Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which are polarized electrochemical elements that store electrical charge. They are commonly used in high-density, compact electronic applications and for many life-critical applications such as medical devices.

Tantalum capacitors are generally constructed from a tantalum slug and a pressed powder dielectric material, made from a variety of elements such as manganese dioxide, and a shell that functions as the negative terminal. Additionally, they are typically in cylindrical cans with molybdenum terminals, epoxy and glass seals, and a rubber cap.

The unique characteristic of tantalum capacitors is their small size and lightweight, making them ideal for use in portable devices such as cell phones, laptops and tablets. Furthermore, they have excellent high temperature performance, good shelf life and a wide working temperature range.

The basic design associated with tantalum capacitors is the199D225X0016A2A1. This design is anSC-70, or small outline package. The 199D225X0016A2A1construction combines a molded epoxy, a molybdenum anode terminal, and a substrate made from molybdenum or tantalum. The capacitance of the 199D225X0016A2A1tantalum capacitor is 16μF and its rated dc voltage is 25 volts.

Tantalum capacitors are non-polarized, which means that current can flow in both directions through the device. This feature makes them ideal for applications that require a direct current (DC) source. Additionally, they can also be used in AC circuits as they are resistant to DC bias.

The working principle of tantalum capacitors is based on the electrochemical principles of electrolytic material, which is why they are also referred to as electrolytic capacitors. In this type of capacitor, the electrical energy is stored in the form of an electric field established between two metallic plates that are located opposite each other within the capacitor housing.

When a voltage is applied to the plates, an electric field builds up between the plates. This electric field creates a storage cell for the electric charge, and thus, the capacitance of the capacitor is accomplished. The capacitance of the tantalum capacitor increases as the amount of material between the plates increases.

Because of their small size, low ESR and inherent non-polarized design, tantalum capacitors are well suited for use in applications such as signal processing, audio/video equipment, LED/LCD display circuits, and communications systems, among others.

Tantalum capacitors are also used in many military and space applications that require high performance, such as satellite systems, radar systems, and missile guidance systems. The advantages of these components in such applications include their small size, low ESR, and high reliability.

In conclusion, tantalum capacitors are highly useful in many electronic applications due to their small size, low ESR, and non-polarized design. The 199D225X0016A2A1 capacitor is a great example of the type of design used for a high-density, small outline package. As such, tantalum capacitors can be used for a variety of applications, from consumer electronics to military and space equipment.
