0805CS-331EJFS

Fixed Inductors Overview

The Delta Electronics/Components 0805CS-331EJFS is a fixed surface-mount inductor designed for high-frequency applications. It features a ceramic drum core and wirewound construction within an 0805 (2012 metric) package, measuring 2.29mm x 1.80mm x 1.55mm maximum height. The component provides an inductance of 330 nH with a tolerance of ±5%. It supports a rated current of 650 mA and exhibits a DC resistance of 350 mOhm. Electrical performance includes a Q factor of 60 at 500 MHz and a self-resonant frequency of 2.05 GHz. It operates reliably between -40°C and 125°C.

Fixed Inductors Feature Summary

• Utilizes a ceramic drum core and wirewound architecture for stable inductive properties

• Supports surface mount installation in compact 0805 form factors

Fixed Inductors Applications

• RF signal processing circuits
• High-frequency power supply filtering
• Impedance matching networks

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates ±5% tolerance and 'F' denotes tape and reel packaging when sourcing. Confirm RoHS3 compliance and MSL Level 1 status for assembly compatibility. Ensure the supplier documentation explicitly references the 0805CS series datasheet to validate the 350 mOhm DCR and 650 mA rating against potential variant substitutions.

Fixed Inductors Selection Notes

Select this component when a 330 nH value is required with a 650 mA current handling capacity in a standard 0805 footprint. Consider the 350 mOhm DC resistance for efficiency calculations in low-voltage applications. The 2.05 GHz self-resonant frequency defines the upper operational limit for effective inductive behavior in RF designs.

Fixed Inductors Part Context

This part belongs to the 0805CS series of fixed inductors from Delta Electronics/Components. The series offers various inductance values within the 0805 package size, utilizing ceramic drum cores. This specific model represents a mid-range inductance option optimized for frequencies up to several hundred megahertz, balancing size constraints with current handling capabilities.

Fixed Inductors Replacement Considerations

Direct substitutes include the 0805CS-330EJTS, which shares the same 330 nH inductance but differs in current rating (500 mA) and DC resistance (270 mOhm). Verify that the lower current rating of the alternative does not compromise circuit reliability under peak load conditions.
