Tantalum Capacitors

A tantalum capacitor, also known as tantalum electrolytic capacitor, is an electrochemical component used in a wide range of electrical and electronic devices. It is made up of a conductive oxide film placed on a tantalum metal electrode. It is one of the most dependable and widely used components in the electronic industry. It has low leakage current and high capacitance stability over a wide range of temperature and frequency.

The most common type of tantalum capacitor is the surface mount style. This type of capacitor is designed to be mounted directly on a printed circuit board (PCB) or other substrate. The application field of a T95Y476K6R3LZAL tantalum capacitor includes power supplies, audio and video equipment, and medical equipment.

Working Principle

Tantalum capacitors consist of two electrodes, an inner anode and an outer cathode. A dielectric layer (oxide film) is located between the electrodes and provides insulation. When current is applied to the capacitor, the anode is filled with positive charge carriers which are attracted to the negative charges on the cathode - this creates a voltage across the dielectric layer.

When a tantalum capacitor is in use, the dielectric layer is considered to be of high quality. This is because the dielectric layer has been heat-treated and is very stable. The downside is that tantalum capacitors have a higher equivalent series resistance (ESR) than other types of capacitors. This means that they may be less effective in filtering out noise or high frequency signals.

Typically, the voltage rating of a tantalum capacitor is lower than that of other capacitors. The maximum operating voltage for a T95Y476K6R3LZAL tantalum capacitor is typically specified as 3.3 volts. This means that the capacitors must not be subjected to voltages higher than the specified rating in order to ensure their safe and reliable operation.

Tantalum capacitors are very reliable components which offer a wide range of advantages, including good capacitance values and a very low self-inductance. However, due to the relatively high leakage current and the high ESR associated with this type of capacitor, it is important to ensure that they are used in appropriate applications.
