Procurement Notes
Verify the specific part number suffix against official Central Technologies documentation to confirm compliance status and tolerance codes. Ensure that the ordering specifications match the required inductance and DC resistance values. Confirm that the component meets the necessary environmental standards for the intended application before procurement.
Selection Notes
Select this component based on its 20 nH inductance value and low DC resistance profile suitable for high-frequency applications. Consider the 0402 footprint constraints and the operating temperature range up to 155 °C. Evaluate the multilayer technology requirements against alternative wire-wound options if higher current handling is needed.
Part Context
This component belongs to the CT0402CSF series of fixed inductors from Central Technologies. The series includes various inductance values and tolerance codes. The CT0402CSF designation indicates a multilayer construction, distinguishing it from the wire-wound CT0402CS variants which may have different electrical characteristics and packaging details.
Replacement Considerations
Check for other values within the CT0402CSF series such as CT0402CSF-11NG or CT0402CSF-51NG if different inductance is required. Verify compatibility with existing circuit designs when substituting components.
