Tantalum capacitors are widely used in diverse fields and electronics applications, and serve many purposes. The T86D157K004ESSS series of tantalum capacitors from Vishay Semiconductor are no exception. These highly reliable, low-ESR capacitors boast excellent long-term stability and excellent high-frequency performance. They offer a wide range of voltage and capacitance values as well as several mounting options. This article will discuss the application field of the T86D157K004ESSS series as well as its working principle.

This series of capacitors has been designed for use in high-temperature and high voltage applications. Due to their low equivalent series resistance (ESR) and low leakage current, these capacitors are suitable for use in extremely high temperature environments up to 105C. Their wide range of capacitance values, from 7.5μF to 390μF, also makes them suitable for use in a variety of applications. With their high surge current rating, these capacitors are also ideal for high-reliability applications such as automotive and aerospace. Their stability and reliability make them a great choice for use in these demanding fields.

The T86D157K004ESSS series is constructed with a solid tantalum housing and an MnO2 electrolyte that provides excellent first-line protection from excess voltage, over-temperature, and over-current. Its polarization layer adjusts the dielectric thickness and enables a variety of voltage rating with minimal change in capacitance value. This robust construction ensures excellent electrical and thermal endurance and makes the capacitors suitable for use in high-heat applications.

At the heart of the T86D157K004ESSS series is its working principle. Like any other capacitor, these capacitors store electrical energy in an electrostatic field. This energy is stored by the capacitor’s two terminals, which are separated by a dielectric material. The amount of electrical energy that can be stored in the capacitor is determined by the thickness of the dielectric, which is related to the capacitance of the device. In the case of a tantalum capacitor, the dielectric is formed by a layer of tantalum oxide. The higher the capacitance, the greater the voltage that can be stored in the capacitor.

In the T86D157K004ESSS series, the dielectric is polished with a voltage-dependent material, allowing for a wide range of voltage ratings with minimal change in capacitance values. Additionally, the polishing process helps reduce the resistive losses and current leakage, resulting in an energy-efficient capacitor with excellent long-term stability. Furthermore, the MnO2 electrolyte helps to provide excellent first-line protection from excess voltage, over-temperature, and over-current.

The T86D157K004ESSS series from Vishay Semiconductor is designed for use in high-temperature and high voltage applications. Thanks to its robust construction, low equivalent series resistance (ESR), and low leakage current, these capacitors offer excellent long-term stability and excellent high-frequency performance. With its wide range of capacitance values, high surge current rating, and several mounting options, the T86D157K004ESSS is a great choice for use in demanding fields such as automotive and aerospace.
