Procurement Notes
Verify the specific part number against manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing board layouts and thermal management requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement decisions.
Selection Notes
Select this component when high inductance values are required for effective noise attenuation in AC line applications. The dual-mode characteristic allows for comprehensive EMI suppression without additional components. Consider the through-hole form factor for mechanical strength and verify that the 1.8 A current rating meets the circuit's operational demands.
Part Context
This component belongs to the SSHB21HS series of dual-mode chokes from KEMET. These devices are engineered for industrial and commercial applications requiring reliable EMI filtering. The series offers various inductance options tailored to different noise profiles while maintaining consistent physical dimensions for design flexibility.
Replacement Considerations
Potential substitutes include other KEMET dual-mode chokes such as the SSHB21HS-25021 or similar models from the same family. Verify that alternative parts match the 4.6 mH inductance, 1.8 A current rating, and 250 VAC voltage specifications to ensure functional equivalence.
