Tantalum Capacitors

M39003/09-0311/TR Application Field and Working Principle

Tantalum capacitors are a type of capacitor used in electronic circuitry. Component of a basic type, they consist of two metal plates separated by an insulating material, most commonly tantalum oxide or mica. Tantalum capacitors are widely used in automotive and consumer electronics, as well as in military and aerospace applications.Tantalum capacitors have a number of advantages over other types of capacitors. Due to their small size, they are ideal for use in compact systems and can help minimize overall board size, allowing designers to create smaller products. Tantalum capacitors also have a higher surge current rating and higher voltage rating than aluminum electrolytic capacitors, which makes them suitable for power supply decoupling applications. Furthermore, they have stable performance over wide temperature ranges, from -55°C to 125°C, and can operate up to 180°C in some cases.The M39003/09-0311/TR is a small-size, hermetic encapsulated, tantalum capacitor. It is designed specifically for demanding military and aerospace applications where high performance and reliability are required. It offers a high working voltage of up to 200 volts and an operating temperature range from -55°C to 85°C.The M39003/09-0311/TR tantalum capacitor is composed of three key components. The first component is a tantalum anode, which is made from the metal tantalum. The second component consists of a dielectric layer of tantalum pentoxide and the third component is a manganese dioxide cathode. The anode and cathode are connected via an electrolyte to form a solid capacitor body.The working principle of the M39003/09-0311/TR tantalum capacitor is simple. When an electric current passes through it, an electrostatic field forms between the anode and the cathode. This field increases as the current passes through, and as the voltage applied to the capacitor increases, the electrostatic field increases even further. As the electric field continues to increase, it creates an opposing electrostatic force which prevents any further increase in voltage. This is how the capacitor acts as a voltage stabilizer, allowing current to flow while preventing any catastrophic voltage fluctuations from overloading delicate components.In addition to its voltage regulation benefits, the M39003/09-0311/TR tantalum capacitor offers other advantages as well. It has a good response time, and is able to handle higher frequencies with less distortion. It also has a lower equivalent series resistance (ESR) than other types of capacitors, making it ideal for applications that require high frequencies. Furthermore, it is resistant to vibration, which makes it suitable for use in harsh environments.Overall, the M39003/09-0311/TR tantalum capacitor is an ideal choice for military and aerospace applications due to its high performance, reliability, and voltage regulating capability. Its small size, wide temperature range, and vibration resistant properties make it well suited for use in high vibration environments. Furthermore, its low ESR makes it an excellent choice for use in high frequency applications, and its capacitance stability over extended temperature and frequency ranges make it well suited for power supply decoupling applications.
