Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electronic component similar to a battery. They are typically made up of two metallic plates, one made of tantalum and the other of an oxide material, which are connected by an electrolyte and housed in a metallic can. The two plates form a capacitor, permitting the flow of electrical charge while storing energy. The dielectric oxide material of the capacitor enables the tantalum plates to maintain their electrical potential, while at the same time, the capacitor can be recharged.

The capacitor\'s plate structure, known as the anode and cathode, is designed to operate either in an AC or DC circuit. The anode and cathode are designed to draw current, depending on which direction the voltage is applied. When voltage is applied to the anode of the capacitor, it draws current, thus storing energy for a later time. When the voltage is reversed, the cathode draws current, releasing energy stored by the capacitor.

TH3B475M020D1900 Application Field and Working Principle

The TH3B475M020D1900 is a type of tantalum capacitor manufactured by Murata. It is a radial leaded surface mount device that comes in a variety of capacitance ratings ranging from 4.7 μF up to a maximum of 1.2F. It also features a maximum voltage rating of 16V and a rated temperature range of -55°C to +125°C, allowing it to be used in a variety of industrial applications. The TH3B475M020D1900 is a low-ESR (equivalent series resistance) capacitor, meaning that it is able to provide stable electrical characteristics when used in high-frequency circuits.

The TH3B475M020D1900 is a polarized capacitor, meaning that the anode terminal must be connected to the positive terminal of the circuit, and the cathode terminal must be connected to the negative terminal. This is due to the fact that the electrolyte used in the construction of the capacitor has different densities and electrolytic capacities between the anode and the cathode. When voltage is applied to the capacitor, an electrochemical reaction occurs, allowing for the transfer of electrical charge across the electrolyte and the capacitor\'s two plates.

The TH3B475M020D1900 is primarily used in SMT (Surface Mount Technology) applications, where it is integrated into a printed circuit board. It is a good choice for applications requiring stable performance under harsh environmental conditions, such as extreme temperatures and power cycling.

The TH3B475M020D1900 is a versatile capacitor, offering a wide range of capacitance ratings, voltage ratings, and temperature ranges. Its low ESR characteristics make it suitable for high-frequency circuits, while its robustness and durability make it a good choice for industrial applications.
