Tantalum Capacitors

Tantalum capacitors are widely used in electronic circuit applications such as memory systems, CPU cache, power supplies, digital signal processing, and audio/video systems. A T491C336M020AT tantalum capacitor is a type of tantalum capacitor that is used specifically in high power applications.

Application Field

The T491C336M020AT tantalum capacitor is an ideal choice for applications that require high operating temperatures. It is commonly used in automotive, consumer and computer circuits, as well as many other applications. It can handle temperatures up to 125°C and provides an enhanced surge current capability.Thanks to its compact design, this type of capacitor can be used in space-constrained applications. It is much smaller than conventional electrolytic capacitors but delivers a higher output voltage rating and a longer life span when compared to electrolytic capacitors.

Working Principle

Tantalum capacitors work on the same principles as other types of electrolytic capacitors. Inside the capacitor, electric charge is stored on two metal plates. A third plate is usually placed in the center of the capacitor, and it is connected to a voltage source. When a voltage is applied to the capacitor, electric charge accumulates on the first two plates, creating a potential difference between them. This potential difference is what allows the capacitor to hold electric charge.The T491C336M020AT tantalum capacitor utilizes a tantalum anode which is anodized with a barrier layer of oxides. This layer of oxides helps slow down the discharge process and provides high temperature stability. The cathode of the capacitor is a porous structure that contains a chemical solution known as an electrolyte. When the voltage is applied to the capacitor, the electrolyte solution creates an ionic path for electrons to flow. This allows electric charge to be released from the anode and collected on the cathode, creating an electric field.

Conclusion

The T491C336M020AT is a popular choice for high-power applications that require adequate temperature stability and a long life span. It provides high output voltage ratings and a low leakage current. Additionally, it is smaller than conventional electrolytic capacitors, making it aesthetically appealing and suitable for space-constrained applications. Whether in automotive, consumer or computer applications, the T491C336M020AT will provide reliable and efficient capacitor performance.
