Fixed Inductors Procurement Notes

Verify the specific tolerance suffix when ordering, as the base part number may require additional coding for precise tolerance selection. Confirm that the package dimensions align with the target PCB footprint. Ensure compliance with RoHS standards if required by the end product regulations. Cross-reference the datasheet for thermal performance limits during high-current operation.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values in a small 0603 footprint. Consider the 440 mA current rating and 0.21 Ω DC resistance for power loss calculations. The 3 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior. Evaluate the Q factor of 40 for resonance requirements in tuned circuits.

Fixed Inductors Part Context

This component belongs to the CT0603QWF series of wire-wound chip inductors from Central Technologies. The series offers various inductance values ranging from 1.6 nH to higher capacities, all housed in a standardized 0603 surface-mount package. These inductors are engineered for general-purpose use in modern electronic assemblies where space constraints and high-frequency performance are critical.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include other CT0603QWF variants with matching inductance and tolerance codes. Verify equivalent parameters such as DCR, current rating, and SRF before substitution. Generic replacements must match the 0603 package dimensions and ceramic core construction to ensure mechanical and electrical compatibility.
