Tantalum Capacitors

Tantalum capacitors refer to capacitors made from tantalum, an element of the same name, which is used as an anode. It has many advantages such as small size, large capacity, low impedance, low cost, light weight and fast charging time.

The 13008-030KESZ is a type of tantalum capacitor that is widely used in power electronics, such as computers, sound systems, cell phones, and many other electronic devices. It is a surface-mount, 0603 size, and 3-pole version, and is rated for a capacitance of 33μF with an ESR of 35mΩ. As such, it is suitable for use in both high- and low-voltage applications.

Application Field

The 13008-030KESZ tantalum capacitor is used in a wide range of electronic applications, such as motherboards, sound systems, video recording equipment, and in general consumer electronics. It is well-suited for use with integrated circuits, power supplies, and high-frequency switching circuits. In addition, this type of capacitor is often used for DC-DC converters, voltage regulators, and in motor drives as well.

Working Principle

Tantalum capacitors are polarized and have a specified positive and negative terminal. The positive terminal is the anode and the negative terminal is the cathode. The 13008-030KESZ capacitor is a polarized type with a non-polarized capacitor element and a self-healing construction. This means that any damage to the capacitor’s dielectric layer will be automatically repaired by an electro-chemical process.

The capacitance of a tantalum capacitor is determined by the anode and cathode’s capacitive reactance, which is inversely proportional to their applied voltage. This phenomenon is known as capacitive reactance inversion, and is what enables a tantalum capacitor to provide excellent high frequency performance. In addition, the 13008-030KESZ capacitor is often used in low-voltage applications due to its low ESR rating, which makes it desirable for use with power supplies.

Conclusion

The 13008-030KESZ tantalum capacitor is a popular and reliable component used in a wide range of electronic applications. Its small size, low impedance, low ESR, and self-healing construction make it well-suited for use in high- and low-voltage applications. The capacitance of the capacitor is determined by the anode and cathode’s capacitive reactance, and its high frequency performance is excellent.
