T540D477M003AH8605WAFL Application Field and Working Principle

T540D477M003AH8605WAFL tantalum - polymer capacitors are widely used in consumer electronics, computer and communication equipment, automotive, consumer appliances, and other products. They are ideal for high frequency, low impedance and multitude of board space applications. This type of capacitor offers an excellent combination of low ESR and high capacitance per unit volume. The capacitors are packaged in a very small case, making them highly desirable for small and compact circuit boards.

A tantalum - polymer capacitor works by providing energy storage from an electron flow between two metal plates. The metal plates on the capacitor are also coated with a dielectric layer of tantalum pentoxide. This layer creates an electric field between the two metal plates and stores and releases electrical energy. The dielectric layer also affects the capacitance, or charge storage and discharge capability, of the capacitor.

T540D477M003AH8605WAFL tantalum - polymer capacitors are constructed using a high quality, robust, single-layer Ta2O5 (tantalum pentoxide). This type of capacitor features low effective series resistance (ESR) and is highly reliable. The capacitors are built with excellent electrical properties such as low capacitance variation and good linearity. They also offer excellent thermal stability, making them well suited for high frequency applications.

The maximum operating temperature for these tantalum - polymer capacitors is typically in the range of -55 to +125 degrees Celsius.
