1008CS-820EGTS

Overview

The 1008CS-820EGTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring an unshielded drum core wirewound design. It offers an inductance of 82 nH with a tolerance of ±2%. The component supports a rated current of 1 A and exhibits a DC resistance of 220 mΩ. It operates within a temperature range of -40°C to 125°C. Key electrical characteristics include a Q value of 60 at 350 MHz and a self-resonant frequency of 2.4 GHz. The package dimensions are 2.92 mm x 2.79 mm with a maximum height of 2.03 mm.

Feature Summary

• Unshielded drum core wirewound construction for high-frequency stability
• High self-resonant frequency capability up to 2.4 GHz
• Robust thermal performance across extended operating temperatures

Applications

• RF circuit filtering and impedance matching
• DC-DC converter input/output chokes
• Signal processing circuits requiring low parasitic effects

Procurement Notes

Verify the manufacturer part number against official Delta Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required tolerance and packaging format. Check RoHS compliance status as per current regulatory requirements. Ensure storage conditions align with moisture sensitivity level specifications before soldering.

Selection Notes

Select this component when an unshielded inductor with high self-resonant frequency is required for RF applications. The 1008 package size accommodates higher current ratings compared to smaller footprints. Consider the 220 mΩ DC resistance impact on power loss in the final circuit design. Verify that the 1 A rated current meets the operational load requirements.

Part Context

This component belongs to the 1008CS series of ceramic RF inductors manufactured by Delta Electronics/Components. The series provides various inductance values optimized for radio frequency applications. The 1008CS-820EGTS specifically targets designs needing precise 82 nH inductance with minimal shielding interference.

Replacement Considerations

Direct substitutes within the same series include other 1008CS variants with compatible inductance and current ratings. Cross-reference with Delta Electronics' official replacement guide for equivalent components. Ensure any alternative maintains the 1008 footprint and 2.4 GHz self-resonant frequency characteristics.
