Tantalum capacitors are important components in electronic circuits. The M39003/03-0286H tantalum capacitor is a polarized, hermetically sealed, molded case, solid, general-purpose, miniature capacitor that is designed for the use in a variety of electronic applications. It is available in a wide range of values, from 0.1 μF to 470 μF with a voltage rating of 4 Vdc to 50 Vdc. The capacitor is designed to meet the requirements of Military Specification MIL-C-11015E.

The M39003/03-0286H tantalum capacitor consists of a wound tantalum anode, a cathode lead wire, a dielectric layer, an electrolyte, a glass-to-metal seal, and metal end seals. The anode and cathode leads are connected to the capacitor body to form the capacitor\'s terminals. The dielectric is a solid tantalum pentoxide material that has a high dielectric constant. The electrolyte is usually a mixture of manganese dioxide and dichlorosilane. The glass-to-metal seal provides hermeticity and insulates the anode and cathode leads from the capacitor body.

The M39003/03-0286H tantalum capacitor has a wide range of applications, ranging from bypass capacitors to bypass diodes. It is often used as a filter capacitor in power supply applications, such as power amplifiers and voltage regulators. It is also used in communication systems, digital logic circuits, RF amplifiers, and medical equipment.

The working principle of the M39003/03-0286H tantalum capacitor is based on the diffusion of ions through the dielectric layer. This phenomenon is known as electrolytic conduction, and it takes place when an electric field is applied. As the electric field increases, more ions are forced through the dielectric layer, and the capacitance increases. Over time, the ions may accumulate on one side of the dielectric layer, causing the capacitance to decrease. This phenomenon is known as dielectric polarization, and it can reduce the capacitance over time.

The M39003/03-0286H tantalum capacitor is a reliable component that is suitable for a wide range of applications. It is a reliable, durable, and long-lasting component that can withstand temperatures ranging from -55°C to 125°C. Its high voltage rating and low ESR make it an ideal choice for power supply applications, and its solid construction makes it suitable for use in harsh environments. It is a cost-effective solution for a variety of applications.
