Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Signal Transformer documentation to confirm authenticity. Ensure the specific package dimensions and electrical ratings match the design requirements. Check for RoHS compliance status if environmental regulations apply. Confirm availability through authorized distributors as lead times may vary. Validate that the component meets all necessary safety and performance standards for the intended application environment.

Fixed Inductors Selection Notes

Select this component based on the required 220 uH inductance and 800 mA current handling capability. Consider the 747 mohms DC resistance impact on efficiency. Evaluate the surface-mount form factor for space constraints. Compare with alternative models like SC104B-221 or SC3DF-221 if different current or resistance specifications are needed. Ensure compatibility with the operating frequency of 100KHz.

Fixed Inductors Part Context

This component is part of the Signal Transformer fixed inductor lineup, specifically designed for power applications. It falls under the broader category of SMD power inductors used in electronic systems requiring magnetic energy storage. The product line supports various inductance values and current ratings to meet diverse design needs.

Fixed Inductors Replacement Considerations

The SC104B-221 offers similar inductance but differs in current rating (0.53A) and resistance (721 mohms). The SC3DF-221 provides the same inductance but has lower current handling (0.13A) and higher resistance (6.65 ohms). Verify electrical compatibility before substitution.
