Introduction to M39003/09-0382/TR

Tantalum capacitors, sometimes referred to as “tantalums”, are an electronic component designed to store electrical energy in the form of a capacitor. They were initially developed during World War II by English physicist William Lickley, and they have been used in a broad range of applications since then. M39003/09-0382/TR is a type of Tantalum Capacitor manufactured by AVX, and it is one of the most widely used capacitors in the world.

Applications of M39003/09-0382/TR

M39003/09-0382/TR is mainly used for high frequency and demanding applications, where its excellent characteristics are essential. Primarily, they are used in a variety of communication devices, including cellular phones, portable music players, and computers. They are also used in medical devices and equipment, such as defibrillators and pacemakers. Other than that, M39003/09-0382/TR are extensively used in industrial applications. Due to their excellent temperature characteristics, low ESR, and high ripple current ratings, they are used in applications such as power supplies, motor drives, and solar power systems. Moreover, they are also used in the automotive industry, in the form of filters, noise suppression capacitors, and voltage regulators.

Components of M39003/09-0382/TR

M39003/09-0382/TR is made up of a solid core of silver mica substrate material, surrounded by a dielectric material. The silver mica substrate is held together in place by a special binder, which acts like a suspended electrode. The dielectric material is usually made of a tantalum oxide layer, which gives M39003/09-0382/TR their unique characteristics, such as low losses and low inductance. The M39003/09-0382/TR is further characterized by temperature coefficient ratings, ripple current ratings, and capacitance ratings. The capacitance rating indicates the maximum capacitance that the capacitor can store. The ripple current ratings indicate the maximum amount of current that the capacitor can handle, and the temperature coefficient ratings indicate how much the capacitance will change with a change in temperature.

Working Principle

The working principle of M39003/09-0382/TR is fairly straightforward. When an electric voltage is applied across the terminals, it causes a positive charge to be built up on one side of the silver mica substrate and a negative charge on the other side. This sets up an electric field between the two sides of the silver mica, thus creating a potential. Depending on the capacitance rating, when a high enough potential is built up, electric current will flow through the capacitor, which is known as charging the capacitor. During normal operations, the capacitor will store a certain amount of charge, and when that amount is exceeded, the capacitor will start to discharge the charge it has stored.

Conclusion

M39003/09-0382/TR is a type of Tantalum Capacitor made by AVX. It has a variety of applications, ranging from medical devices and equipment to industrial power supplies and motor drives. It is composed of a silver mica substrate encased in a tantalum oxide dielectric material. Its working principle is based on storing a charge when a voltage is applied across its terminals. Overall, M39003/09-0382/TR is one of the most reliable and efficient capacitors on the market.
