Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor primarily used in military and aerospace applications due to their low-inductance, low-profile body and their relatively high capacitance. The TH3C156M020C1000 is an example of a tantalum capacitor. The TH3C156M020C1000 has a capacitance of 1000 µF and a working voltage of 15.6V.

Application Field of TH3C156M020C1000

The TH3C156M020C1000 is typically used in mil-spec and avionics applications where its features make it an ideal choice. The small size, high capacitance, low profile, and low-inductance shape make it well suited for projects where size and capability are key objectives. It is especially suited for applications where vibration is a factor, due to its hermetically sealed metal package, which ensures stability and consistency in operation. Additionally, the dip coating ensures that the capacitor is reliable over a wide temperature range. The TH3C156M020C1000 can also handle a wide range of temperatures, from -55°C to 85°C.

Working Principle of TH3C156M020C1000

The TH3C156M020C1000 can be recognized with the positive and negative terminals. The positive side is made of Tantalum pentoxide and the negative side is made of manganese dioxide. The Tantalum pentoxide and manganese dioxide react when current is passed through them, forming a film that acts as a dielectric between them. This dielectric layer is what stores the charges and facilitates flow of current when the capacitor is being discharged. As charge is stored, the dielectric layer builds up an electric field, which increases the dielectric strength of the capacitor. This process produces the capacitive effect, which is essential for storing and transmitting electrical energy.

The TH3C156M020C1000 also features high levels of thermal stability. This is because the capacitor is hermetically sealed in metal packaging. This helps to ensure consistent performance and reliability in applications where temperature may vary significantly. Additionally, the dip-coating process helps to protect the capacitor from moisture, ensuring reliable operation even in humid conditions. This feature makes the TH3C156M020C1000 an ideal choice for avionics and military applications.

Overall, the TH3C156M020C1000 is an ideal choice for applications where high capacitance, low inductance and robust packaging are needed. Its small size and high capacitance rating make it a suitable choice for miniature military and aerospace projects, while its hermetically sealed metal package and dip-coating process make it an ideal choice for applications where vibration and humidity may be present.
