Tantalum capacitors are a type of electrolytic capacitor—here referring to the solid-electrolyte type—which uses tantalum as its anode, and an oxide film formed on the surface of the tantalum powder as its dielectric. The oxide film is formed from two ions, Ta5+ and O2-; they are formed during the manufacturing process of the capacitor, which involves heating so as to create the oxide. These two ions, along with the tantalum anode, form an electrical barrier, which creates a space between the capacitor\'s anode and cathode. This barrier then prevents the flow of electrons through the surface of the capacitor, allowing charge to build up on either side of the barrier.
M39003/03-3072/HSD is a type of tantalum capacitor with a temperature rating of -55° C to +125° C, with a voltage rating of 10V DC and a capacitance range from 0.1μF to 2200μF. The capacitor is constructed from tantalum powder impregnated with a solid electrolytic compound. The construction process creates an oxide film on the surface of the powder, which acts as the capacitor’s dielectric. This dielectric layer then blocks the flow of electrons through the capacitor, which allows charge to build up on either side of the oxide film.
The application of a tantalum capacitor like M39003/03-3072/HSD is quite broad, ranging from voltage filtering and buffering to filtering for energy storage systems and motor controls. Its temperature and voltage ratings make it suitable for high temperature applications such as down-hole drilling, audio amplifiers, and automotive applications. The capacitor also excels in high humidity environments, such as large scale transformers and irrigation systems. The capacitor is also ideal for applications requiring a large capacitance value in a small package; its range of 0.1uF to 2200uF allows flexibility in design, and its size allows it to fit into many tight spaces.
In operation, the M39003/03-3072/HSD capacitor works similarly to other electrolytic capacitors. When a voltage is applied to the anode and cathode, charge begins to build up on the capacitor\'s plates. This charge then forms an electrical field across the tantalum/oxide dielectric barrier—the larger the voltage and capacitance of the capacitor, the greater the charge that can be stored. When the voltage is removed, the subtle electric field that has built up across the dielectric barrier begins to dissipate, which then allows the capacitor to store the charge and release it steadily over time. This makes tantalum capacitors essential components in many electronics, as they allow for precise voltage control.
The M39003/03-3072/HSD tantalum capacitor is an important component for a variety of applications, ranging from high temperature and high humidity environments to small spaces with large capacitance requirements. Its construction and operating principle allows the capacitor to build and dissipate electrical fields quickly and accurately, making it an effective choice for many applications.
