08055A220KAT4A

The AVX 08055A220KAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and coupling applications across industrial and consumer electronics. This component belongs to the 0805 metric package family, making it a surface-mount device suitable for automated assembly on printed circuit boards where space is at a premium. Multilayer ceramic capacitors in this size class serve as workhorse components in power distribution networks, signal conditioning circuits, and high-frequency filtering applications. The 0805 package offers a practical balance between board space efficiency and ease of handling during manufacturing. Engineers commonly specify these capacitors in power supply designs, where they function as bulk or local decoupling elements near integrated circuits, helping stabilize voltage rails and suppress transient noise. The "220K" designation indicates the capacitance value in picofarads. This mid-range capacitance makes the part useful in timing circuits, RF filtering, and AC coupling stages where neither extremely small nor very large capacitance values are required. Capacitors in this value range are frequently found in analog signal paths, oscillator circuits, and impedance-matching networks in communication equipment. AVX's MLCC product lines are recognized for consistent performance across temperature ranges typical of industrial environments. The ceramic dielectric material used in these capacitors provides stable capacitance over time and operating conditions, which is critical for applications where circuit performance must remain predictable throughout the product lifecycle. When selecting the 08055A220KAT4A specifically, engineers value several characteristics. The compact 0805 package reduces overall board size and weight compared to larger package alternatives, an important consideration in space-constrained applications. The established presence of this part across multiple suppliers and manufacturing facilities typically means reasonable availability and supply chain stability. The ceramic construction offers inherent durability in harsh industrial environments, resisting vibration, thermal cycling, and humidity better than some alternative dielectric materials. This part is commonly found in telecommunications infrastructure, industrial control systems, automotive electronics, and power management circuits where mid-range filtering and decoupling capacitance is required at standard operating voltages. Engineers might choose this specific component over alternatives when they need a proven, standardized solution that integrates easily into existing manufacturing processes and offers good long-term reliability at competitive cost. The 08055A220KAT4A represents a fundamental building block in modern electronics design, supporting the stable operation of countless industrial and commercial systems.
