Tantalum Capacitors

M39003/01-2835H Application Field and Working Principle

Tantalum capacitors are one type of electrolytic capacitor that incorporate the use of the element tantalum as the anode. Currently, Tantalum capacitors are the most widely used capacitor in the electronics industry. The M39003/01-2835H capacitor is just one type of Tantalum capacitor. It offers high volumetric efficiency with a small footprint, low ESR, low leakage current, high ripple current ratings, and fast response time.Due to its small size, the M39003/01-2835H is often used in applications where board space is a concern, such as in cellular phones and notebook computers. It is also popular for its ability to start and stop functions quickly, making it suitable for applications that require quick response time, such as automotive electronics. In addition, its low ESR and high ripple current ratings make it a popular choice in power supplies and other applications that require large capacitance values.The working principle of a Tantalum capacitor is similar to that of a conventional aluminum electrolytic capacitor. It consists of an anode made of tantalum, a dielectric layer, and a cathode made of a conductive oxide film. The anode is the inner section of the capacitor and is connected to the negative terminal. The dielectric layer separates the inner sections from the outside. The cathode is the outer part of the capacitor and is connected to the positive terminal.When a voltage is applied across the terminals of the M39003/01-2835H, an electric field is generated across the dielectric layer which causes the tantalum anode to become polarized. This polarization causes electrons to flow from the cathode to the anode, forming a current. This current then creates an electric field and an electric charge which is stored between the two electrodes. This charge is the stored energy in the capacitor, and it allows current to flow through the device when needed.Due to its reliable performance and compact size, the M39003/01-2835H has become a popular choice for designers looking for a reliable low-profile capacitor. With its high volumetric efficiency, low ESR, low leakage current, and fast response time, the M39003/01-2835H is an ideal choice for use in a variety of applications such as consumer electronics, automotive electronics, and communication systems.
