Tantalum Capacitors

Tantalum capacitors are widely used these days, particularly in the electrical and electronic industries. They are used for a variety of applications including signal processing, switching, motor control, and power supplies. The specific model, T491A334M035ZT7280, is a surface-mount capacitor with a capacitance of 3.3F, with a voltage rating of 6.3 V.

Application Field

T491A334M035ZT7280 are especially suitable for applications in low frequency circuits or those that require a relatively low voltage but high current-handling capability. These capacitors are often used in LED lighting, LED displays, and microprocessor-based equipment because of its low inductance and low ESR.

Its overall size is also important in many applications, so T491A334M035ZT7280 is a great choice when dealing with size requirements. Additionally, this model offers up to 25,000 hours of life expectancy, making them a great choice for applications that require a long working time.

Working Principle

Just like other capacitors, the T491A334M035ZT7280 works by charging the two metal plates with a specific voltage and storing the charge. This voltage can be adjusted using a voltage regulator or by using a switching circuit. When the two metal plates build up electrical charges, an electric potential is created that determines the voltage that the capacitor is storing.

The voltage stored on the capacitor will remain until there is a change in the electrical field, and when this change occurs, the capacitor will discharge the stored voltage until it reaches equilibrium. Since the voltage changes can occur rapidly, capacitors are ideal for use in high frequency circuits and applications where quick, short pulses are needed.

Safety Issues

T491A334M035ZT7280 capacitors should be handled with care. The maximum permissible working voltage is 6.3 V, and any voltage above this limit can cause permanent breakdown and damage of the capacitor. Additionally, these capacitors should not be exposed to liquids, as they can cause corrosion and other damage to the internal components. Finally, during and after installation, the capacitor should never be in contact with any other part of the circuit and should be kept away from direct sunlight, heat, and moisture.
