T95R127K010EZAL

Tantalum capacitors are electrical components that store energy in the form of an electric charge between two objects or plates. They consist of two plates, separated by a spacergenerally made of ceramic, which is then soaked in electrolyte and sealed with a metal case. Tantalum capacitors are commonly used to store and release energy quickly—something required in computers, cell phones, digital billboards and other electronic devices. The T95R127K010EZAL is one such type of tantalum capacitor designed for specific applications.

Design & Construction

The T95R127K010EZAL capacitor consists of a tantalum anode and cathode housed in a hermetically sealed metal case. The ceramic and tantalum plates are separated by an electrolytic spacer, which is an insulator, and act as the dielectric material. The plates themselves are composed of special conductive polymers, which are able to absorb and store more energy within the capacitor than regular ceramic or tantalum materials. The spacer\'s insulating properties prevent any unintentional power leakage, ensuring the capacitor\'s maximum energy storage capability.

Working Principle

Tantalum capacitors draw power from the current or voltage source; the majority of this energy is stored in the form of an electric field between the two plates. When the capacitor is discharged, it reverses this process by converting the electric field into current or voltage, depending on the type and application. This conversion is highly efficient, as the internal resistance from the tantalum material is relatively low.

Applications

The T95R127K010EZAL capacitor is used in electronic circuits and systems that have an active power draw that is both low and reliable. It is particularly useful in applications requiring an extended operating period, such as embedded controllers or power distribution systems where device maintenance is either costly or difficult. This type of capacitor is also useful in portable entertainment devices or digital billboards that use energy-efficient optical modulators. This allows them to remain powered for extended periods without needing to be recharged.

Advantages

The T95R127K010EZAL capacitor’s low internal resistance and high capacity storage make it an ideal component for use in operative systems where power is needed for extended periods of time. The hermetically sealed metal case protects the capacitor from environmental degradation and prevention of corrosion caused by air and moisture. As they have no moving parts, these capacitors require little to no maintenance and are reliable in their performance.

Disadvantages

Tantalum capacitors have a lower capacity compared to electrolytic capacitors, and therefore cannot store a large amount of energy. Additionally, they can be damaged due to overvoltage as their units are designed for operating voltages up to a maximum of 50V. Exposing them to high voltage excess of this limit can damage them and even cause them to explode due to the intense heat generated.
