Tantalum Capacitors

Tantalum capacitors are widely used due to their low price and low equivalent series resistance (ESR) compared to conventional aluminum electrolytic capacitors. Capacitance values of these capacitors range typically from 0.1 µF to 10mF, and voltage ratings vary from 2.5V to 75V. The tantalum capacitors are also used as memory backup for computers as well as for oscillator circuits.Today, the M39003/09-0124 is one of the most popular tantalum capacitors available in the market. This device has capacitance values from 2.2μF to 1500μF with a voltage rating of up to 25V. It is characterized by low ESR (<20mΩ), low internal inductance (<200nH) and high ripple current. The capacitor comes in a small, surface mount package and is ideal for use in high-density applications.

M39003/09-0124 Application Field and Working Principle

One of the applications of M39003/09-0124 tantalum capacitors is in high frequency power conditioning circuits, where the capacitor helps to reduce noise, while providing the desired voltage. The capacitor also acts as an energy storage device for circuits that require constant voltage or current. Additionally, it can be used for circuit decoupling, filter circuits, energy management and AC/DC converters.

The working principle of a tantalum capacitor is based on the concept of electrolytic action. The capacitor consists of a cathode composed of metallic tantalum powder, and an anode made of manganese dioxide. The capacitor also has a proper voltage rating, and the insulating media is an organic polymer electrolyte. When an external voltage is applied, an electric field is established between the tantalum cathode and the manganese dioxide anode, and this causes the ions of the electrolyte to move towards the anode. As a result, the tantalum cathode and manganese dioxide anode become charged and form a capacitance.

The size of M39003/09-0124 tantalum capacitors is much smaller than that of conventional electrolytic capacitors. This makes it ideal for high-density applications such as power systems, portable electronics and other industries. It has a long life cycle and higher stability than conventional electrolytic capacitors, making it highly reliable.

The M39003/09-0124 tantalum capacitor is a reliable, compact and low-ESR design that is suitable for demanding applications where high performance, low cost, and space savings are of paramount importance. It is widely used in many applications due to its high reliability and low cost, and its small size makes it ideal for use in PCBs.
