Tantalum Capacitors

Tantalum capacitors are a form of electrolytic capacitor, which is one of the most common options for electronic equipment. They are identified by their capacitance, which is their ability to store a charge, and an impedance, which measures how much energy it takes to charge and discharge them. Both these values must be taken into account when deciding which tantalum capacitor to use.

Manufactured by Vishay, the M39003/01-2882H capacitor is a low ESR (Equivalent Series Resistance) device ideal for applications which require stable operating temperatures. It also has a highly reliable design due to its lengthy life and high tolerance to environmental conditions.

Application Field

The M39003/01-2882H capacitor is mainly used in various types of industrial and medical equipment, such as computer systems, video equipment, and medical electronic equipment. It is also suitable for automotive, military, and aerospace applications.

This tantalum capacitor is preferred for its low ESR and high voltage ratings. It has the same physical dimension as the low ESL (Equivalent Series Inductance) ceramic capacitors, making it easy to utilize in switching power supplies as well as for high-speed switching applications.

Other application areas include decoupling, which is used to reduce power supply noise; snubber designs, which help reduce the effects of electrical transients in a power distribution system; and power supply noise filtering.

Working Principle

The M39003/01-2882H capacitor works by storing an electrical charge within its own polymer dielectric material, which is held between two electrodes. This type of capacitor is made up of two sets of plates - a positively charged and a negatively charged one. When a voltage is applied across the capacitor, electrons are drawn to the negative plate, and holes are created on the positive plate. This generator of charges is known as an electric field.

When the electric field is strong enough, the potential force of the charged particles as they move between the two plates creates a tension in the dielectric material, thus creating an electrical current. This current is known as capacitive reactance, and it can be used to regulate the amount of current passing through a circuit.

The M39003/01-2882H capacitor also has a long life expectancy due to its polymer dielectric material, as well as its wide operating temperature range. Its high voltage capability make it great for applications that use high-q stages, and its low ESR and ESL make it suitable for low-voltage power-conditioning circuits.
