Tantalum Capacitors: M39003/01-3069H Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are one of the most widely used types of capacitors in the electronics industry today. They are used in a wide variety of applications, from power supplies, motor control, and switch-mode power supplies to RF and microwave circuits. The M39003/01-3069H tantalum capacitor is a popular type of capacitor used in these applications. Tantalum capacitors are constructed from a tantalum metal powder pressed into a “pellet” shape. A layer of oxide film is then created on the surface of the pellet which serves as dielectric material, much like a standard ceramic capacitor. A second metal layer is then applied which acts as the cell’s electrodes. This combination of materials makes these types of capacitors particularly useful for applications demanding a high capacitance value in a small package. The M39003/01-3069H tantalum capacitor is mainly used in power supply applications to provide a stable voltage supply and to filter out noise. It provides discrete capacitance values in a very small package. This particular type of capacitor is available in a variety of values, ranging from 1µF to 68µF. It is designed to operate over a wide temperature range, from -55°C to +125°C, and its rated voltage is between 4V and 16V. It also features superior temperature change characteristics and low impedance at high frequencies. In terms of working principle, the tantalum capacitor employs the same capacitance mechanism as a ceramic capacitor. When a voltage is applied between the terminals of the capacitor, electrical charges are stored in the tantalum pellet. The oxide layer acts as the dielectric material that separates the negative and positive charges on the surfaces. By increasing the applied voltage, the amount of charge that can be stored on the capacitor increases, and the higher level of charge creates an electric field between the two electrodes. This is how the M39003/01-3069H capacitor stores charge and filters out noise. Overall, the M39003/01-3069H tantalum capacitor is one of the most popular types of capacitors available today. It is widely used in applications requiring a low-profile, high capacitance in a small size. It is highly reliable, offers a wide range of temperature and voltage ratings, and its superior performance characteristics make it perfect for power supply, RF, and microwave circuits.
