12065A2R2CAT4A

The AVX 12065A2R2CAT4A is a thin-film chip capacitor designed for precision applications requiring stable, reliable performance in compact form factors. This component belongs to AVX's established family of surface-mount capacitors intended for use in demanding industrial and commercial electronics where film technology offers advantages over ceramic alternatives. Thin-film capacitors are constructed using deposited film dielectrics, which provide inherently low distortion, excellent frequency stability, and superior reliability characteristics compared to multilayer ceramic capacitors. These properties make them particularly valuable in analog signal conditioning, precision measurement circuits, audio equipment, and power supply filtering applications where signal integrity and long-term performance consistency are critical. The 12065 designation indicates a 1206-sized package (approximately 3.2mm × 1.6mm), a standard surface-mount form factor widely used in modern PCB designs. This size offers a practical balance between component density and handling ease for both automated assembly and manual rework scenarios. The compact footprint allows designers to integrate precision filtering and coupling functions without consuming excessive board real estate, making it suitable for space-constrained applications in industrial control systems, instrumentation, and communications equipment. The "2R2" portion of the part number indicates a capacitance value of 2.2 microfarads, placing this component in the mid-range for film capacitor applications. This value is commonly used for DC blocking, AC coupling, timing circuits, and low-frequency filtering where film technology's stability characteristics provide measurable advantages. The CAT4A designation refers to AVX's specific construction and performance class for this product line, denoting particular tolerances and temperature characteristics suitable for industrial operating environments. Engineers typically specify thin-film capacitors like the 12065A2R2CAT4A when applications demand low equivalent series resistance, minimal frequency-dependent behavior, predictable aging characteristics, or superior performance in temperature cycling environments. Unlike ceramic capacitors that can exhibit significant capacitance variation with temperature and applied voltage (piezoelectric effects), thin-film devices maintain consistent electrical characteristics across operating ranges. This makes them essential for precision analog applications, impedance matching networks, and circuits where component stability directly impacts system performance. The AVX manufacturing heritage and established presence in industrial markets ensure that this component integrates readily into supply chains with well-documented performance history. Designers selecting this specific part number can rely on consistent film technology benefits, proven manufacturing quality, and compatibility with standard surface-mount assembly processes used throughout industrial electronics manufacturing.
