SU9H-02080

Overview

The KEMET SU9H-02080 is a through-hole common mode choke from the SU-9H series, designed for power line filtering. It features an inductance of 8 mH and a maximum DC resistance of 6 ohms. The component supports a maximum DC current of 200 mA and withstands up to 250 V AC. It operates within a temperature range of -40 °C to 120 °C, utilizing manganese-zinc ferrite core material.

Feature Summary

• Provides common mode noise suppression for power lines
• Utilizes manganese-zinc ferrite core for effective filtering
• Designed for through-hole PCB mounting

Applications

• Power supply input filtering
• EMI suppression in electronic equipment
• Line filter applications

Procurement Notes

Verify the specific operating temperature range against your design requirements, as sources indicate both -40°C to 120°C and -25°C to 80°C. Confirm the package type is through-hole bobbin. Ensure the 200 mA current rating and 6 ohm DC resistance meet circuit constraints before procurement.

Selection Notes

Select this component when high inductance (8 mH) is required for low-frequency noise attenuation in through-hole designs. Consider the 200 mA current limit and 6 ohm resistance impact on voltage drop. Verify thermal management capabilities given the wide operating temperature options cited in documentation.

Part Context

Part of the KEMET SU-9H series of common mode chokes. These components are engineered for general-purpose EMI filtering in power circuits. The series offers various inductance values with through-hole construction for robust mechanical attachment.

Replacement Considerations

Check for direct substitutes within the SU-9H series or other KEMET common mode chokes with matching 8 mH inductance and 200 mA rating. Verify pin compatibility and physical dimensions for board replacement.
