Electrolytic capacitors are electrical components primarily used to store energy and divert current. These crucial components are utilized extensively in the electronics industry, providing energy storage, power condition, DC link filtering and power factor correction. Aluminum electrolytic capacitors offer a reliable and cost-effective solution in various applications. The TVA1408 is one such aluminum electrolytic capacitor.

The TVA1408 is a long life, ultra-low voltage aluminum electrolytic capacitor designed specifically for low voltage ac/dc applications. Its low profile design makes it perfect for applications where space is limited and its wide temperature range ensures reliable operation in a variety of working conditions. The TVA1408 is a non-solid polymer electrolytic capacitor with an aluminum case and polypropylene dielectric. Its electrolyte is composed of an organic solvent, making it environmentally friendly.

In terms of application fields, the TVA1408 is used predominantly in ac/dc power supplies, power conditioning equipment, medical equipment, industrial automation systems, and motor control systems. It is also found in uninterruptible power systems, switching power supplies, and battery-backed up systems. The TVA1408 provides excellent performance in all these application fields and more, making it a desirable choice for many applications.

The TVA1408 is known for its long life and reliable performance in challenging environments. It operates with a wide voltage range from 1.2 volts to 500 volts, and its maximum temperature range of -55⁰C to +105⁰C means it can operate in some of the most extreme environments. Its life expectancy at a rated temperature of 105⁰C and a rated voltage of 125 volts is 4,000 hours, while at a rated temperature of 85⁰C and a rated voltage of 25 volts it is 9,000 hours.

The TVA1408’s working principle can be broken down into two parts: electrolysis and capacitance. When a voltage is applied, galvanic couples are created in the electrolytes, which separate into positively and negatively charged ions that migrate towards the anode and cathode, respectively, charging the capacitor. The capacitance refers to the physical properties of the capacitor, namely its ability to store and transfer energy. The amount of charge a capacitor can hold depends on its size, shape and the material of its electrodes.

In summary, the TVA1408 is a reliable and cost-effective aluminum electrolytic capacitor intended for use in a variety of low voltage ac/dc applications. Its wide voltage range and long life make it a desirable choice for many applications. Its working principle consists of two components, electrolysis and capacitance, resulting in a reliable performance in challenging environments.
