Tantalum Capacitors

Tantalum capacitors, which are also referred to as tantalum electrolytic capacitors, are a subcategory of electrolytic capacitors. Tantalum capacitors are extremely versatile, ultra-compact components which are used in a wide array of electrical and electronic systems and circuits. Tantalum caps are often the component of choice in a device or circuit requiring capacitors due to their low cost, high capacitance, and for high-temperature operation.

150D333X9100A2B Application Field

The 150D333X9100A2B series of tantalum capacitors is a two-lead, subminiature, solid polymer device. It uses an anode composed of sintered sleeve pellet material and requiring no extra terminal connections for the case. Because of its design, the 150D333X9100A2B is well-suited for applications containing high electronic noise. Examples of devices that use the 150D333X9100A2B series include DC/DC switchmode converters, AC/DC inverters, switching regulators, signal processing, and other industrial and computer systems.

150D333X9100A2B Working Principle

The 150D333X9100A2B is essentially two distinct storage elements; a negatively charged anode and a cathode connected through an electrolyte. The anode is made of tantalum, while the cathode is composed of oxide material, which also serves as the dielectric material for the capacitor. When the capacitor is connected to a voltage source, current passes through the electrolyte and onto the anode, which causes the anode to increase in voltage. This in turn allows for the capacitor to store charge in the form of a polarized electric field between the anode and the cathode.

The anode and the cathode are attached to each other with either radial or axial leads. These leads provide secure connections for the electrical current to flow through. The leads can also be soldered to a circuit board for permanent attachment. Once properly wired, the 150D333X9100A2B can remain connected for long periods of time without the need for regular maintenance or replacement.

Conclusion

Tantalum capacitors are highly versatile components which are used in a variety of applications. The 150D333X9100A2B series of tantalum capacitors are subminiature, two-lead devices ideal for for industrial, computer and signal processing applications due to their low cost, high capacitance and high temperature operating range. Their ability to store charge in the form of a polarized electric field between two electrostatic plates, knowns as the anode and the cathode, is what allows the capacitor to function.
