2220PC684KAT3A

The 2220PC684KAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established suppliers of passive electronic components. This capacitor is housed in a 2220 surface-mount package, a common form factor that measures approximately 5.6mm x 5.0mm, making it suitable for modern high-density PCB designs while remaining large enough for reliable handling and placement in automated assembly environments. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling across virtually every type of electronic system. The 2220 package size positions this part in the mid-range capacity segment, offering engineers a balance between capacitance value, physical footprint, and voltage rating that works well in space-constrained industrial and consumer applications. AVX's 2220 ceramic capacitors are widely employed in power supply circuits, where they filter voltage ripple and provide localized charge storage near switching regulators and load points. They are also commonly specified in signal conditioning circuits, audio equipment, communications infrastructure, automotive electronics, and industrial control systems. The package size and construction make these capacitors suitable for both single-layer and multilayer PCB designs, including flex circuits in some applications. The "PC" designation in this part number indicates this is a polymer-clay dielectric composition, part of AVX's established ceramic capacitor families. These materials offer engineers a predictable combination of capacitance stability, temperature performance, and voltage handling that has been proven across decades of deployment in field equipment. The specific material system affects the capacitor's behavior under thermal cycling and DC bias conditions—important considerations in industrial environments where temperature swings or high sustained voltages may be present. Engineers typically specify an exact part number like the 2220PC684KAT3A rather than selecting a generic alternative when the specific combination of package size, dielectric material, voltage rating, and capacitance value has been validated for their circuit design. AVX's long-standing presence in industrial supply chains means this component benefits from consistent quality control, established supply reliability, and compatibility with standard pick-and-place equipment used in high-volume manufacturing. Whether you're designing a replacement PCB for existing equipment, upgrading an industrial control system, or developing new hardware, the 2220PC684KAT3A offers a proven solution for general-purpose energy storage and filtering applications where reliable, mid-range ceramic capacitor performance is required.
