The C1206C226Z9VAC-TU from KEMET is a 22\u00b5F 6.3V MLCC in a 1206 (3216 metric) package with Y5V dielectric and -20%\/+80% tolerance. The Y5V dielectric provides maximum capacitance per unit volume, making it suitable for bulk energy storage in low-voltage applications where tight capacitance tolerance is not required.<\/p>\n

The KEMET part numbering: C=MLCC, 1206=size, C=series, 226=22\u00b5F (22\u00d710\u2076pF), Z=-20%\/+80%, 9=6.3V, V=Y5V dielectric, AC=process code, TU=packaging. The Y5V (Z5U class) dielectric provides the highest CV density among Class II ceramics but with very wide capacitance variation over temperature (+22%\/-82%) and voltage. This makes it suitable for bulk decoupling where capacitance value is not critical, but maximum capacitance per unit volume is desired. The 1206 package provides adequate area for 22\u00b5F with reasonable reliability.","working_principle":"The C1206C226Z9VAC-TU uses KEMET's multilayer ceramic construction with Y5V dielectric, which is based on a modified barium titanate composition optimized for maximum dielectric constant (K). The Y5V formulation achieves K values of 10,000-15,000, enabling the very high 22\u00b5F capacitance in a small 1206 package. However, the high-K formulation comes with significant temperature and voltage dependencies: the capacitance can drop by up to 82% at the temperature extremes and decreases further with applied DC voltage. The inner electrodes (typically Ni) are alternately connected to the two end terminations (Cu\/Ni\/Sn). The wide -20%\/+80% tolerance reflects the inherent variability of the Y5V dielectric formulation.","pin_description":"
