Procurement Notes

Verify the exact suffix against manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure compatibility with peak reflow profiles defined in the official datasheet. Confirm RoHS compliance status through current regulatory declarations prior to integration into final assemblies.

Selection Notes

Select this component when board space constraints require an 0805 footprint combined with integrated filtering capabilities. The feed-through design reduces external component count compared to discrete RC networks. Validate that the 25V rating exceeds maximum circuit operating voltages including transients.

Part Context

This part belongs to the Knowles Syfer MLCC portfolio, specifically engineered for EMI mitigation. Unlike standard capacitors, it utilizes a specialized internal structure to shunt noise currents to ground while passing desired signals. This distinguishes it from general-purpose multilayer ceramic capacitors in the same series.

FAQ

How does the feed-through structure differ from a standard capacitor?

The feed-through design incorporates internal terminals that allow signal lines to pass directly through the component body, providing superior high-frequency noise attenuation compared to standard two-terminal devices.

What is the significance of the X7R dielectric in this application?

X7R provides a balance of high volumetric efficiency and reasonable temperature stability, maintaining capacitance within specified limits across the industrial temperature range required for most electronic systems.
