0805J0500681MCTE01

Overview

The Knowles Syfer 0805J0500681MCTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 680 pF with a DC voltage rating of 50 VDC. The component utilizes a C0G (NP0) dielectric material to ensure stable performance across varying conditions. It is housed in an 0805 (2012 metric) package with SMD/SMT termination. The device supports a current rating of 300 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated three-terminal feed-through architecture for enhanced EMI filtering
• High-frequency noise suppression capabilities via internal ground plane structure
• Stable capacitance characteristics maintained through C0G/NP0 dielectric technology

Applications

• RF circuit noise filtering
• Power supply line decoupling
• High-speed digital signal integrity protection

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with existing PCB footprint designs, as feed-through capacitors require distinct pad layouts compared to standard MLCCs. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when compact EMI filtering is required in space-constrained designs. The 0805 form factor allows for dense board placement while maintaining effective high-frequency attenuation. Consider the 300 mA current rating to ensure adequate handling for the target application's power lines without thermal degradation.

Part Context
