Tantalum capacitors are electronic components made with a tantalum metal alloy, typically manganese dioxide, which serve as an electrode and electrolyte. Tantalum capacitors are widely used in many electronic devices, such as mobile phones and computers. They are small, cost-effective, and offer a wide range of performance characteristics.

The specific part 199D105X9016A1V1 is a surface-mount capacitor which utilizes a tantalum-based system. This device is a non-polarized capacitance element, meaning it does not require an electrical potential to function. Its structure is based around a foil etched tantalum metal sheet which serves as an electrical insulating medium between the two electrodes. The metal sheet is then filled with an electrolyte, usually manganese dioxide or similarly treated MnO2.

The main application field of part 199D105X9016A1V1 is energy storage, as it is capable of storing electrical energy for a long period of time. Tantalum capacitors are particularly useful for applications with higher voltages, as their high breakdown voltage and low leakage current make for reliable operation. Some standard applications include direct-coupled amplifier stages, decoupling applications, and charge pumps.

The working principle of tantalum capacitors relies on their unique construction. The foil provides the tantalum capacitor with its electrical insulation, ensuring that no current leaks out before the required voltage is reached. As the voltage increases, an electrical current flows between the two electrodes, which may be either an anode, or an electrolyte. This current travels through the electrolyte, which acts as a medium for the voltage to jump across. The current disrupts the structure of the electrolyte, providing further insulation to the capacitor.

The voltage across the capacitor is then determined by the physical properties of the electrolyte, such as its capacitance, insulation resistance, and the temperature at which the device operates. The actual output of the capacitor is a product of the input voltage, capacitance, and the insulation of the electrolyte.

Since part 199D105X9016A1V1 is a surface-mount tantalum capacitor, it can be used in multiple electronics projects. Its use is generally limited to energy storage and decoupling applications due to its high capacitance and low 220nH inductance. With its small size and high energy storage, this tantalum capacitor is an excellent choice for various portable electronics, including mobile phones and other handheld devices.
