Tantalum Capacitors

Tantalum capacitors are an essential type of capacitor technology that are used in various types of electrical applications. They have been around for decades with the latest versions capable of replacing traditional capacitors such as aluminum electrolytic capacitors due to their smaller size and rapid charging-discharging capabilities.

TR3E226M035C0275 is a tantalum capacitor that is designed for use in high and mid voltage applications such as AC/DC converters, motor SCR controls, audio electronics, power supplies, lighting drivers, and other related circuitry.

Application Field

Because of its small size, TR3E226M035C0275 is ideal for use in high-density circuit boards. Its robust construction and superior capacitor design give it excellent electrical characteristics and makes it suitable for use in different applications that require high temperature resistance and superior reliability. Additionally, its high ripple current rating and lower ESR makes it suitable for high frequency applications, where it can reduce power loss, thus increasing energy efficiency. It is also applicable in electronic sets and board-level components that require low-ESR and high capacitance.

Working Principle

Tantalum capacitors are electrolytic capacitors, and go through similar manufacturing processes as traditional aluminum electrolytic capacitors. They have a semiconductor oxide layer that forms between two electrodes on the surface of a tantalum pellet. This creates a capacitor with a capacitance range between 1 microfarad and several thousand farads and a voltage rating of 16 to several hundred volts.

The capacitance of the tantalum capacitor is determined by the surface area of the pellet, the oxide layer thickness, and the relative permittivity of the oxide. The oxide layer is formed through a process called anodization. This oxidation reaction reversibly forms the oxide layer and sets the capacitance of the tantalum capacitor.

When an AC signal is applied to the tantalum capacitor, the capacitor absorbs some of the energy as a result of its dielectric layer. This then produces a reactive component on the waveform which is added to the signal. The current flow of the tantalum capacitor is also very low, making it highly suitable for use in low-power applications.

Tantalum capacitors have a wide variety of uses, from signal filtering to energy storage. They are also very popular with hobbyists, particularly when it comes to constructing custom gaming PC rigs or building sound systems. Their reliability and high capacitance makes them incredibly versatile for many different applications.
