T95R187M016ESAS

Introduction

Tantalum capacitors (or Ta-Caps) are electrochemical capacitors that use a tantalumrod as their anode and an oxide dielectric as their dielectric with a solid manganesedioxide electrolyte. They are used in a wide variety of applications, such as high-frequency electronics, military electronics, general aerospace, and medical electronics. The T95R187M016ESAS (T95R187) is a Tantalum capacitor manufactured by AVX Corporation.

Application Field

Tantalum capacitors are mainly used for power electronics, because of their high capacitance-to-volume ratio and extremely low equivalent series resistance (ESR). The T95R187 is one of the most popular options for power electronics applications. This capacitor is a miniature SMD type, with a maximum leakage current of 0.4 mA at 1.0V DC, capacitance of 2.2µF, low equivalent series resistance (ESR) of 10Ω, and a rated voltage of 6.3V.

The T95R187 is used in a variety of applications, including high-frequency switching, self-powered and voltage-controlled oscillators, and digital audio systems. It is also used in LED lighting, high-end applications, automotive electronics, and power line filters. The flexibility of this capacitor makes it ideal for a wide range of applications. It is suitable for use in high-speed signal lines, such as a graphics card or a computer bus.

Working Principle

The working principle of a Tantalum capacitor is based on Faraday’s Law of electrical induction. As an electric field is applied between two plates, one of the plates accumulates electrons while the other plate expels them. The charge accumulated on one plate forms an electric field between the two, and this electric field creates an electric current. When a current passes through a capacitor, an electric field is created within it, which in turn generates a voltage.

This current flows through the anode and cathode of the capacitor and creates a charge imbalance. The anode and cathode of a Tantalum capacitor are formed by the tantalum rod and the oxide dielectric layer. The electric current also passes through the manganese dioxide electrolyte, which acts as a bridge between the anode and cathode.

As the current passes through the capacitor, it creates an electric field, which in turn creates an electric current passing through the manganese dioxide electrolyte. This current causes the electrolyte to oxidize, increasing the dielectric strength of the capacitor. As the dielectric strength increases, the capacitance of the capacitor increases as well.

The capacitance of a Tantalum capacitor is dependent on its size, capacitance and the operating voltage. The T95R187 has a maximum capacitance of 2.2µF and a rated voltage of 6.3V, and is therefore suitable for use in high-speed signal lines, such as a graphics card or a computer bus.
