Fixed Inductors Procurement Notes

Verify the specific tolerance suffix when ordering, as the base part number requires a designated letter code to define the exact inductance variance. Confirm RoHS compliance status and lead-free terminal availability through official manufacturer documentation prior to procurement. Ensure the selected variant matches the required operating temperature range and current rating for the target application environment.

Fixed Inductors Selection Notes

Select this component for applications requiring precise low-nanohenry inductance values in compact form factors. Consider the 0.38 A current limit and 6000 MHz resonance characteristics when designing RF or high-speed signal paths. Evaluate thermal requirements against the 85 °C maximum operating temperature specification to ensure long-term reliability in the intended electronic assembly.

Fixed Inductors Part Context

This component belongs to the CTTF0402F series of wire-wound chip inductors from Central Technologies. The series offers a wide range of inductance values from 0.2 nH to 33 nH in the 0402 package. It is designed for general-purpose use in modern electronics where small size and high-frequency stability are critical requirements for circuit performance.

Fixed Inductors Replacement Considerations

Compatible substitutes within the same series include CTTF0402F-3N6 and CTTF0402F-3N1, provided the slight inductance variation aligns with design tolerances. Verify that alternative parts maintain identical package dimensions, current ratings, and self-resonant frequency limits to ensure functional equivalence.
