Tantalum Capacitors

Tantalum capacitors, sometimes referred to as "tantalum electrolytic capacitors" or "tantalum electrolytic capacitors," are electronic components used for storing electrical energy in circuits. They are made from a material called tantalum (which contains tantalum pentoxide dissolved in an electrolyte), and feature two terminals – the anode and the cathode – which extend from the edges of a tantalum electrolytic capacitor’s body. The anode receives electrical current, while the cathode discharges it.

T95R476K020LZSL, commonly referred to as a "wet" tantalum capacitor, is a type of tantalum capacitor designed for operation in the low temperature range of -55°C to 150°C. It is composed of a tantalum pellet anode and a coating of manganese dioxide embedded in a solid epoxy body. The anode and cathode materials are selected for optimal performance in high-temperature environments, and the unit\'s low ESR (Equivalent Series Resistance) values allow for high-reliability operation.

The T95R476K020LZSL application field includes avionics, aerospace, oil and gas instrumentation, and military electronics. Additionally, it can be used for circuit protection, decoupling, and power supplies in high-temperature electronics. This type of capacitor is highly reliable due to its high temperature capabilities.

The working principle of the T95R476K020LZSL is based on the electrical double-layer that builds up at the electrodes of an electrolytic capacitor. When an electrical potential is applied across the two terminals of the capacitor, ions in the electrolyte along with positive charges from the anode are attracted to the negative end of the electric field, i.e. the cathode. This electric double-layer builds up a charge at the anode and cathode, allowing the capacitor to store electrical energy.

The high temperature capabilities of the T95R476K020LZSL make it an ideal choice for applications in which higher temperatures are expected. This type of capacitor also has a low equivalent series resistance, which leads to better reliability and higher power densities. Additionally, the encapsulating epoxy resin material also ensures a longer life cycle in high-temperature applications.

In summary, the T95R476K020LZSL is a type of tantalum capacitor that is designed for operation in the low temperature range of -55°C to 150°C. It is a highly reliable and robust component for applications in which high temperatures are expected. The working principle of this capacitor is based on the electrical double-layer that builds up at the electrodes of the electrolytic capacitor.
