The TAJV227M016RNJ is a solid-state, surface-mount (SMD) tantalum capacitor manufactured by Kyocera AVX. It is a bi-polarized device, rated for an operating voltage of 16 volts DC, with a capacitance of 220 microfarads (µF), and a tolerance of 20%. This capacitor is non-polarized, meaning its wide capacitance range can be used in a wide variety of circuit designs. Used in high-end audio applications, these capacitors are designed to block DC and provide a low impedance path to AC signals. They are also suitable for refined power-supply circuits, as they help filter out unwanted ripple, noise, or any other line or frequency noise.
