Tantalum Capacitors

Tantalum capacitors are electrolytic capacitors that are mainly used in high-density integrated circuits (ICs). They are often found on motherboards and in other modern electronics, and are used in a wide variety of applications. The capacitors provide a variety of useful services including power and signal conditioning, timing, energy storage, and shielding.

The specific part number 199D476X9020E6V1E3 is one type of tantalum capacitor, and is useful for a wide range of circuit designs. It has a maximum working voltage of 6 volts and is designed for applications with temperatures up to +105°C. The size of these capacitors is 15mm in diameter and 7.5mm in height, which helps to save space on a circuit board.

The construction of a tantalum capacitor involves two electrodes that are separated by an electrolytic material. One of the electrodes is formed as a layer of tantalum or other metal along the surface of the dielectric. This electrode is slotted to provide improved thermal and electrical performance. The dielectric material is usually barium- or tantalum-oxide or niobium-oxide and in some cases polymers.

The electrodes of the tantalum capacitor must be activated and polarized before use. This process is known as pre-formed or pre-conditioning. When a charging voltage is applied to the capacitor, an electrical charge that is used to form an electric field is created. This electric field causes electrolyte ions to migrate from the cathode to the anode, and as a result, an electrical double layer or capacitance is formed at the electrodes.

The capacitance of a tantalum capacitor is determined by its capacitance value. This is the product of its capacitance type, ESR (equivalent series resistance), and its equivalent series inductance (ESL). These parameters must be known for each capacitor before it can be used in a circuit.

Tantalum capacitors have many advantages over other types of capacitors such as polyester and aluminum electrolytic capacitors. First, their size is much smaller and space-efficient, which makes them ideal for use in high-density ICs. Another advantage is their high stability, as they have excellent temperature and voltage coefficients. In addition, they have a low equivalent series resistance (ESR) and equivalent series inductance (ESL), which helps to reduce power losses and noise in the circuit. Furthermore, they have a high energy density which can help reduce the size of the IC itself.

In conclusion, the specific model 199D476X9020E6V1E3 is a tantalum capacitors that is useful for many applications, such as power and signal conditioning, timing, energy storage, and shielding. It has many advantages over other types of capacitors, such as a small size, high stability, low ESR and ESL, and high energy density. This makes it an ideal choice for high-density IC designs.
