• Open design suitable for general-purpose filtering
• Surface-mount package configuration

Fixed Inductors Applications

• RF signal processing circuits
• General-purpose filtering applications
• DC-DC converter input or output stages

Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and thermal ratings. Ensure the ordering suffix matches the required inductance value and packaging quantity. Cross-reference the manufacturer's official documentation to validate RoHS compliance status and lead times before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 220 nH is required for high-frequency applications. The 550 MHz self-resonant frequency supports RF usage. Consider the 250 mΩ DC resistance for current handling requirements. Verify that the surface-mount footprint aligns with the PCB layout constraints.

Fixed Inductors Part Context

This part belongs to the CT0805FSF series of fixed wire-wound inductors from Central Technologies. The series offers various inductance values in a standard 0805 surface-mount package. These components are designed for use in consumer electronics and industrial equipment requiring compact passive filtering solutions.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 220 nH inductance, 0805 footprint, and similar SRF characteristics. Check for equivalent DCR limits and current ratings. Verify that alternative manufacturers offer compatible RoHS compliance and tape-and-reel packaging options.
