2225HA221KAT1A

The 2225HA221KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the High Voltage series, designed specifically for applications requiring reliable performance in elevated voltage environments. Multilayer ceramic capacitors are fundamental passive components used across virtually every electronic system. They provide energy storage, filtering, decoupling, and signal coupling functions in circuit designs. The 2225 designation refers to the physical package size — a surface-mount component measuring 2.2mm x 2.5mm — making it suitable for compact, high-density PCB layouts where space is at a premium. This small form factor is particularly valuable in modern electronics where miniaturization is essential without sacrificing performance. The "HA" designation within this part number indicates this capacitor is engineered for higher voltage applications compared to standard multilayer ceramic capacitors. Engineers typically specify high-voltage MLCCs in power supply circuits, DC-link filtering, energy harvesting systems, and other applications where component voltages regularly exceed standard operating ranges. Industrial equipment, renewable energy inverters, automotive electronics, and telecommunications infrastructure frequently demand these higher-voltage rated components. The "221K" marking indicates the capacitance value and tolerance classification, placing this in the kilopfarad range. This capacitance level is common for decoupling and filtering applications, particularly in power distribution networks where engineers need to suppress voltage ripple and transient noise across a wide frequency range. AVX's High Voltage ceramic capacitor series is recognized for consistent dielectric properties, reliable performance across temperature extremes, and excellent long-term stability. These capacitors typically exhibit low equivalent series resistance (ESR) and low equivalent series inductance (ESL), characteristics critical for high-frequency switching circuits and fast-transient power delivery applications. Engineers might select the 2225HA221KAT1A over alternative capacitors when they require the specific combination of compact surface-mount packaging, high voltage rating, and the particular capacitance value. The AVX brand carries strong reliability credentials in industrial and mission-critical applications where component failure is not an option. This part is commonly found in industrial power supplies, renewable energy systems, test and measurement equipment, and aerospace/defense applications where performance specifications and quality standards are stringent. For applications demanding proven high-voltage ceramic capacitor performance in a compact package, the 2225HA221KAT1A provides a dependable solution with established field history across demanding industrial markets.
