CT0603CSF-22NG

Fixed Inductors Overview

The CT0603CSF-22NG is a fixed wire-wound chip inductor from Central Technologies, designed for surface-mount applications. It features a ceramic core and operates within a temperature range of -40 °C to 125 °C. The component has a nominal inductance of 22 nH with a tolerance of ±2%. Key electrical specifications include a maximum DC resistance of 0.135 Ω, a minimum quality factor of 28 at the nominal inductance, and a self-resonant frequency of 3 GHz. The device is RoHS compliant and lead-free.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for high-current general-purpose applications
• Surface-mount 0603 package design for compact circuit integration
• High self-resonant frequency capability up to 3 GHz

Fixed Inductors Applications

• RF circuits requiring specific low-inductance values
• General-purpose filtering in high-frequency signal paths
• Power supply input/output stages for current handling

Fixed Inductors Procurement Notes

Verify the ordering suffix 'G' corresponds to the required ±2% tolerance when placing orders. Confirm that the RoHS compliance status matches project requirements, as some variants in this series may differ. Ensure the 0603 footprint aligns with the PCB layout constraints. Check for any specific storage or handling instructions related to the ceramic core material.

Fixed Inductors Selection Notes

Select this component when a precise 22 nH inductance with tight ±2% tolerance is required. The wire-wound design offers higher distributed capacitance compared to thin-film alternatives, resulting in a 3 GHz self-resonant frequency. Consider the 0.135 Ω DC resistance for power loss calculations and ensure the operating temperature range fits the environmental conditions.

Fixed Inductors Part Context

This part belongs to the CT0603CSF series of wire-wound chip inductors manufactured by Central Technologies. The series spans inductance values from 1.6 nH to 390 nH, utilizing a consistent 0603 surface-mount package. The 'F' designation typically indicates RoHS compliance and lead-free construction, distinguishing it from non-compliant variants in the broader CT0603CS family.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 22 nH value, ±2% tolerance, and 0603 footprint. Verify that alternative components maintain similar DC resistance and self-resonant frequency characteristics to ensure circuit performance stability without modification.
