Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of capacitor that uses tantalum powder as its anode to form a written oxide layer. These tantalum capacitors are used in almost all electronic equipment because of their small size and high cost performance. THJD686M016RJN is one of the typical tantalum capacitor of Shenmao, which has a lot of applications and working principles.

Applications:

The THJD686M016RJN can be used for a wide variety of applications such as filters, clock oscillators, power supplies, voltage regulators, and more. Due to its low equivalent series resistance (ESR), it is suitable for high-frequency applications and provide high capacitance. The capacitor features a small size, allowing designers to easily make space within their set designs.

With a capacitance value of 6.8 μF, the THJD686M016RJN has a rated voltage of 16 Vcd, which means it can be used in applications requiring up to 16 volts. The total capacitance tolerance is ±20%. The THJD686M016RJN is also perfect for decoupling in mobile phones, since its small size allows it to fit into tight places. This capacitor also has excellent stability under temperature, with a temperature coefficient of ±30ppm/°C.

Working Principle:

The working principle of a tantalum capacitor is based on using tantalum metal as the anode. The tantalum is first oxidized, forming a solid thin film of electrically insulating material on its surface. This insulating layer, also known as the dielectric, increases the capacitor\'s capacitance and prevents current leakage. The second electrode, or cathode, is generally made of aluminum which is applied over the dielectric.

The resultant combination acts as a capacitor, as the capacitance depends on the layer of the dielectric and the distance between the two electrodes. The dielectric relies on the thickness of the oxide layer and the capacitance depends on the surface area between the two electrodes. As current flows between the anode and cathode, an electric field is created that causes the oxide layer to thin out and ultimately break down. That is why it is important to choose the right rated voltage for the desired application.

Conclusion:

The THJD686M016RJN is a high-quality tantalum capacitor from Shenmao. It is designed to handle rated voltage up to 16 Vcd and has an excellent temperature coefficient. This tantalum capacitor is ideal for filter applications, clock oscillators, and decoupling in mobile phones and other electronic equipment, due to its small size and low equivalent series resistance (ESR). With its robust design and reliable performance, the THJD686M016RJN offers a great choice for designers when working on high-frequency applications.
