Tantalum Capacitors

Tantalum capacitors are an important type of low-profile, polarised, non-solid electrolytic capacitor with moderate voltage and high-capacitance values. They consist of electrodes separated by an electrolyte, usually a metallic oxide, making them similar to an electrolyte capacitor but with a larger capacitance. They are commonly used for AC applications, such as in coupling circuits and as electrical buffer. The 293D155X9020A2TE3 is a type of tantalum capacitor that is suitable for various application fields. It is a polarised electrolytic capacitor that has a moderate voltage rating of 8V with a capacitance value of 2.2µF. Its low profile and small size make it ideal for use in miniature PCB circuits and other microelectronic applications.The working principle of the 293D155X9020A2TE3 is based on the use of a form of electrolyte known as an oxide layer. This layer acts as a dielectric and shields the anode and cathode terminals from one another, allowing a charge to be stored between them. When the terminals are connected to an AC circuit, the stored charge is transferred from one terminal to the other and then back, resulting in a charge exchange.The capacitor has two plates, the anode and the cathode. The anode is a positive plate and consists of a high-purity tantalum pellet formed from a sintered powder, with an oxide layer deposited onto it. The cathode is a negative plate and generally consists of a manganese dioxide layer formed on a substrate of specially treated sheet steel. These two plates are assembled into a small plastic case, with two leads connected to the anode and cathode for attaching to the circuit.The main advantages of the 293D155X9020A2TE3 are its low profile, small size, and high-capacitance value. It is also very reliable, with a shelf-life of up to 10 years, and is resistant to vibration and shock, making it ideal for use in applications where reliability is essential.The 293D155X9020A2TE3 is suitable for a range of applications, including filtering low-frequency noise, smoothing the output from audio amplifiers, and providing decoupling in computer systems. It is also commonly used in circuits where a large amount of capacitance is required in a small amount of space, as with mobile devices and small electronic circuits.In conclusion, the 293D155X9020A2TE3 is a type of tantalum capacitor that provides reliable, cost-effective performance in a variety of applications. It has a low profile and small size, making it ideal for use in miniature PCBs, and its large capacitance value makes it suitable for noise filtering and decoupling applications. Its ease of use and exceptional reliability make it a popular choice for use in AC circuits, especially in mobile and computer systems.
