CT1008CSF-182G

Fixed Inductors Overview

The CT1008CSF-182G is a fixed surface-mount wire-wound inductor from Central Technologies, designed for general-purpose 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 1.8 µH with a tolerance of ±2%. Key electrical specifications include a maximum DC resistance of 2.6 Ω, a minimum quality factor of 35 at the test frequency, and a self-resolved frequency of 225 MHz. It is RoHS compliant and lead-free.

Fixed Inductors Feature Summary

• Utilizes a ceramic core construction for stable performance
• Designed for RF inductor applications
• Supports high operating temperatures up to 125°C

Fixed Inductors Applications

• RF circuits
• Filter choke applications
• General purpose signal processing

Fixed Inductors Procurement Notes

Verify the specific suffix 'G' indicates ±2% tolerance when ordering, as other codes like 'J' or 'K' denote different tolerances. Confirm RoHS compliance status and lead-free composition requirements against current project standards. Ensure the 1008 package dimensions align with PCB footprint constraints. Cross-reference the 2.6 Ω DCR limit with circuit current ratings to prevent saturation issues.

Fixed Inductors Selection Notes

Select this component for designs requiring precise 1.8 µH inductance with tight ±2% tolerance. The ceramic core offers stability suitable for RF environments. Verify that the 225 MHz self-resonant frequency meets the operational bandwidth needs. Consider the 1008 SMD form factor for space-constrained layouts. Ensure the 125°C thermal rating exceeds the expected ambient operating conditions.

Fixed Inductors Part Context

This part belongs to the CT1008CSF series of SMD wire-wound chip inductors manufactured by Central Technologies. The series covers a wide inductance range from 3.9 nH to 10,000 nH. The CT1008CSF designation specifically denotes ceramic-core variants, distinguishing them from other series like CT1008PS which may have different shielding or temperature characteristics.

Fixed Inductors Replacement Considerations

Compatible substitutes within the same series include CT1008CSF-182J (±5% tolerance) and CT1008CSF-182K (±10% tolerance). These parts share identical physical dimensions and core materials but differ in inductance precision. Verify if the application can accommodate the wider tolerance bands before substituting.
