Tantalum Capacitors

Tantalum capacitors are a type of capacitor specifically designed for a wide range of applications and have become an increasingly important component in many fields of electronic engineering, from consumer electronics to industrial automation. In this article, we will discuss the application field and working principle of a 199D186X9020D2V1E3 tantalum capacitor.Tantalum capacitors are very popular due to their ability to withstand high voltage, their small size and their good performance at high temperatures. The 199D186X9020D2V1E3 capacitor is a low impedance variant, designed for applications that require extreme reliability.These capacitors can be used in various applications where high voltage, high temperature and/or high frequency are required. Applications include power supplies, switch mode power supplies, and DC-DC converters. The 199D186X9020D2V1E3 is also used in audio and video equipment, telecommunications, medical, avionics, and automotive industries.Working principle of a tantalum capacitor is based on capacitance, which is the ability of a material to store charge. The capacitance of a capacitor depends on the amount of dielectric material between the two conducting electrodes, and how close they are to each other. The 199D186X9020D2V1E3 capacitor provides a low-impedance connection and has a capacitance of 1.86uF at a rated working voltage of 20V.The fundamental element of a tantalum capacitor is called the "anode". It is composed of a tantalum powder which conducts electric current and is held in place by a polymer matrix. The cathode is made of an electrically conductive material usually a metal and is connected to the anode.When the capacitor is charged, the anode builds up an electronic surface charge which repels electrons from the cathode and causes current to flow in a circuit. When the capacitor is discharged, the cathode attracts electrons back from the anode, causing current to flow in a reverse direction. The total charge stored in a capacitor is known as capacitance, and is measured in farads (F).The 199D186X9020D2V1E3 capacitor features low-ESR (equivalent series resistance) and very low stray inductance, making it very suitable for use in high-frequency applications. It has an ESR (or equivalent series resistance) of 0.33 Ohm, which is very low for this type of capacitor.Tantalum capacitors are increasingly popular due to their high reliability, small size and good performance at high temperatures. The 199D186X9020D2V1E3 capacitor is a suitable choice for applications that require extreme reliability in difficult environments, including high voltage, high temperature and/or high frequency.
