Tantalum Capacitors: M39003/01-3131H Application Field and Working Principle

Tantalum capacitors, also known as Ta-Caps, are a type of capacitors made from the element Tantalum. They are mostly used in industrial and military applications as they are widely known for their reliability, high capacitance values, and long life. These capacitors are popular for their low-ESAn, which is the equivalent series resistance of the capacitor. In addition to this, they are also known for their high temperature tolerance and high frequency characteristics.The M39003/01 is a series of metalized anodic tantalum capacitors. These capacitors have an anodic tantalum core that has been metalized to increase the surface area of the capacitor by providing an additional conductive plate. This improves the effectiveness of the capacitor by increasing its capacitance. Moreover, they also feature low ESR and long service life.The 3131H M39003/01 is a radial leaded tantalum capacitor specifically designed for high-temperature and high reliability applications. It has a voltage rating of 100VDC and a capacitance range from 10 to 100µF. This capacitor is often used in communications, military, and automotive environments.The M39003/01-3131H is an electro-static discharge (ESD) protected type of tantalum capacitor. It is designed to withstand high ESD levels of up to 8kV without performance degradation or catastrophic failure. It is also suitable for use in high-vibration, space-limited, low-temperature environments.The working principle of the M39003/01-3131H is based on the principles of static or constant capacitance. This means that it uses electrostatic fields when storing electrical energy between two conducting surfaces. The capacitor consists of two conducting plates separated by a dielectric material or layers. When a voltage is applied, electrons are attracted to one plate and repelled from the other plate, creating a stored electric charge. This electric charge is then discharged when the voltage is removed.Tantalum capacitors like the M39003/01-3131H are often used in a variety of industries and applications, ranging from automotive, telecommunications, computer, and medical applications. Their high-temperature and ESD tolerance make them suitable for use in environments where these conditions are common. Furthermore, their long service life and reliability make them an ideal choice for long-term installations.
