Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• General purpose line filtering

Procurement Notes

Verify the specific suffix R25056 against official KEMET documentation to confirm the exact electrical parameters, particularly the 5.6 mH inductance and 2.5 A current rating. Ensure the package type matches the required through-hole footprint and that the operating temperature range meets the application's environmental constraints before finalizing procurement.

Selection Notes

Select this component when a dual-line choke with 5.6 mH inductance and 2.5 A current handling is required. Consider the 0.1 Ω DC resistance for power loss calculations. Verify compatibility with the target PCB layout and ensure the 250 VAC voltage rating exceeds the system's peak line voltage.

Part Context

This part belongs to the KEMET SSHB21H series of common mode chokes. These components are designed for general EMI filtering applications in power electronics. The series offers various inductance and current ratings to suit different circuit requirements while maintaining a consistent through-hole form factor.

Replacement Considerations

Check for direct substitutes with identical 5.6 mH inductance, 2.5 A rating, and 0.1 Ω DCR. Ensure replacement parts match the physical dimensions and pinout to maintain PCB compatibility without redesign.
