Tantalum capacitors, or tantalum electrolytic capacitors, are a type of capacitor that is characterized by its high electrical breakdown strength, low dielectric loss and small size. The 199D474X9050A2V1 is a particular model of tantalum capacitor whose application field and working principle are described below.

Tantalum capacitors are typically used for various electronic circuits such as signal processing, power management, and product design. Most common applications include signal coupling, signal accuracy, bypass, timing, and power management. In signal coupling, the capacitor maintains signal accuracy as it blocks DC bias voltage but allow signal frequencies to pass. Its bypass effects help reduce noise and control voltage decoupling in signal accuracy applications while its timing functions provide consistent time delays in circuits and when used in pulse generators. Moreover, tantalum capacitors are ideal for power management circuit in critical circuits, where their low parasitics and low DC resistance are the primary benefits.

The working principle of tantalum capacitors relies on the electrolyte and a bridge between the cathode and anode terminal. A tantalum oxide (Ta2O5) layer is formed over the anode and acts as the dielectric layer. In operations, the capacitor is initially charged on the anode with a large current as the anode is connected to the higher voltage. This process allows electrons to pass through the electrolyte and to form a highly conductive Ta2O5 layer on the anode. This ultimately creates a capacitor that allows current to flow from one terminal of the capacitor to the other through the bridge and electrolyte.

The 199D474X9050A2V1 is a particular model of tantalum capacitor that offers high volumetric efficiency while providing considerable capacitance across several temperature ranges. This capacitor has a nominal capacitance of 47 μF and its ESR is rated as 6mΩ. It also offers excellent dielectric absorption and is capable of handling voltages up to 6.3V.
