Tantalum Capacitors

Tantalum capacitors are a type of capacitor that is frequently used in electronic circuits. The active component of a tantalum capacitor is made of tantalum, an element that is characterized by a high dielectric constant and good electrical conductivity. Tantalum capacitors are available in two main forms: solid and wet electrolytic.

The TR3E686M020C0150 is a type of tantalum capacitor that is used in many applications. It is a surface-mount, surface-mount tantalum chip capacitor with a capacitance of 20 µF and a maximum operating voltage of 6.3 Vdc. The operating temperature range is between -55 and +125 degrees Celsius.

Application Field

The TR3E686M020C0150 is used in a number of applications, including industrial equipment, automotive systems, power supplies, and consumer electronics. The capacitor’s high temperature range and long life make it ideal for these types of applications. Tantalum capacitors of this type are also used to store electrical energy for a range of devices.

Working Principle

Tantalum capacitors work on the principle of electrolytic capacitance. This means that the capacitor is comprised of two electrodes separated by an electrolytic solution. When a voltage is applied to the capacitor, electrons and ions travel between the two electrodes, resulting in an electrical current. The electrons and ions move back and forth between the two electrodes in a process called diffusion. This process creates an electrostatic field, which is responsible for storing electrical energy.

The capacitance of a tantalum capacitor is primarily determined by the area of the electrode plates. The thicker the dielectric, the higher the capacitance. Capacitors can also store energy by using a dielectric material, such as tantalum pentoxide, with a higher dielectric constant. This increases the capacitance and allows for higher operating frequencies.
