Procurement Notes

Verify the specific ordering suffix to ensure the correct tolerance and packaging configuration matches the design requirements. Confirm that the manufacturer's datasheet specifications align with the intended operating temperature range and current limits before finalizing the procurement order.

Selection Notes

Select this component when a precise, low-inductance value is required for RF or high-speed applications. The unshielded nature requires careful layout consideration to prevent electromagnetic interference coupling with adjacent traces. Ensure the PCB pad design accommodates the 0402 footprint dimensions accurately.

Part Context

This part belongs to the CTTF series of thin film chip inductors from Central Technologies. The series offers various inductance values within the 0402 package, catering to different frequency and current requirements while maintaining consistent manufacturing quality and dimensional standards across the product line.

Replacement Considerations

Direct substitutes include other 2.2 nH unshielded thin film inductors in the 0402 package from manufacturers such as Johanson Technology or TDK, provided they meet the same electrical parameters and thermal characteristics.
