Procurement Notes
Verify the specific suffix 'NG' against the manufacturer's current ordering guide to confirm tolerance and packaging specifications. Ensure the selected variant matches the required inductance value and physical footprint for the target PCB layout. Cross-reference the datasheet revision date to confirm compliance with current environmental standards.
Selection Notes
Select this component when a precise 18 nH inductance is required in a minimal 0402 footprint. Consider the low DC resistance for efficiency in power-sensitive RF paths. Evaluate the thermal operating range to ensure suitability for the intended environment. Confirm that the multilayer technology aligns with the frequency requirements of the application.
Part Context
This part belongs to the CT0402CSF series of wire-wound chip inductors designed for general-purpose applications. The series offers various inductance values within the standard 0402 case size, catering to diverse RF and signal conditioning needs in consumer electronics and telecommunications hardware.
Replacement Considerations
Direct substitutes include other 0402 package inductors with 18 nH nominal value and similar DC resistance. Verify pin compatibility and inductance tolerance before swapping. Alternative manufacturers may offer equivalent components with different Q-factor characteristics.
