Tantalum Capacitors - TAJY686K016RNJ application field and working principle

Tantalum capacitors are special kind of aluminum-based capacitors. These capacitors are manufactured with titanium electrolytic materials. The most common use of tantalum capacitors is in power supply filter applications, due to their ability to handle large current and high voltage. They are also used in many electronic devices, such as computers, cell phones, and even medical equipment, due to their reliability, low leakage current, low cost, and simplicity. In general, a tantalum capacitor consists of two sections, the anode and the cathode, placed in a sealed unit. The anode is basically a metal plate with a conductive surface. The cathode consists of a tantalum oxide dielectric, which is surrounded by tantalum powder. An electrolyte solution is filled in the unit which serves as a solvent. A polarized cathode is connected to the anode, forming the capacitor. The TAJY686K016RNJ is a type of high-voltage tantalum capacitor, with a maximum working voltage of 1.7KV. It is an axial lead, axial capacitor, with a 22uF capacitance and 16V rated voltage. The application field of TAJY686K016RNJ is in power supply filter and pulse power filter, due to its ability to handle voltage and current surges at a very high rate. It is suitable for DC and pulsed power systems and can be used as a high-powered capacitor for large output and high reliability. The TAJY686K016RNJ is also ideal for DC-DC converters and motor-control applications.The working principle of a tantalum capacitor is based on the fact that capacitors primarily store energy in an electric field. In order to charge a capacitor, an electric voltage is applied across it. This causes a rearrangement of available electrons, resulting in an electric field in the capacitor’s dielectric material. Of course, the capacitor can discharge and transfer the stored energy into an external circuit. In the case of a TAJY686K016RNJ, the electric field is particularly strong due to its metal cathode construction which features two layers of tantalum oxide dielectric with a metal foil center electrode. As the capacitor is charged and discharged, the metal foil center electrode allows the electrons to move total flow, producing a consistent and reliable current. The TAJY686K016RNJ is a high quality, reliable capacitor, capable of withstanding high voltage and current surges. It is suitable for a wide range of DC and pulsed power applications, providing excellent capacitor performance and dependability.
