Tantalum Capacitors:M39003/03-3022/TR Application Field and Working Principle

Tantalum capacitors are common electronic components, which are widely used in the electronic circuit system for various reasons. It could be used to store energy, filter signals, smooth signals and change signals to alternating current. This article will provide an introduction to the application field and working principle of M39003/03-3022/TR specifically.

1. Application Field

M39003/03-3022/TR tantalum capacitors have versatile applications. It could be used in power supplies, amplifiers, military and commercial equipment, instrumentations and aerospace. They offer reliability and high performance for operation condition like temperature -55 to +125°C, voltage range from 2 to 20V and capacitance range of 1 to 10000uF. Besides conventinoal operation, they also have special sealed cases and hermetic sealing, which can bear extreme temperature like liquid helium cryogenic environment.

2. Working Principle

M39003/03-3022/TR is an electrolytic capacitor, which consists of an anode and cathode and has a conductive electrolyte solution between them. A tantalum oxide film is formed and covers the anode surface. The anode is typically an oxide metal film, like tantalum pentoxide. At the same time, a solid manganese dioxide forms the cathode.

When the capacitor is applied with voltage, an anodized film will cover the anode, which functions like an insulator. A positive charge is built up on the anode and a negative charge builds up on the cathode. This charge builds until the voltage of the two sides becames equal. This generates a capacitance from anodized film, or the dielectric, between the anode and the cathode. The value of the capacitance depends on the size of the anodized film.

M39003/03-3022/TR capacitors can generally handle high current, so they are often used in application that require high current. They are also commonly used as power supply filters, due to their large capacitance.

3. Benefits
