Tantalum - Polymer Capacitors

Tantalum - Polymer Capacitors are one of the most advanced and useful advancements in capacitor technology. They offer high levels of performance, and relatively low costs, allowing them to be used in many industries and applications. The B76004D4779M25K2 is a good example of this technology, as it offers high levels of performance, a wide range of voltages, and is highly reliable.

What are Tantalum - Polymer Capacitors?

A Tantalum-Polymer Capacitor is a type of capacitor that combines features from both types of capacitors. They are made up of a tantalum oxide layer, sandwiched between two pieces of ceramic or dielectric material. This layer is then topped off with electrodes, allowing a charge to be stored, and released, when needed. The electrodes can be made out of different metals, depending on the application.The main advantage of this type of capacitor is that they are quite small, and offer high levels of capacitance, meaning they are ideal for use in applications that demand a significant amount of surface area. This makes them particularly suitable for use in cell phone, tablet and laptop batteries, as well as other portable electronics, where surface area and size are critical. They can also be used to store high voltages, as well as resist high frequencies.

The B76004D4779M25K2

The B76004D4779M25K2 is a tantalum - polymer capacitor from TDK, a leading manufacturer of capacitors and other components. This particular model is a Low ESR, single-terminal capacitor, with a high capacitance rating of 47μF and a wide range of voltages from 6V up to 35V. It is also very reliable, with high heat resistance, shock resistance and vibration, as well as a long life span of up to 12,500 hours, making it a suitable choice for industrial and commercial applications.

Applications

The B76004D4779M25K2 can be used in many different applications, ranging from cell phones and tablets to industrial machinery. It is often used in applications that require a large amount of surface area, such as in laptop batteries, as well as for storing and releasing high voltages, such as in surge protection circuits. It is also used in mostly in high-frequency circuits such as in power supplies, switch-mode power supplies and DC-DC converters.

Working Principle

The working principle of the B76004D4779M25K2 is simple. It consists of two electrodes, one made of tantalum oxide and one made of a ceramic material. When a voltage is applied to the electrodes, it creates an electric field that causes electrons to flow from one electrode to the other. This flow of electrons creates a charge, which is stored in the tantalum oxide layer. When the voltage is removed, the charge dissipates, allowing the capacitor to discharge.

Conclusion

The B76004D4779M25K2 is a perfect example of the advanced technology used in Tantalum - Polymer Capacitors. It offers high levels of performance, along with reliability and a wide range of voltages, making it suitable for a range of electronic applications. It works by creating an electric field between its two electrodes, which allows it to store and release charge when needed. This makes it an ideal choice for use in cell phones, tablets and other portable electronics, as well as for storing and releasing high voltages in industrial and commercial applications.
