Tantalum Capacitors

T495B225M035ZTE1K5 is a tantalum capacitor, a form of capacitive device used mainly in electrical circuits to store energy temporarily for a variety of uses. This particular tantalum capacitor provides a high energy density compared to other types of capacitors, making it well suited for dense packaging designs. With a capacitance value of 0.225 microfarads, and a voltage rating of 35 volts, this capacitor has a wide range of applications.

Application Fields

T495B225M035ZTE1K5 is used in many different applications, ranging from low-sensitivity circuits for automotive, communications, and industrial systems, to more sensitive applications such as audio frequency circuits and resonator circuits, where its stability is essential. It is also used in DC-DC converters as well as integrated power components.

In audio frequency circuits, tantalum capacitors provide a great deal of benefit due to their excellent frequency response, low distortion, and superior performance in high-temperature environments. Their use in resonator circuits is based on their ability to act as a reliable frequency-determining device even in circuits with small physical dimensions.

In automotive applications, T495B225M035ZTE1K5 is often used in combinations with other electronic components in order to provide gate voltage for transistors, and to build up and hold gate charge from one circuit to another. In communication systems, these capacitors are used to fine-tune the frequency of signals within transceivers, and are also used to smooth out fluctuations in voltage levels.

Working Principle

In order to understand how tantalum capacitors work, it\'s necessary to understand the process of capacitance. A capacitor is an electronic component that stores energy in the form of an electric field. It consists of two conducting plates, separated by an insulating material, called a dielectric.

When a voltage is applied to the two plates, an electric field is formed between them, forming a capacitance. The amount of capacitance depends on the size, shape, and thickness of the dielectric material, and the area of the two conducting plates. The amount of capacitance generated is also influenced by temperature.

The electrodes of a tantalum capacitor are made of an oxide-coated solid tantalum metal, as opposed to the plastic film of other types of capacitors. The oxide coating is eventually used as the dielectric material, so the size and shape of the electrode have a direct impact on the capacitance of the device.

When a voltage is applied across the two electrodes, the positive voltages accumulate in the oxide coating, creating overlapping electric fields. This increases the capacitance of the device and allows it to store more energy. At the same time, the waxy properties of the oxide coating keep the electric-field charges from leaking away, providing more stability and accuracy.

In some designs, the capacitor is polarized, meaning that current flows in only one direction. This is because the positive electrode is formed from the oxide coating, causing it to possess a slightly higher voltage rating than the negative electrode. As such, special care needs to be taken when connecting polarization-sensitive devices.

Due to its high capacitance, low loss, and high stability, T495B225M035ZTE1K5 has become a popular choice for a variety of applications that require reliable and precise capacitance. Its wide range of voltage-rating options, combined with its size and form factor, make it an ideal choice for many applications.
