Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the tolerance code matches project requirements. Ensure the component selection aligns with the required operating temperature range and current ratings. Confirm RoHS compliance status prior to procurement as lead-free variants may differ from standard specifications.

Fixed Inductors Selection Notes

Select this component when a compact 0402 footprint is required for low-inductance RF applications. Consider the 0.14 Ω DC resistance for power loss calculations. Evaluate the 4400 MHz self-resonant frequency against the target signal bandwidth to ensure effective operation without parasitic resonance issues.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series offers a wide range of inductance values from 1.0 nH to 68 nH in the same 0402 package. Variants are available with different tolerance codes to suit precision or general-purpose circuit needs.

Fixed Inductors Replacement Considerations

Compatible substitutes include other 0402 ceramic-core wire-wound inductors with 82 nH nominal inductance and ±5% tolerance. Verify that replacement parts match the 0.14 Ω maximum DC resistance and 0.68 A current rating to maintain circuit performance.
