This 0402B224K100CT Multilayer Ceramic Capacitors MLCC - SMD/SMT 0.22 uF 10% 10V manufactured by Walsin is a surface mount capacitor designed for low voltage electronics such as cellphones, PDAs, and laptops. It measures 0402B, which is 0.04 inches long by 0.02 inches wide, making it very small and ideal for miniaturized electronics. This product has a rated capacitance of 0.22 uF (microfarads), a voltage rating of 10V, and a tolerance of 10%, meaning that it can hold a capacitance that is within 10% of the rated value. Its temperature characteristics and dielectric is NPO/COG, which is a non-polarized and temperature resistant material, allowing it to perform in a wide variety of application environments. The body has a C0G/NP0 dielectric, making it very reliable in cold and temperature-sensitive environments. It is perfect for designing small products where space is at a premium, and its low ESR makes it suitable for high frequency applications.
