CL21B105KOFNNNE – SAMSUNG

Overview

The SAMSUNG CL21B105KOFNNNE is a 1 µF, 16V X7R dielectric ceramic capacitor designed for surface-mount applications. Its primary function is energy storage and filtering, critical for maintaining stable voltage rails in sensitive electronic circuits. While the X7R dielectric offers a good balance between capacitance density and temperature stability compared to Class 2 dielectrics like Y5V, designers must account for its inherent capacitance drift with applied DC bias, which can significantly reduce effective capacitance in high-voltage or high-impedance designs.
