0805J1000390MCTE07

Overview

The Knowles Syfer 0805J1000390MCTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 39 pF with a voltage rating of 100 VDC and a current handling capacity of 1 A. The component utilizes a C0G (NP0) dielectric to ensure stable performance across varying conditions. It is housed in an 0805 (2012 metric) package, providing a compact footprint suitable for dense circuit layouts.

Feature Summary

• Integrated feed-through architecture for effective electromagnetic interference filtering
• High current handling capability of 1 A for robust power line protection
• Stable C0G/NP0 dielectric material ensuring minimal capacitance variation

Applications

• RF signal path noise suppression
• Power supply line filtering
• High-frequency circuit decoupling

Procurement Notes

Verify the specific suffix E07 against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with PCB pad designs intended for feed-through components. Cross-reference manufacturer part numbers to avoid confusion with standard MLCC variants that lack the internal conductive structure.

Selection Notes

Select this component when integrated filtering is required within a limited space. The 0805 form factor allows for direct placement on standard SMD pads. Consider the 1 A current rating to ensure the component can handle the expected load without degradation. Verify impedance characteristics at the target operating frequency against circuit requirements.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. These components integrate the capacitor element with a central conductor, functioning as both a filter and a connection point. They are engineered for applications requiring superior high-frequency attenuation compared to discrete components.

Replacement Considerations

Direct substitutes must match the 39 pF capacitance, 100 V rating, and 1 A current capacity. Verify that alternative parts support the feed-through topology rather than standard two-terminal configurations. Check for identical 0805 dimensional constraints to ensure mechanical fit.
