Tantalum Capacitors
Tantalum capacitors are electrochemical capacitors that use tantalum metal for both electrodes and dielectric, and are one of the most common types of capacitors. They are widely used in electronics due to their small size and high capacity, and are available in both polarized and non-polarized packages.
M39003/03-0343/TR Application Field and Working Principle
M39003/03-0343/TR are a type of tantalum capacitors. This type of capacitor is used mainly for filtering and decoupling, as well as for storing charge and maintaining a steady voltage. The M39003/03-0343/TR is a type of axial electrolytic tantalum capacitor. It has two leads (positive and negative) that are connected to the electrodes, with the electrolyte (solid manganese dioxide) filling the gap in between. The positive lead is generally marked with a “+” sign, and the negative lead with a “-” sign. The capacitance of the M39003/03-0343/TR is 180 µF, and it has a voltage rating of 6.3 VDC.
The operation of the capacitor is based on the principle of electrical double layer capacitance, which occurs when two closely spaced layers of charge (electrons and ions) form opposite electrical charges in a dielectric material. This is due to electrical attractions and repulsions between the charges of different type. The dielectric material between the two conducting surfaces, one positive and one negative, creates an electric field. When a voltage is applied across the two conducting surfaces, charge starts to collect on the surface of the dielectric, resulting in the buildup of opposite electric fields that make up the capacitance. This is the basic principle behind the operation of all tantalum capacitors.
Tantalum capacitors are used in a wide variety of applications, including computers, smartphones, automotive systems, industrial equipment, and audio/video systems. Some of their key advantages include their high capacitance, low leakage, high reliability, and low cost. Furthermore, these capacitors are also known for their stability over temperature, making them ideal for use in temperature sensitive applications.
In conclusion, the M39003/03-0343/TR is a type of tantalum capacitor. This type of capacitor is used mainly for filtering and decoupling, storing charge, and maintaining a steady voltage. Its capacitance is 180 µF and it has a voltage rating of 6.3 VDC. These capacitors have a wide range of applications in electronics due to their small size and high capacity, as well as their stability over temperature.
