F920E226MAA Application Field and Working Principle
Tantalum capacitors are an important type of capacitors which are widely used in electronics circuits. They are made from a mixture of tantalite ore and aluminum oxide, while the tantalum anode is sealed in an electrolyte. The anode of the tantalum capacitor is made from the same type of tantalum metal as is used in conventional electrolytic capacitors and the dielectric is made from an oxide of the Tantalum.
F920E226MAA is a popular model of tantalum capacitor and is used in a wide range of applications, including military, consumer and industrial electronics. This type of capacitor is manufactured using a coated anode that is formed from rectangular and/ or round tantalum sheets, which are then sealed with an electrically conductive epoxy for added protection. Its dielectric is an aluminum oxide, which gives the F920E226MAA a high working temperature and a wide operating temperature range.
The working principle of F920E226MAA is based on the principle of charge storage. When the capacitor is connected to a DC voltage, charges move onto the anode of the capacitor and accumulate on its dielectric layer. Achieving a balanced charge between the anode and the dielectric layer results in an electrical field between the two which stores the electrical energy of the capacitor. When a current is passed through the capacitor, this electric field is disrupted until the charge is fully discharged.
In order to protect the anode of the F920E226MAA from damage due to excessive voltage, an electrical stress protection circuit is provided. This circuit contributes to the enhanced voltage resistance of the capacitor. In addition, it also provides increased thermal protection to the capacitor by compensating for any variations in temperature and voltage.
When the F920E226MAA is used in a variety of application fields, its long life characteristics are essential for that application. Its properties of high reliability and low ESR make it particularly suited for use in harsh environments such as energy, automotive, and military applications, as well as in consumer electronics. It is also used in power supplies, as its low ESR reduces power losses.
The F920E226MAA tantalum capacitor is a reliable and robust storage component that is capable of providing excellent performance in a variety of applications. Its long life characteristics and robust design make it especially suited for use in harsh environments. Its low ESR and high reliability also make it an ideal choice for power supply applications.
