About Ceramic Capacitors

Multilayer ceramic capacitors (MLCCs) serve as fundamental building blocks in modern electronics, storing charge and filtering noise in power delivery networks. Their non-polarized design accommodates AC/DC signals while offering superior frequency response compared to electrolytic alternatives.

X7R MLCCs strike an optimal balance between stability and capacitance density, making them ideal for general-purpose applications where moderate temperature fluctuations occur. Surface-mount variants like 0805 packages dominate PCB designs due to their space efficiency and compatibility with high-speed assembly lines.

Packaging Options

Available in industry-standard formats: Tape & Reel (TR) for automated assembly, Cut Tape (CT) for prototyping, and Digi-Reel® for flexible quantity requirements.
