Tantalum Capacitors: M39003/09-0237H Application Field and Working PrincipleTantalum capacitors are becoming increasingly popular in today’s electronic industry due to their advantages over other types of capacitors such as ceramic, aluminum electrolytic and other types of capacitors. Tantalum capacitors are made of a tantalum alloy which contains at least 50% of the metal. The other material used in the composition of the capacitor is a manganese dioxide material. This two material combination produces a higher energy density than any of the other capacitor types. The tantalum capacitor model M39003/09-0237H is a hermetically sealed, solid analog capacitor with a rated voltage of 350 to 450 VDC. This product is available in three different sizes that range from 0.25 to 0.875 inches in overall diameter. This series of capacitors utilizes hermetic silicon sealed technology and a high temperature tantalum anode, with lead based metal caps. This combination creates a capacitor with a high operational frequency for use in all types of applications. The working principle of a tantalum capacitor relies on the movement of charges between layers of two materials across a medium called an electrolyte. The capacitors have two plates made of conductive metal, and a non-conductive material between them which acts as a separator or dielectric. In a tantalum capacitor, one of the plates is made of tantalum, and the other plate is another metal. The electrolyte material used in a tantalum capacitor is usually a manganese dioxide or a polycarbonate material. When the plates are connected to a power supply, a voltage is applied across them which causes a charge to flow from one plate to another. As electrons pass from one plate to the other, they are stored in what is known as the electric field, or capacitor. The stored energy can then be released back to the power supply when an opposite voltage is applied. Tantalum capacitors are widely used in a variety of electronic circuits. They are particularly popular in high frequency circuits, due to their higher energy density and ability to handle high temperatures. They are also used in pass filter networks, active and passive filters, and pulse circuits. Due to its high capacity and temperature-resistant design, M39003/09-0237H is suitable for a wide variety of applications. This capacitor is used in high frequency circuit designs as well as in interfaces for high-end cell phone, notebook, and smart device components. This model can also be used as a base capacitor in an industrial power supply, and is ideal for autopilot circuitry and other safety instrument systems, as it provides a stable voltage supply. Overall, the M39003/09-0237H is an excellent choice for digital and high-end analog circuits, due to its solid design and ability to handle high temperatures. With its excellent capacitance and temperature-resistant properties, this tantalum capacitor is an ideal choice for a wide range of applications.
