0805CT-820EJTS

Overview

The Delta Electronics/Components 0805CT-820EJTS is a fixed surface-mount inductor with an 82 nH nominal inductance and ±5% tolerance. It features a ceramic drum core wirewound construction, offering a rated current of 500 mA and a DC resistance of 440 mΩ. The component operates within a temperature range of -40°C to 125°C and exhibits a Q value of 50 at 500 MHz. Its self-resonant frequency reaches 1.5 GHz, measured at a test frequency of 150 MHz. Housed in a standard 0805 (2012 Metric) package measuring 2.29mm x 1.73mm x 1.03mm, it provides unshielded performance suitable for high-frequency applications.

Feature Summary

• Utilizes a ceramic drum core wirewound design for stable inductance characteristics
• Provides high self-resonant frequency capability up to 1.5 GHz
• Supports operation across an extended industrial temperature range from -40°C to 125°C

Applications

• RF signal filtering circuits
• High-frequency power supply output stages
• Impedance matching networks in communication devices

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variants exist for tape-and-reel, cut tape, and Digi-Reel formats. Confirm RoHS3 compliance status during procurement to meet environmental regulations. Cross-reference the manufacturer part number with distributor codes to prevent selection errors between similar series components. Ensure storage conditions align with the moisture sensitivity level classification prior to assembly.

Selection Notes

Select this component when a compact 0805 footprint is required for high-frequency signal integrity. The 500 mA current rating suits moderate power applications where space constraints limit larger inductors. Consider the 440 mΩ DC resistance for efficiency calculations in low-voltage circuits. The unshielded design may require layout considerations to minimize electromagnetic interference with adjacent sensitive traces.

Part Context

This part belongs to the 0805CT series of fixed inductors from Delta Electronics/Components. The series offers various inductance values within the 0805 package size, catering to diverse RF and power management needs. The 0805CT-820EJTS specifically targets applications requiring precise 82 nH inductance with reliable thermal performance.

Replacement Considerations

Direct substitutes include other 82 nH, 0805 package inductors with comparable current ratings and DC resistance. Verify pin compatibility and thermal specifications before replacing. Similar series parts like the 0805CT-470EGTS offer different electrical characteristics but share the same physical footprint.
