Introduction to Tantalum Capacitors

Tantalum capacitors are electrical components composed of a tantalum anode, tantalum oxide dielectric, tantalum cathode and internal electrolyte. They are low profile, small size and high temperature-resistant capacitors due to the nature of their construction. Furthermore, they provide stable capacitance over wide temperature ranges and provide excellent frequency characteristics making them ideal for use in a variety of audio and communication applications. T356C225M035AT capacitor is a surface mount tantalum capacitor, specifically designed to deliver dependable performance in high temperature, high vibration, and high frequency applications. This capacitor type is characterized by two components: an electrolytic tantalum anode and a solid tantalum core. The anode of the capacitor is composed of a large, flat metallic plate held in a metal case. The small core contains an electrolyte, which creates a electrical connection between the anode and the cathode.

Application Fields of T356C225M035AT

T356C225M035AT capacitors are widely used in a variety of industrial applications due to their superior performance characteristics. Examples of these applications include electronic filters, grounding planes, and for bypass capacitance in consumer electronics. The small size and low profile of these capacitors also make them an ideal choice for use in miniaturized and portablesystems, where space is limited.Additionally, these capacitors can be used in high frequency, high efficiency power supplies and amplifiers. Their robust dielectric and long shelf air life make them suitable for longterm operation and extended life cycle applications. Their dependable performance and small size make them ideal for use in high power and automotive systems.

Working Principle of T356C225M035AT

The working principle of a T356C225M035AT capacitor is relatively simple. It features an electrolytic tantalum anode and a solid tantalum core, which together create an electrochemical reaction. When a potential is applied to the anode, electrons are drawn to the anode from the core, which forms a dielectric layer between the two components. This dielectric layer has the ability to store electrical energy, known as capacitance, which is measured in Farads, and is used to store electrical energy and then discharge it when requested. The anode is usually made up of a sintered or pitted disc the same size as the core, and it has a special electrical property that is especially useful in capacitor construction; its ability to attract, hold and control charge. This charge is comprised of free electrons that naturally move around, and when they are attracted to the anode, they form an electrostatic field between the anode and the dielectric. This electrostatic field acts as an electrical storage device, meaning that any voltage applied to the terminals will cause the anode to discharge an electric current, if required. The dielectric material, which is usually made up of tantalum oxide and molecular adsorption layer, works to insulate the electrons from the anode, which allows an electric current to flow without damaging the capacitor when the voltage is applied. This electric current then goes to the capacitor’s cathode, which is an electrically conductive material, and is then released into the circuit. The capacitor is then ready to receive and store more energy when the voltage is applied again. T356C225M035AT capacitors are popularly used in audio and communication applications due to their relatively small size and low profile, as well as their stable capacitance over wide temperature ranges and excellent frequency characteristics. They are also commonly used in industrial applications such as high frequency, high efficiency power supplies and amplifiers, as well as automotive systems. The capacitor works by storing electrical energy in an electrostatic field, between its anode and dielectric, and then releasing the stored current when a voltage is applied. This process is then repeated to charge the capacitor for another cycle of usage.
