1008CS-222EJTS

Overview

The 1008CS-222EJTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a 2.2 µH nominal inductance with ±5% tolerance. It utilizes an unshielded drum core wirewound design on a ceramic substrate, housed in a 1008 (2520 Metric) package measuring 2.92mm x 2.79mm x 2.03mm max. The component supports a rated current of 280 mA and exhibits a DC resistance of 2.8 ohms. Electrical performance includes a self-resonant frequency of 160 MHz and a Q factor of 28 at 50 MHz, tested at 7.9 MHz. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Unshielded drum core wirewound construction for high-frequency signal integrity
• Ceramic core material providing thermal stability across wide operating ranges
• Surface mount packaging optimized for automated assembly processes

Applications

• RF circuit filtering and impedance matching networks

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct tolerance and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference package dimensions with PCB footprint libraries to guarantee mechanical fitment during assembly.

Selection Notes

Select this component when unshielded inductance values are required to minimize magnetic interference with adjacent sensitive circuits. Evaluate the 280 mA current rating against peak load conditions to prevent saturation. Consider the 2.8 ohm DC resistance impact on overall power efficiency and voltage drop characteristics within the target application circuit.
