CT0805CSF-272G

Fixed Inductors Overview

The CT0805CSF-272G is a general purpose inductor from Central Technologies, designed for surface mount applications. It features a ceramic core and rectangular construction within an 0805 package. The nominal inductance is 2.7 µH with a ±2% tolerance (code G). Key electrical parameters include a DC resistance of 1.4 Ω, a maximum rated current of 0.1 A, and a minimum quality factor of 30 at the nominal inductance. The component operates between -40 °C and 125 °C, has a self-resonant frequency of 150 MHz, and measures 2.35 mm in length, 1.73 mm in width, and 1.52 mm in height.

Fixed Inductors Feature Summary

• Utilizes a ceramic core for stable inductance characteristics in general purpose applications.
• Designed for surface mount technology (SMT) with a compact rectangular footprint.
• Compliant with RoHS standards and lead-free manufacturing requirements.

Fixed Inductors Applications

• Filter choke circuits
• General purpose signal processing
• High-frequency filtering

Fixed Inductors Procurement Notes

Verify the specific tolerance code 'G' corresponds to ±2% accuracy during ordering. Confirm that the 0.1 A current rating meets the application's peak load requirements. Ensure the 1.4 Ω DC resistance is acceptable for the target circuit design. Check compatibility with standard 0805 reflow soldering profiles. Validate that the 150 MHz self-resonant frequency aligns with the operational bandwidth needs.

Fixed Inductors Selection Notes

Select this component when precise inductance control is required due to its tight ±2% tolerance. Consider the low current rating of 0.1 A for low-power signal paths rather than power handling. The ceramic core offers stability suitable for general purpose filtering where high saturation current is not critical. Evaluate the 1.4 Ω DC resistance impact on voltage drop within the specific circuit topology.

Fixed Inductors Part Context

This part belongs to the CT0805CSF series, which provides a wide range of inductance values from 2.2 nH to higher microhenry levels in the 0805 SMD package. The series is characterized by ceramic core construction and compliance with environmental standards. It serves as a standardized passive component option for prototyping and mass production in electronic assemblies requiring reliable surface-mount inductors.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 2.7 µH nominal value, ±2% tolerance, 0805 package dimensions, and ceramic core type. Verify equivalent DC resistance and current ratings to ensure circuit performance parity. Cross-reference manufacturer datasheets for pin-compatible alternatives with identical self-resonant frequency specifications.
