The CL21A226MPQNNNE from Samsung Electro-Mechanics is a general-purpose multilayer ceramic capacitor with a nominal capacitance of 22μF, a capacitance tolerance of ±20%, a rated voltage of 10V DC, and an X5R dielectric. It is suitable for power-supply decoupling, bypassing, filtering, energy storage, and voltage-smoothing applications.
The component is supplied in a compact 0805-inch／2012-metric surface-mount package. Its specified dimensions are 2.00±0.15mm in length, 1.25±0.15mm in width, and 1.25±0.15mm in thickness, making it suitable for high-density and space-constrained PCB designs.
The X5R dielectric supports an operating-temperature range from -55°C to +85°C. As a high-capacitance Class II ceramic capacitor, its effective capacitance can vary with DC bias, temperature, frequency, and applied AC voltage. These conditions should be evaluated in the final circuit design.
The final “E” packaging code specifies a 7-inch embossed tape-and-reel option for automated SMT assembly. Samsung lists the part as being in mass production and compliant with RoHS and REACH requirements.
