1008CS-390EKTS

Overview

The 1008CS-390EKTS is a fixed surface-mount inductor from Delta Electronics/Components, designed for high-frequency applications. It features a ceramic drum core and wirewound construction with no shielding. The component offers an inductance of 39 nH with a tolerance of ±10%. It supports a rated current of 1 A and exhibits a DC resistance of 150 mOhm. Key electrical parameters include a Q value of 50 at 500 MHz and a self-resonant frequency of 1.5 GHz. Measured at a test frequency of 50 MHz, it operates within a temperature range of -40°C to 125°C.

Feature Summary

• Utilizes a ceramic drum core and wirewound structure for stable RF performance
• Provides unshielded design suitable for compact high-frequency circuit layouts
• Engineered for operation across a wide industrial temperature range

Applications

• RF matching networks
• High-frequency signal filtering
• Impedance matching circuits

Procurement Notes

Verify the specific suffix EKTS against official Delta Electronics documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level classifications prior to assembly. Confirm that the 150 mOhm DCR and 1 A current rating align with the target circuit requirements to prevent thermal issues or performance degradation during operation.

Selection Notes

Select this component when a 39 nH inductance is required in a 1008 (2520 metric) footprint. Consider the 1.5 GHz self-resonant frequency limit for high-speed signal integrity. Evaluate the 1 A current handling capability against peak load conditions. Compare the unshielded nature against adjacent components to mitigate potential electromagnetic interference in dense PCB layouts.
