Tantalum Capacitors: M39003/03-0484/TR Application Field and Working Principle

Tantalum capacitors are widely used in many electronic equipment thanks to their high dielectric strength, long life, low leakage and self-healing features. The M39003/03-0484/TR is manufactured by the JT Connector Corp, and it is a popular model of tantalum capacitors used in a variety of electronic products. This article will discuss the application field and working principle of this capacitor and its advantages when compared to other technologies.

Application Field

The M39003/03-0484/TR is a surface-mount tantalum capacitor, which means that it is designed to be installed on the surface of a PCB board. It is available with a wide range of capacitance values from 2.2µF to 330µF and with a variety of voltage ratings up to 50V. Due to its small size and low cost, this capacitor is often used in consumer electronics, computers and other mobile devices. It is especially suitable for applications that require high-density integration of capacitance, such as power supplies, filters and high frequency communication circuits.

Working Principle

The M39003/03-0484/TR is a polarized capacitor, which means that it has an anode and a cathode. The anode is made from a tantalum pellet with a highly porous surface, while the cathode is a manganese dioxide coating which provides the capacitor with its charge-storing properties. When electric current passes through the capacitor, the manganese dioxide coating is positively charged, while the tantalum pellet is negatively charged. The stored charge, expressed in farads, is proportional to the applied voltage.

A significant feature of the M39003/03-0484/TR is its high dielectric strength, which determines the amount of electric field it can withstand without breakdown. This helps ensure a longer lifetime for the capacitor, as it is more resistant to sudden voltage surges. Furthermore, the capacitor has self-healing properties which helps to protect it from overload and damages.

Advantages Compared to other Technologies

Tantalum capacitors have several advantages compared to other capacitor technologies, such as aluminum electrolytic capacitors and ceramic capacitors. First, they offer higher capacitances for a given physical size, which means that more capacitance can be integrated into a smaller board space. In addition, they also have a longer lifetime and are more stable over a wider temperature range. Finally, they have a lower ESR (equivalent series resistance) meaning that less power is lost when current passes through.

In conclusion, the M39003/03-0484/TR is a versatile tantalum capacitor which offers a combination of high capacity, long lifetime and high dielectric strength. It is an ideal choice for a wide range of applications which require high performance and reliability, such as consumer electronics, computers and mobile devices.
