Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor, which are components that store electrical energy. These capacitors have a higher capacity than the traditional aluminum electrolytic capacitors, they have long lifecycle expectancy, and they are highly stable, reliable, and cost-efficient, making them ideal for a wide range of applications.

T95Y686K004EZSL Application Field and Working Principle

The T95Y686K004EZSL from Vishay is a high reliability, long life, low ESR, and high temperature tantalum capacitor. It is an extended voltage polarized device with a high temperature rating and the ability to handle surge currents. This device is used for applications where very high ripple currents and/or high temperatures are encountered. It is very suitable for DC/DC converters and in automotive DC/AC inverters.

The T95Y686K004EZSL operates according to the electrolytic capacitor principle. This is where two conductive surfaces are separated by an electrically conductive material, usually a dielectric material such as plastic, ceramic, or paper. An electric charge is applied to the two conductive surfaces causing a dielectric polarization that results in a capacitance value. The voltage applied to the capacitor also affects the capacitance value, so higher voltage will lead to increased capacitance.

The T95Y686K004EZSL is a high-temperature, high ripple current device. Its capacitance is stable over a wide temperature range, up to 125°C. This stability is achieved by its special SO-23 construction, which is a hybrid of an axial component and a surface-mounted component. This unique design allows the device to dissipate heat at a much higher rate than conventional electrolytic capacitors.

The T95Y686K004EZSL is a low-ESR device, which means it has a lower internal resistance than other capacitors. This low ESR reduces ripple current to an acceptable level, making it ideal for high-frequency switching power supplies. The low ESR also helps reduce power losses and is especially helpful when the capacitor is subject to large amounts of electrical current.

For applications requiring robust construction and long life, the T95Y686K004EZSL is an excellent choice. The device has a long life expectancy, up to 3000 hours at 125°C, with a leakage current down to 1µA. It is highly stable, reliable, and cost-efficient, making it ideal for a wide range of applications.
