Tantalum capacitors are an essential component in a myriad of applications in the electronics industry. From cell phone batteries to electric vehicles, they are a critical element in the reliable operation of many electrical systems. The specific model denoted by the number 199D475X0020B1V1E3 is one example of a popular and widely used tantalum capacitor. This article will explore the typical applications and working principles of this capacitor.A tantalum capacitor is a type of electrolytic capacitor, an electronic component which makes use of a tantalum metal film to provide a high-capacity storage of electric energy between two electrodes. When an electric charge is applied to this capacitor, electrochemical reactions occur in the tantalum film which cause it to store electric energy. This energy is then freely available to be drawn from the capacitor and used as an electrical current.A tantalum capacitor’s capacity is typically measured in microfarads (F). The 1999D475X0020B1V1E3 model capacitor has a capacity rating of 0.025 F, which makes it suitable for a wide variety of applications. Some of the most common applications for this type of capacitor include:

• Filtering power in electrical circuits, such as those found in mobile phones and computers
• Supplying short-term voltage stability to power supplies in equipment such as audio amplifiers and mixers
• Storing charge in order to power remote control devices and other similar items
• Acting as a voltage-limiting resistor in television sets and other low-voltage electronic equipment

Beyond its use in consumer electronics, the 1999D475X0020B1V1E3 model capacitor can also be found in medical equipment, laser printers, and measuring instruments. It is a popular choice for many industrial and automotive applications due to its reliable performance and long operating life. In addition to its practical applications, the 1999D475X0020B1V1E3 tantalum capacitor also has certain benefits over other types of capacitors. The most notable of these is its low temperature coefficient, which allows for smoother operation in temperatures ranging from - 40 °C to 85 °C. This capacitor also offers excellent stability, higher leakage current, and better frequency and ripple current characteristics than many other models.The working principle of the 1999D475X0020B1V1E3 tantalum capacitor is highly dependent on the physical structure of the device. Inside the capacitor, tantalum metal is formed into a thin film with two electrodes attached to opposite sides. When an electric charge is applied to the capacitor, electrochemical reactions between the metal film and its two electrodes occur, causing it to store the charge and acting as a conduit for electricity. The resulting current is dependent on the voltage and capacitance of the capacitor, and can be manipulated in order to produce the desired effect.Thanks to the reliable performance and low cost of tantalum capacitors, such as the 1999D475X0020B1V1E3 model, these components are widely used in many different types of electronic equipment. From consumer electronics to medical equipment and automotive components, these capacitors are a popular choice for many applications. Their physical structure, capacity rating, temperature coefficient, and other characteristics make them a highly efficient and cost-effective way to store and conduct electric energy.
