Tantalum Capacitors

Tantalum capacitors are solid electrolytic capacitors that use the anode material tantalum and have a non-solid electrolyte. The most common tantalum capacitors are marked with a three digit code, such as M39003/01-8067H. These capacitors offer high capacitance in a small package, making them ideal for applications where space is limited.

Application Field and Working Principle

M39003/01-8067H capacitors are used in many applications where a relatively small amount of capacitance is needed. They are ideal for high-frequency signal conditioning, audio amplifiers, and RF amplifiers. The principle of operation of these capacitors is based on the “valence” of the tantalum oxide film and the ability of this material to store electric charge.

When a voltage is applied across the plates of the M39003/01-8067H capacitor, the electrons in the tantalum oxide film are attracted to the anode plate and form a conformal layer that serves as the dielectric. The electrodes of the capacitor alternate between positive and negative charges, creating the capacitance necessary to store the energy. The amount of capacitance is determined by the surface area of the electrodes, the distance between them, and the thickness of the dielectric.

M39003/01-8067H capacitors provide a very stable voltage output and have low manufacturing cost. This makes them ideal for applications that require high reliability. They also have low leakage current and a high self-healing capability, meaning that the capacitors can withstand a high voltage before they are damaged. The use of a solid dielectric, such as tantalum oxide, also ensures a high dielectric strength and high temperature stability.

M39003/01-8067H capacitors are available in a variety of sizes and packages. They are typically used to store energy for a short period of time, making them ideal for use in switched mode power supplies, high frequency pulses, and low power DC-DC converters.

Tantalum capacitors, such as the M39003/01-8067H, are a reliable and cost-effective solution for a wide range of applications. They provide high capacitance in a small package, making them ideal for use in applications where size and space are critical factors. Their low manufacturing cost and high performance make them a popular choice for many applications.
