Tantalum - Polymer Capacitors

T540D477M003DH87057610 is a component belonging to the class of capacitors known as "tantalum - polymer capacitors". These capacitors are a type of electrolytic capacitor which makes use of a tantalum-oxide or Ta2O5 film, dissolved in a polymer matrix to form a type of electrode, making it a hybrid capacitor. This capacitance value is stable over a wide range of frequencies and temperatures, hence the high performance and reliability of these capacitors both in terms of electrical and mechanical characteristics.

Application Field and Working Principle of Tantalum - Polymer Capacitors

T540D477M003DH87057610 capacitors are widely used in a variety of applications, including DC-DC converters, computer memory systems, voltage regulators, power transformers, laptops, smartphones, and medical electronics. They provide higher current capabilities than similar components and are able to handle a larger range of electrical and mechanical stress in comparison to other types of capacitors. The basic working principle of this type of capacitor is to store electrical energy, much like a battery, and provide a direct current discharge when required. This is accomplished by the use of an electrostatic charge stored in an electrolyte which is controlled by a conductive material (e.g. metal plate). This metal plate works as a bridge between the electrolyte and the capacitor substrate. The material of the plate, which can be distributed over the entire surface of the capacitor substrate, is known as the capacitor dielectric and as such, affects the capacitance\'s ability to store electrical charges and withstand voltage changes.

When electrical current is applied, an electric field is created between the conductive plate and the electrolyte, reducing the amount of energy the electrolyte can store. This results in a decrease in the capacitor’s capacitance. Conversely, when a current is removed, the electrolyte absorbs and stores the energy, thereby increasing the capacitance. In this way, the capacitance of a tantalum - polymer capacitor rises and falls accordingly with the changes in currents.

In terms of its electrical characteristics, tantalum - polymer capacitors typically feature high ripple current, low ESR (Equivalent Series Resistance) and high temperature capability of up to +125°C. This makes them highly suitable for power electronics applications. These components are also highly reliable, as their construction makes them highly resistant to short-circuit events and physical damage. Furthermore, the use of non-blended dielectrics makes these capacitors highly stable in terms of temperature highly and frequency. As such, the capacitance remains consistent and stable over time. This higher stability also enables a wide range of potential applications, including in the automotive and medical electronics sectors.

In summary, T540D477M003DH87057610 capacitors make use of a hybrid (tantalum-oxide/polymer) dielectric, resulting in high performance and reliability, along with excellent electrical characteristics. Their widespread use in multiple sectors, such as in power electronics, automotive and medical electronics, is a testament to their high performance and reliability.
