Tantalum Capacitors

Tantalum capacitors are widely used components in all electronic solutions, from low power portable applications to very high power medical systems. The capacitors can be used in two main applications: decoupling and charge storage. The M39003/03-2019/TR is one of the most popular tantalum capacitor series used in the industry today.

Application Field & Working Principle of M39003/03-2019/TR

The M39003/03-2019/TR tantalum capacitors are designed to provide a capacitance range from 0.1pF to 470pF. The capacitors are constructed with a sputtered oxide dielectric and a fused tantalum pentoxide or tantalum niobate dielectric. The capacitors also use a thick-film solderable termination or reflowed soldered connection, depending on the component.

The M39003/03-2019/TR tantalum capacitors can be used in a variety of different applications, including decoupling, filtering, smoothing, signal coupling, energy storage, and RF attenuating. The capacitors are also commonly used in battery powered devices due to their low leakage current and higher capacitance than other components.

The working principle behind a tantalum capacitor is similar to that of a ceramic capacitor. A tantalum pentoxide or niobate dielectric layer is sandwiched between two metal plates. When a voltage is applied across the plates, an electric field is created which causes electrons to be drawn to the negative plate, creating a stored charge or electric field. The stored charge remains even when the voltage is removed, allowing the capacitor to act as a filter or energy store.

Tantalum capacitors are also known for their excellent temperature stability and self-healing properties. The capacitors can withstand high temperatures and do not degrade rapidly with age or temperature. In addition, the dielectric layer is able to self-heal if it is damaged, making them very reliable and robust components.

Tantalum capacitors can be used in a variety of different applications and are a popular choice for mobile applications. The M39003/03-2019/TR series capacitors are available in a variety of sizes and capacitances and are trusted components used in many projects and applications around the world.
