Tantalum capacitors are a type of electronic component capacitor which usually consists of two electrodes, permittivity electrolyte, and a conductive oxide of the tantalum metal in an enclosed package. The F930J686MAAAJ6 is a tantalum electrolytic capacitor, commonly referred to as a ‘tant cap’. This part is an axial leaded, surface mountable and polarised capacitor. It has a capacitance of 0.68uF, a dielectric type of Tantalum and a voltage rating of 16V.

The main application areas of the F930J686MAAAJ6 are in filter applications and decoupling applications. Tantalum capacitors are used in various types of circuits due to their low equivalent series resistance (ESR) and small physical size. As such, they are ideal for use in high-density circuit applications such as mobile phones, personal digital assistants (PDAs), laptop computers and other producst that require miniaturisation.

The F930J686MAAAJ6 is also used in applications with higher current requirements and higher voltage ratings than standard capacitor components. Such applications include voltage regulator circuits, frequency converters, medical electronics and battery operated equipment. In addition, it is also used as an offset capacitor in certain circuit designs.

The working principle of the F930J686MAAAJ6 tantalum electrolytic capacitor is based on electrolysis reactions. An internal oxidization reaction occurs between electrolyte and the tantalum anode, which forms the capacitance of the capacitor. The current through the capacitor is due to the flow of electrons in the electrolyte and the anode. The electrons are attracted to the positive end of the capacitor, which builds up an electrostatic charge on the electrodes.

Once the desired voltage is reached, the electrolyte between the anode and the cathode forms a barrier, preventing further current flow. This barrier that is created is the dielectric layer of the capacitor. A positive charge builds up on the anode, while a negative charge builds up on the cathode side. This creates the voltage difference between the two electrodes, leading to the formation of a capacitive device.

The F930J686MAAAJ6 has a tolerance of ±10%, a temperature coefficient of +2250ppm/°C, an operating temperature range of -55°C to +105°C and a ripple current of 1A. The capacitor offers excellent capacitance and low ESR values, making it ideal for use in high-efficiency filters, decoupling and DC-DC converters. In addition, it also provides an improved ripple current carrying capability and excellent stability under varying conditions.
