FAQ

What is the primary structural difference between this component and a standard MLCC?

This component is a feed-through capacitor, meaning the signal passes through the center conductor rather than across the top and bottom electrodes like a standard MLCC, providing integrated filtering.

How does the termination type affect mechanical reliability?

The flexible soft termination absorbs mechanical strain from board flexing, significantly reducing the risk of internal electrode cracking compared to standard rigid terminations.
