Fixed Inductors Procurement Notes

Verify the specific suffix code when ordering to confirm the required tolerance level, as the series supports multiple options including K for ±10% and M for ±20%. Ensure the selected variant matches the circuit's precision requirements. Confirm that the 0805 package dimensions align with the PCB layout constraints before finalizing the procurement order.

Fixed Inductors Selection Notes

Select this component based on its low inductance value of 2.2 nH and low DC resistance of 80 mOhm, which are critical for minimizing signal loss in high-frequency paths. The ceramic core provides stability against saturation effects compared to iron powder cores. Consider the operating temperature range of -40°C to 125°C to ensure reliability under varying environmental conditions.

Fixed Inductors Part Context

This part belongs to the CT0805CSF series, which covers a wide range of inductances from 2.2 nH to 2700 nH. The series is characterized by wirewound technology and ceramic cores, offering consistent performance across various general-purpose electronic applications. It serves as a fundamental passive component for signal integrity and power line filtering in modern electronics.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 2.2 nH inductance, 0805 package, and ceramic core construction. Verify that any alternative component maintains similar DC resistance and tolerance levels to ensure circuit compatibility without redesign.
