Procurement Notes
Verify the specific part number SSHB21HS-05440 against official KEMET documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with required voltage ratings and current loads for the target application. Check for RoHS compliance status if environmental regulations apply. Confirm lead availability and manufacturing origin through authorized distributors.
Selection Notes
Select this component when dual-line common mode filtering is required with moderate inductance values. Consider the 500 mA current rating and 1.88 Ω resistance for power loss calculations. Evaluate the through-hole package suitability for the PCB layout. Verify that the 250 V ac rating meets the system's insulation requirements.
Part Context
This component belongs to KEMET's SSHB21HS series of wide-range impedance common mode chokes. The series offers various inductance options tailored for different noise suppression needs. These components are typically used in applications requiring robust EMI performance in compact through-hole designs.
Replacement Considerations
Consult KEMET datasheets for direct substitutes within the SSHB21HS series or equivalent models from other manufacturers. Ensure replacement parts match the 44 mH inductance, 500 mA current rating, and 1.88 Ω resistance specifications. Verify physical footprint compatibility for through-hole mounting.
