CL21B334KAFNNNE – SAMSUNG

Overview

The SAMSUNG CL21B334KAFNNNE is a high-performance ceramic capacitor designed for general-purpose applications, offering a stable 0.33 µF capacitance at a 25V rating. Its X7R dielectric ensures predictable performance across a wide temperature range (-55°C to 125°C), making it suitable for demanding environments. A critical design consideration for X7R dielectrics is their inherent capacitance drift with applied DC bias; designers must account for this reduction in effective capacitance when selecting this component for filtering or decoupling circuits where precise impedance matching is paramount.
