Additional Details

X7R dielectric capacitors offer a good balance of capacitance stability and temperature performance. They are suitable for applications where capacitance variation with temperature is not critical. The 2220 case size refers to the physical dimensions of the capacitor (5.7mm x 5.0mm). Always refer to the manufacturer's datasheet for detailed specifications, including ESR (Equivalent Series Resistance), ESL (Equivalent Series Inductance), and ripple current ratings. The CKG series is designed for general-purpose applications. The MT in the part number usually refers to tape and reel packaging.
