Tantalum capacitors are a type of capacitor, which makes up a significant portion of passive electronic components. The F951C105MPAAQ2 is an especially popular subtype of tantalum capacitors, used in a wide range of applications and equipment. In this article, the application field and working principles of this component will be discussed in detail.

The F951C105MPAAQ2 is a commercially-available, surface-mount capacitor, measuring only 2 x 1.2 x 1.4mm in size. Because of its small size, it is suitable for use in very compact products, such as cell phones, computers, digital cameras, game consoles and other devices that require many capacitors to function but have limited space for them. Moreover, due to its excellent characteristics, such as a high insulation resistance, it is also often used in other applications, such as medical equipment, automotive electronics, motor controls, military electronics, GPS and telecommunications equipment.

At its core, the F951C105MPAAQ2 is a solid tantalum capacitor, a type of capacitor that uses an electrolyte as its dielectric material. This particular capacitor is built with a tantalum anode, an electrolyte and a silver cathode, also known as the counter electrode. During operation, the capacitor stores energy by forming an electric field that is circular between the anode and the cathode. This is achieved by having a voltage difference between the two electrodes, resulting in a current flow that is equal to the product of the current and the capacitance of the device.

The F951C105MPAAQ2 also has a temperature coefficient, which is the change in capacitance per degree Celsius. This property is especially important as it dictates how stable the capacitance of the device is when exposed to changes in temperature. Typically, the temperature coefficient of a solid tantalum capacitor is around -75 parts per million per degree Celsius (ppm/°C).

The F951C105MPAAQ2 is also highly efficient due to its low profile and small size. This makes it well-suited for applications that require minimal form factor, such as portable devices, where the size and weight of the component are of paramount importance. Additionally, its efficiency makes it more resistant to failure and its long service life is an additional benefit.

Finally, the F951C105MPAAQ2 is designed to meet the MIL-PRF-55681 parameter requirements. This specification is a military standard that covers the performance requirements of certain types of electronic components. Such components must meet certain criteria, including temperature ratings, minimum capacitance and temperature coefficient, insulation resistance, etc. This specification is targeted at components used in military applications, and it is voluntary for the component manufactures to meet its requirements. The F951C105MPAAQ2 has met all these requirements, indicating its excellent quality.

To summarize, the F951C105MPAAQ2 is a small, highly efficient solid tantalum capacitor, which is suitable for use in a wide range of applications, especially portable devices. It has excellent characteristics and a high temperature coefficient, as well as adhering to MIL-PRF-55681 specifications. The combination of these features make it well-suited for use in various electronic devices and applications.
