Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, an electronic component that stores and releases electrical energy, and is typically made from a combination of materials including: tantalum, an oxide film, electrolyte, two electrodes and a lead. This combination of materials is not consistent across all types of tantalum capacitors and the exact composition of each type can vary, depending on manufacturer. The F931C686MNC, a type of Tantalum capacitor, is a polarized and axial-leaded, solid-chemical electrolytic capacitor which can offer low-resistive characteristics, high-rated voltage, low ESR and high capacitance. Its axial-lead, solid-chemical and case construction features make it optimal for use in high frequency switching power supply, RF frequency converting and signal coupling applications.

F931C686MNC Application Field

The F931C686MNC offers a wide range of applications relating to signal coupling, high frequency switching power supply, and RF frequency converting. Its sub-family label is MFD for single contact type and MDD for dual contact type. It has a rated voltage of 6.3V DC and its capacitance range is between 0.33 μF and 1500 μF with a rated capacitance tolerance of ±10%. It is able to provide high frequency and low ESR characteristics, as well as a low resistive capacitance rating. Its axial-lead and solid-chemical construction makes it well-suited for a variety of applications.

These features provide superior performance capabilities in applications such as automobiles, industrial equipment, power supplies, and precision audio instruments. In the automotive industry, the F931C686MNC is used to reduce electrical noise and improve power stability, while in industrial products it is used to increase switching speed, reduce power consumption and provide more efficient operation. Likewise, the F931C686MNC is used in power supplies to decrease heat generation, reduce the system size and increase overall efficiency. The F931C686MNC\'s superior performance capabilities also make it ideal for precision audio instruments as it ensures time accuracy and decreases distortion.

F931C686MNC Working Principle

The F931C686MNC is a type of polarized and axial-leaded, solid-chemical electrolytic capacitor, composed of two electrodes and conductive electrolyte, as well as a lead. Unlike other types of electrolytic capacitors, the two electrodes are not connected directly but rather separated by an insulating layer known as an oxide film. The F931C686MNC\'s operating principle is quite simple yet effective. Electricity flows from the positive side of the capacitor – the anode – to the negative side – the cathode – through the electrolyte, the oxide film, and the lead. In this way, the electrical charge accumulates on the opposite sides of the capacitor from one cycle to the next, until it reaches a certain level.

The F931C686MNC\'s capacitance value is determined by its anode and cathode area, thickness of the oxide film, electrolyte volume and lead type. It is important to note that the F931C686MNC is a polarized capacitor, meaning that the anode side of the capacitor is connected to the positive terminal of the power source, while the cathode side of the capacitor is connected to the negative terminal of the power source. This is necessary to ensure optimal capacitor performance.
