Tantalum capacitors are a type of electrolytic capacitor that use a tantalum metal as the anode, covered with a non-conductive oxide layer to provide the capacitance value. TH3B685M016F1800 is one of such tantalum capacitors, which has a C rated capacitance value of 6.8µF and maximum working voltage of 16V.

Tantalum capacitors have a variety of uses in most electronic designs. They are generally used in power supply designs where a large capacitor requirement exists. They are ideal for both analog and digital applications such as radio, audio, video, instrumentation, and industrial control as well as hardware and software development.

TH3B685M016F1800 is mainly used in applications where low-ESR (Equivalent Series Resistance) is needed and the circuit needs long-term reliable performance with low leakage current. It has high ripple current ratings and good temperature range, making it suitable for communication devices, PC boards, automotive audio, and high-reliability military applications.

The working principle of TH3B685M016F1800 is similar to other electrolytic capacitors. An anode made of tantalum is used in TH3B685M016F1800, which is then covered with an oxide layer to provide electrical insulation and to form a dielectric. The dielectric layer has the property to trap electric charges and can store potential energy in the form of an electric field. This oxide layer also acts as a barrier between the anode and the cathode, thus providing a high breakdown voltage and stability. A cathode formed from aluminum foil is then connected on the other side of the dielectric layer. This causes an electrical current to flow through the tantalum anode and the oxide dielectric layer to the aluminum cathode. This current flow is responsible for storing the electric energy in the form of electric field between the anode and the cathode.

The charging time of the capacitor is determined by the RC time constant. During the charging cycle, an electric current passes through the capacitor and charges the capacitor to its peak value. This peak value remains more or less constant until the capacitor is completely discharged. The capacitance and voltage rating of TH3B685M016F1800 is 6.8µF and 16V respectively. This means the peak voltage of the capacitor will be 16V. During the discharging cycle, the capacitor will gradually discharge its electric charges until it reaches its minimum value.

TH3B685M016F1800 is a versatile tantalum capacitor that is suitable for many different applications. It offers good performance with low ESR and high ripple current ratings, as well as good temperature range. It is ideal for a wide range of communication, PC boards, automotive audio, and high-reliability military applications. The working principle of the capacitor is based on the principle of trapping and storing electric charges in a dielectric layer which is then discharged gradually when electric current is passed across the capacitor.
