0805J1000390MCTE01

Overview

The Knowles Syfer 0805J1000390MCTE01 is a surface-mount feedthrough capacitor with a capacitance of 39 pF and a DC voltage rating of 100 VDC. It utilizes C0G (NP0) dielectric material, ensuring stable performance across varying temperatures. The component features a ±20% tolerance and is housed in an 0805 (2012 metric) package. Designed for high-frequency applications, it offers low parasitic inductance through its internal feedthrough structure, making it suitable for EMI suppression in compact electronic designs.

Feature Summary

• Integrated feedthrough architecture provides superior high-frequency noise attenuation compared to standard MLCCs
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes
• Compact 0805 footprint allows for dense PCB layout while maintaining effective electromagnetic interference filtering

Applications

• High-frequency signal line filtering in communication equipment
• EMI suppression in sensitive analog circuits
• Power supply input filtering for RF modules

Procurement Notes

Verify the specific suffix 'TE01' against official manufacturer documentation to confirm packaging details and exact electrical tolerances. Ensure compatibility with automated pick-and-place processes given the small 0805 form factor. Cross-reference with distributor datasheets to confirm RoHS compliance status and moisture sensitivity level prior to procurement.

Selection Notes

Select this component when space constraints require a 0805 footprint but superior high-frequency filtering performance is needed. The C0G dielectric makes it ideal for applications requiring stable capacitance under bias and temperature variations. Consider the feedthrough design for improved impedance characteristics at GHz frequencies compared to conventional parallel-plate capacitors.

Part Context

This part belongs to the Knowles Syfer Syfer® family of high-reliability ceramic components. The '0805J' prefix indicates the case size and general product line, while the numerical sequence defines the specific capacitance and voltage ratings. Feedthrough capacitors in this series are engineered for demanding environments where traditional capacitors may fail due to parasitic effects.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model variant are not available in the provided source data. Verify if generic 0805 39pF 100V C0G feedthrough capacitors from other manufacturers meet the specific inductance and current requirements before substitution.
