Aluminum electrolytic capacitors are widely used in almost all facets of electronic applications. In most instances, they are the main link within a circuit or on a board, serving as a means to store and transfer electronic energy as and when required. One such type of capacitor is the TVA1438.

The TVA1438 is categorized as a Aluminum Electrolytic Capacitors and is usually used in applications where an elevated capacitor voltage rating and volumetric efficiency is required, such as where input supply voltage jumping and system reversing is anticipated. As such, the TVA1438 is a fairly substantial and rugged component, measuring 33 mm (1.3″) in diameter and 10 mm (0.39″) in height, despite its actual size & weight enabling the internal components to be reliably positioned and arranged.

The basic structure of the TVA1438 consists of two main parts; an aluminum shell or casing which imparts all the electrical, mechanical, and environmental protection together with an anode or cathode foil which forms the attraction of the device. For additional protection, the device is then filled with an electrolytic solution material which has been specially formulated for both the application and the environment under which the device is exposed to. Finally, the whole apparatus is then hermetically sealed off with an outer shell.

The electrical properties of the TVA1438 are defined by the following attributes; The capacitance values range from 330uF to 470uF with a rated working voltage of 16V to 36V. The low ESR (Equivalent Series Resistance) enabling excellent frequency response while the high ripple current rating ensures that there is no risk of damage due to current surges. Finally, the device boasts a life cycle expectancy of 10,000 hours.

In summary, TVA1438 aluminum electrolytic capacitors are designed and formulated to meet the requirements of applications where high voltage, small form factor, and low ESR, coupled with a long and reliable life cycle is compulsory. Its low inductance, ceramic dielectric, and efficient shielding all work together to enable continuous, reliable, and predictable performance throughout its life.
