0805CT-390EGTS

Overview

The Delta Electronics/Components 0805CT-390EGTS is a fixed wirewound inductor featuring an unshielded drum core design. It provides an inductance of 39 nH with a tolerance of ±2%. The component supports a rated current of 600 mA and exhibits a DC resistance of 330 mΩ. Key electrical characteristics include a Q value of 50 at 500 MHz and a self-resonant frequency of 2.2 GHz. It utilizes a ceramic magnetic core and is housed in a standard 0805 (2012 Metric) surface-mount package, measuring 2.29 mm x 1.73 mm x 1.03 mm.

Feature Summary

• Unshielded drum core construction for minimal interference
• High-frequency performance with 2.2 GHz self-resonant frequency
• Ceramic core material for stable inductance
• Surface-mount compatibility in compact 0805 footprint

Applications

• RF signal filtering in portable devices
• Impedance matching networks in IoT modules
• Power supply input/output filtering in cloud computing equipment
• Automotive electronics signal conditioning

Procurement Notes

Verify the manufacturer part number 0805CT-390EGTS against official Delta Electronics/Components documentation to ensure authenticity. Confirm RoHS3 compliance and MSL level 1 status during intake inspection. Check for physical damage to the ceramic core and solder terminations. Ensure storage conditions maintain moisture sensitivity requirements prior to reflow soldering processes.

Selection Notes

Select this component when a low-inductance, high-self-resonant-frequency solution is required for RF applications. The 600 mA current rating suits moderate power levels, while the 330 mΩ DCR minimizes insertion loss. The unshielded design allows for flexible PCB layout but requires consideration of magnetic field interaction with nearby components.

Part Context

This inductor belongs to the 0805CT series from Delta Electronics/Components, designed for surface-mount assembly. It complements other passive components in the Delta portfolio used across automotive, IoT, and cloud computing sectors. The specific model targets high-frequency circuits requiring precise 39 nH values with tight tolerance stability.

Replacement Considerations

The 0805CS-390EGTS is a related variant within the same series, offering similar inductance but with different current and resistance specifications. Verify pinout compatibility and thermal characteristics before substitution. No direct cross-model functional equivalents are confirmed in public documentation.
