CT1008CSF-221G

Fixed Inductors Overview

The CT1008CSF-221G is a fixed wire-wound 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 220 nH with a tolerance of ±2%. Key electrical parameters include a maximum DC resistance of 0.84 Ω, a minimum quality factor of 25 at the test frequency, and a self-resonant frequency of 950 MHz. The device supports a maximum rated current of 0.65 A and utilizes a dual-ended rectangular package.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for stable RF performance
• Surface-mount chip design compatible with automated assembly
• RoHS compliant manufacturing process

Fixed Inductors Applications

• RF circuit filtering

• Signal processing circuits

Fixed Inductors Procurement Notes

Verify RoHS compliance status as datasheets may vary by production batch. Confirm lead finish specifications against JESD-609 standards. Ensure ordering includes the correct tolerance suffix (G for ±2%) to match circuit requirements. Check for lead-free availability if required by specific environmental regulations.

Fixed Inductors Selection Notes

Select this component for low-inductance RF applications requiring high Q factors. Compare DC resistance and current ratings against load conditions. Consider the self-resonant frequency relative to operating bandwidth. Evaluate thermal limits for high-temperature environments.

Fixed Inductors Part Context

This part belongs to the CT1008CSF series of SMD wire-wound chip inductors. The series offers various inductance values from 3.9 nH to higher ranges, all sharing the 1008 footprint. Variants differ primarily in inductance, tolerance codes, and compliance status.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CT1008CSF-221K or CT1008CSF-221M, which share identical physical dimensions but offer different tolerance levels of ±10% and ±20% respectively.
