Tantalum capacitors are one of the most widely used types of capacitors in the electronics industry. They have a wide variety of applications, from high frequency in cell phone manufacturing to memory storage in computers. The F920J225MPA is a capacitor of this type, and its application field and working principle is detailed below.

About F920J225MPA

The F920J225MPA is a surface mount tantalum capacitor housed in a Bi-Polar plastic body which is rated at 4.7µF and 25V. It has a short lead time of 4 - 6 weeks and is used in the design of low leakage, high temperature and low profile circuits. It offers excellent performance characteristics, including low ESR and ESR stability, as well as excellent temperature characteristics and long life reliability.

Application Field

Tantalum capacitors are used in a wide range of electronic products and systems. They are used in the design of high frequency, long life mobile and laptop applications, portable instrumentation, monitors, power supplies, and PCMCIA slots. They are also used in embedded designs, such as engine controllers and communications equipment. The F920J225MPA, in particular, is used for memory storage and hold-up capacitors in computers.

Working Principle

Tantalum capacitors, such as the F920J225MPA, are different from other types of capacitors because they use a dielectric of tantalum pentoxide (Ta2O 5 ) instead of the usual paper, mylar, ceramics, and the like. This material not only offers advantages in terms of capacitance, but also allows for a higher voltage than a capacitor of a similar size. The working principle of a tantalum capacitor is based on a simple theory: electrons are attracted to the positive charge on the terminal when a voltage is applied across its leads. This induces an electric field between the two electrodes, which creates a charge on the dielectric, resulting in a capacitive effect.

The F920J225MPA is a great example of a tantalum capacitor and its variety of uses. Due to its great electrical characteristics and excellent temperature resistance, it is a highly usable component that can provide power to many circuits. Its wide range of applications makes it a great choice for any designer.
