Tantalum Capacitors

The M39006/22-0642 is an encapsulated, surface-mounted, radial-leaded, Tantalum capacitor, which is a type of electrolytic capacitor. It is made up of two electrodes separated by a dielectric layer, typically a solid tantalum oxide. This capacitor type is characterized by its small size, extremely low equivalent series resistance (ESR), and high capacitance to weight ratio. The typical application of M39006/22-0642 capacitors is for purchasing or storing electrical energy in the form of an electric charge.

Application Field of M39006/22-0642

M39006/22-0642 capacitors have a wide range of uses in both industrial and consumer electronics. These capacitors are frequently used in power management and power conversion for products such as automated guided vehicles (AGVs), small motor drives, medical equipment, LCD and LED television sets, networking equipment, DC-DC converters, low-power digital systems, memory modules, microprocessors, and application specific integrated circuits (ASICs). In addition, these capacitors are often used in energy-harvesting devices, automotive electronics, and defence and aerospace. Furthermore, the M39006/22-0642 components offer superior capacitance and noise performance at an extremely low ESR, and are thus ideally suited for use in critical applications, such as control-circuit resonance and power amps.

Working Principle of M39006/22-0642

M39006/22-0642 Tantalum capacitors employ a chemical reaction between two materials, the dielectric tantalum and the electrolyte of the capacitor, to form a polarized dielectric layer. The electrolyte is usually an organic solvent, such as propylene carbonate (PC). This reaction occurs between two electrodes, the anode and the cathode. The anode structure is typically rolled or pressed tantalum powder *or today, pellets of sintered tantalum powder* placed in a case. The cathode structure is a thin layer of conducting material, such as a coil, usually made of nickel, which is deposited onto the tantalum anode. During the capacitor formation process, a voltage is applied to the anode and the electrolyte, which causes the tantalum anode to react with the electrolyte. This initiates a chemical reaction within the capacitor, resulting in an electrical charge stored in the capacitor between the anode and the cathode.

The main advantage of the M39006/22-0642 is its very low ESR. This characteristic makes this capacitor type particularly suitable for use in devices that require high current and low voltage. Another benefit of the M39006/22-0642 is that it offers exceptionally high capacitance-to-size ratio. This makes it one of the most compact and reliable capacitors on the market today.

The M39006/22-0642 tantalum capacitors have excellent performance characteristics and are, consequently, widely used in various consumer and industrial applications due to their superior performance. Their small size, high capacitance, low ESR, and superior thermal performance make the components an excellent choice for use in power supplies, medical equipment, machine controls, and other devices and systems.
