SC-08-440

Common Mode Chokes Overview

The KEMET SC-08-440 is a through-hole common mode choke belonging to the SC series. It features a 4.4 mH inductance and supports a current rating of 8 A with a DC resistance of 0.025 Ohms. Rated for 250 V, this component utilizes proprietary 5H, 7H, or 10H ferrite materials suitable for frequencies greater than or equal to 150 kHz. The device is housed in a toroidal package designed for robust electromagnetic interference suppression.

Common Mode Chokes Feature Summary

• Utilizes proprietary 5H, 7H, and 10H ferrite core materials for effective noise filtering
• Toroidal construction provides high efficiency in common mode interference suppression
• Designed for operation in frequency ranges starting from 150 kHz

Common Mode Chokes Applications

• AC line filter circuits
• Electromagnetic interference (EMI) suppression
• Power supply input stages

Common Mode Chokes Procurement Notes

Verify the specific ferrite material grade (5H, 7H, or 10H) required for your application, as these variants may have distinct performance characteristics despite sharing the base model number. Confirm that the 8 A current rating and 0.025 Ohm DC resistance align with your circuit's thermal and electrical requirements before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing filters for frequencies at or above 150 kHz requiring high current handling capabilities. Ensure the through-hole mounting style fits your PCB layout constraints. Compare the 4.4 mH inductance against your target attenuation specifications to verify adequate noise reduction for the intended power line environment.

Common Mode Chokes Part Context

The SC series represents KEMET's line of toroidal common mode chokes engineered for general-purpose EMI filtering. These components are characterized by their use of specialized ferrite materials to achieve stable inductance across varying conditions. The SC-08-440 specifically addresses applications needing moderate inductance with significant current capacity.

Common Mode Chokes Replacement Considerations

Check datasheets for other SC series parts or equivalent toroidal chokes from different manufacturers. Ensure replacement units match the 4.4 mH inductance, 8 A current rating, and 250 V voltage rating while maintaining compatible physical dimensions for through-hole installation.
