Tantalum capacitors consist of tantalum powder pressed into a pellet shape and then etched through an anode pattern on the surface. In its original form, tantalum powder exhibits very high efficacy of energy storage, due to its highly porous nature. Through the etching process, the tantalum powder is altered, allowing for solid-state reactions to occur, which hold the stored energy better.

The capacitor model M550B757M075AT is a particularly popular choice among tantalum-polymer capacitors. It is manufactured with solid polymer electrolyte, giving it upgraded mechanical robustness and temperature performance over its tantalum-electrolyte analogs. This type of capacitor is used in the production of electronic supplier parts, such as voltage regulators, electrolysis filters, and clocks.

The M550B757M075AT model is what is referred to as an axial-lead capacitor, meaning it has two leads at opposing ends for connection. It is a low-profile type capacitor that is low on power consumption, making it well-suited for portable applications, such as laptops or tablets. It exhibits a wide operating temperature range from -55°C to +125°C and is designed to have high vibration and shock resistance.

Working Principle

The working principle of the M550B757M075AT is similar to all including tantalum-polymer capacitors. It consists of two plates, separated by a insulating layer. When a voltage is applied to the capacitor, the positive charges attract to the negative plate, and the negative charges attract to the positive plate. By controlling the surface areas and distances between the two plates, it is possible to dictate the amount of charge stored by the capacitor.

The M550B757M075AT has a solid-polymer construction, which enables the unique use of a single-layer electrode. The single electrode layer has superior volumetric efficiency, allowing for storage capacities up to half the size of traditional capacitor technology. This enables the capacitor to be smaller in size, while still retaining the same charge storage capability.

Conclusion

In conclusion, the M550B757M075AT is a low-profile, low power-consuming capacitor, specifically designed with solid-polymer construction. It has two opposing leads, and is especially well-suited for portable applications, due to its wide operating temperature range and vibration/shock-resistance. It is a popular choice among tantalum-polymer capacitors, as it exhibits high volumetric efficiency and can store the same charge capacitance as larger capacitors.
