Tantalum capacitors are a type of capacitor that has a tantalum metal electrochemical component. They are capacitors with a greater capacity or voltage rating than those constructed by other materials such as paper, ceramic, mica, or electrochemical film.

T97H477M016EBA, a type of tantalum capacitor, has a fixed-value and through-hole design. It is developed to meet the needs of demanding computing and telecommunications applications. Not only is it compliant with the European RoHS (Restriction of Hazardous Substances) Directive (2002/95/EC), it is also Pb-Free (lead free).

The application field of T97H477M016EBA includes automotive industry, communications, industrial control, datacom, and alternative energy markets. Popular applications include power supplies, switching converters, signal processing, microprocessors, backplane systems, and voltage regulators. It is made available in case sizes like 0603, 0805, 1210, 1812, 2220, and 2925xx that makes it suitable for low-power, high-current applications.

T97H477M016EBA consists of two tantalum electrodes embedded in a chemically activated anode deposited on an insulating oxide layer. By applying a voltage to the device, the tantalum oxide layer at the anode will ionize lithium ions (positive ions) through its oxide layer. When these lithium ions reach the anode, a chemical reaction occurs, creating a double layer between the two electrodes. This double layer serves as a dielectric, allowing for the electrical charge retention or capacitance of the device.

The capacitance of T97H477M016EBA depends on the insulating oxide layer, which increases as the oxide layer increases in size. This means that when current is applied to the device, the oxide layer becomes thinner and the capacitance decreases. This is why the device has a fixed capacitance: it is designed to remain consistent across the entire range of voltages and is not affected by changes in temperature or other environmental factors.

T97H477M016EBA is also known for its high current density, low ESR (equivalent series resistance), and high ripple current capability. It also has a low equivalent series inductance (ESL) and has good surge response capability, making it suitable for switch-mode power supplies.

In summary, the T97H477M016EBA is a type of tantalum capacitor with a fixed-value and through-hole design. It is compliant with the European RoHS (Restriction of Hazardous Substances) Directive (2002/95/EC), and is Pb-Free (lead free). It is used in applications such as automotive, communications, industrial control, datacom, and alternative energy markets, and boasts high current density and low ESR (equivalent series resistance).
