard. Confirm that the package type matches the required PCB footprint, as some distributor listings may reference tray packaging which affects handling procedures. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Common Mode Chokes Selection Notes

Select this component when a 3 mH inductance is required for common mode noise attenuation in AC lines carrying up to 8 A. The SC-J series offers various sizes; ensure the physical dimensions fit the available board space. Consider the core material properties for performance above 150 kHz. Verify voltage ratings against the system's peak line voltages to ensure compliance with safety standards.

Common Mode Chokes Part Context

The SC-08-30J belongs to KEMET’s SC-J series of common mode chokes, which are engineered for power line filtering. This series provides multiple inductance values and current ratings across different physical footprints. The SC-08 variant specifically addresses higher current requirements compared to smaller series members, making it suitable for main power inputs in medium-power devices.

Common Mode Chokes Replacement Considerations

Cross-reference with other SC-J series parts like SC-05-30J for lower current needs or SC-08-10J for different inductance values. Verify pin compatibility and mechanical dimensions before substituting. Ensure equivalent core material specifications are maintained for similar high-frequency performance characteristics.
