Tantalum Capacitors

Applying the finishing touches to a product is no small thing. The slightest detail can make all the difference between a good product and a great one. This is especially true of electronics, as the electrical engineering field provides such a large library of component options for creating a successful product. Note that no single component should ever be singled out, as each has its own purpose and importance, however some of these parts more noticeably than others. To that effect, many electronic engineers rely on Tantalum Capacitors to provide the circuit with some stability. This article will examine one such capacitor, the M39003/01-7292/TR, and explain its application field and working principle.

Tantalum capacitors are a type of electrolytic capacitor, as their operation is based on the use of a electrolytic material called tantalum pentoxide. This material is applied to two opposing metal plates, separated by a thin film of the electrolyte, otherwise known as the dielectric. Lastly, the capacitor is usually covered with a plastic sleeve for protection.

The M39003/01-7292/TR capacitor is produced by the M39003 family, and is a radial-leading component with an axial wrap-around case. The 7292 designation stands for a 10µF (microfarad) capacitance, 10 volt operating voltage, and the type of dielectric is denoted by the “TR”. In this case, the TR stands for tantalum coating, and indicate that the M39003/01-7292/TR capacitor is a conventional, non-solid device.

The M39003/01-7292/TR capacitor offers excellent performance in a variety of situations, from noise suppression and low bag ripple to high ripple current and high-frequency applications. This is due to the metallic construction of the capacitor, which makes it a far better conductor than ceramic chips or other non-metallic constructions. The M39003/01-7292/TR capacitor is also highly durable, and can withstand temperatures as high as 125°C (257°F).

The working principle of the M39003/01-7292/TR capacitor is essentially the same as any other electrolytic capacitor. When the capacitor is under an applied voltage, electrons flow from one plate of the capacitor to the other, creating a charge on each plate. The charge on the plates creates an electric field, resulting in a resistance to any further movement of electrons. The voltage across the plates is known as the capacitance, and it determines the amount of charge that can be stored on the plates.

The tantalum coating of the M39003/01-7292/TR capacitor provides a particularly high degree of durability. As well as being able to withstand high temperatures, the coating also provides a barrier against humidity and oxidation. This makes the M39003/01-7292/TR capacitor ideal for use in high ambient temperature environments, such as in automotive applications and for controlling power supply ripple and noise.

The tantalum capacitors have been widely adopted in a range of applications, owing to their numerous advantages such as low cost, high volumetric efficiency, and low equivalent series resistance. They may be used in low-noise circuits, where their low ESR values provide the necessary clean current pulses. They are also ideal for use in applications where the power supply is often affected by large transients or rapid voltage swings, as they can quickly absorb and redistribute the power.

In summary, tantalum capacitors such as the M39003/01-7292/TR belong to a very versatile family of electronics components. The M39003/01-7292/TR capacitor is an excellent choice for applications where high temperature, durability, and high-ripple current are required and offers a good balance of reliability and performance.
