0805CT-820EGTS

Overview

The Delta Electronics/Components 0805CT-820EGTS is a fixed surface-mount inductor with an 82 nH nominal inductance and ±2% tolerance. It utilizes an unshielded drum core wirewound construction on a ceramic substrate, housed in a compact 0805 (2012 Metric) package measuring 2.29mm x 1.73mm x 1.03mm. The component supports a rated current of 500 mA and exhibits a DC resistance of 440 mOhm. Electrical performance includes a Q value of 50 at 500 MHz and a self-resonant frequency of 1.5 GHz, tested at 150 MHz. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Unshielded drum core wirewound design for high-frequency signal integrity
• Compact 0805 footprint suitable for dense PCB layouts
• Ceramic core material providing thermal stability

Applications

• RF circuit filtering
• High-speed digital line termination
• DC-DC converter output chokes

Procurement Notes

Verify the obsolete status before procurement as DigiKey has ceased stocking this item. Confirm that the 0805CT series designation matches the required drum core specifications rather than the CS variant. Ensure the 440 mOhm DCR meets the target power loss constraints. Validate RoHS3 compliance requirements against current environmental regulations.

Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference with nearby traces. The 500 mA rating must align with the maximum expected load current. Consider the 1.5 GHz self-resonant frequency limit for RF applications. The 0805 size offers a balance between current handling and board space efficiency compared to smaller packages.

Part Context

This part belongs to the 0805CT series of fixed inductors from Delta Electronics/Components. It shares the standard 0805 mechanical dimensions but differs from the 0805CS series, which typically features different current ratings and DC resistance values. The CT suffix indicates specific winding and core characteristics distinct from other series variants.

Replacement Considerations

The 0805CS-820EGTS is a related model but has a 400 mA rating and 420 mOhm DCR, requiring verification of current capacity. No direct public substitute part numbers are confirmed in the provided documentation.
