Tantalum Capacitors

Tantalum capacitors are distinct types of capacitors which are made with tantalum metal as anode and are notable for their small size, high capacity, long life-span and low cost. The 150D824X0050A2TE3 is a surface mount, tantalum polymer capacitor that is especially suited to a variety of application due to its excellent electrical and physical properties.

Tantalum polymer capacitors have a greater volumetric efficiency than other capacitors, which means that they have a greater capacitance per unit volume. The specific unit discussed in this article, the 150D824X0050A2TE3, has a rated capacitance of 4.7µF, and is packaged in a case measuring 2.5 × 1.25 × 1.125 mm. This makes it the ideal choice for various PCB mounting applications where space is a major factor.

Application Fields

Tantalum capacitors are used in applications which require very high volumetric efficiency such as in electronics, automotive, and communications. The 150D824X0050A2TE3 is especially well suited for applications which require high capacitance in a small area such as consumer electronics, automotive, and medical devices. The low ESR values of the 150D824X0050A2TE3 makes it especially suitable for switching power supplies and DC/DC converters.

Working Principle

Tantalum capacitors are essentially electrochemical devices that rely on the formation of an electrolyte between a pair of electrical contacts and a unipolar electrolyte. This electrolyte acts as a kind of dielectric material that provides the necessary insulation between the two contacts. These two contacts can be a combination of metal or polymer films, and the electrolyte may be an organic or inorganic material. The 150D824X0050A2TE3 uses a tantalum salt electrolyte instead of the conventional organic or inorganic materials.

When a voltage is applied across the terminals of the 150D824X0050A2TE3, the electrochemical process of the electrolyte creates a capacitance which stores the energy between the two plates. When the voltage across the capacitor decreases, the capacitance along with the charge stored in the capacitor is released.

Conclusion

The 150D824X0050A2TE3 is a highly specialized, low-cost, surface mount solid tantalum capacitor that is suitable for use in many different applications. Its combination of high capacitance per unit volume, low ESR ratings, and highly robust construction makes it a valuable choice for applications where size and efficiency are crucial.
