Tantalum Capacitors

Tantalum capacitors, or tantalum electrolytic capacitors, are a type of electrolytic capacitor. They are capacitors which use tantalum as the anode, with an oxide layer as the insulative dielectric layer and an electrolytic solution as the cathode. They are much smaller than traditional aluminum electrolytic capacitors, and are more expensive. Additionally, they are known for greater efficiency, reliability, and higher capacitance.

F920E336MPA Application Field and Working Principle

The F920E336MPA is a type of tantalum capacitor made by Johanson Manufacturing Corporation. It is a low-profile, high-performance, high-reliability hermetically sealed tantalum electrolytic capacitor. It is primarily used in communications, navigation, radar, and other military-grade applications. In addition, it can be used in a variety of commercial applications, such as power supplies, data processing, and signal conditioning.

The F920E336MPA utilizes a special manufacturing process to manufacture the tantalum anode, which is a key feature of this capacitors efficiency and reliability. To produce the anode, a tantalum cathode powder is encapsulated in a solid polymer. This process is called tantallization and results in the anode becoming chemically inert with respect to the electrolyte. This inert anode is then connected to the connections of the capacitor, forming a highly stable electrical circuit.

When electricity is applied to the F920E336MPA, electrons are attracted to the anode and move through the oxide dielectric layer and into the electrolyte, where the electron flow is counterbalanced by cations. This creates an electrical charge that can be used to store energy. Since the Tantallum anode is chemically inert, the electrical charge remains stable and the capacitor can maintain its capacitance.

In addition, the F920E336MPA has a self-healing characteristic that is an important factor for any capacitors intended use in critical applications. The self-healing characteristic of the F920E336MPA is due to the fact that any excessive stress on the dielectric layer caused by an electrical spike will cause the oxide layer to become conductive and short the capacitor. The current will redistribute itself along the surface of the oxides layer until it is dissipated and the capacitor returns to its original capacitance and voltage ratings.

Overall, the F920E336MPA is a highly reliable and efficient type of tantalum capacitor that is well-suited for a variety of military and commercial applications. Its precise manufacturing process ensures its high performance and longevity, making it a perfect choice for applications that require a high level of reliability and efficiency.
