Tantalum Capacitors

150D473X0100A2BE3 is a type of tantalum capacitor which are utilized for specific applications and working principles. As tantalum capacitors have relatively small form factors, they are repeatedly used to provide high capacitance within limited space. This makes them ideal for handheld consumer electronic devices which require more efficient use of space.

Application Field

The 150D473X0100A2BE3 has a number of application avenues for which it can be used. Such applications include energy storage, linear decoupling, power supply bypassing, and filtering in process control units. They are also utilized as pulse and signal shunts and current filters. A distinct advantage of these capacitors is that they are widely used across all commercially available power grades, ranging from 125 to 400 volts.

Working Principle

Tantalum capacitors, including 150D473X0100A2BE3, rely on the mechanical structure of a solid-state dielectric in order to produce a stable electrical capacitance. This process known as ‘tantalum electrolytic capacitance’ and is produced in a three step process. First, tantalum powder is pressed into a pellet shape. This is then wrapped in an ultra-thin metal foil which serves as one electrode. The tantalum pellet is then coated with a seed dielectric and immersed in an electrolytic solution. Finally, a second electrode is exposed to the solution which creates an oxide layer, forming the dielectric.

The oxide layer that is formed by the two electrodes provide the electrolytic capacitance. The oxide layer works to selectively allow current to flow through it but passive current, like an electric charge, to move freely through it. This allows for initial high-level causes, such as a power surge, to be more effectively dampened.

Advantages of 150D473X0100A2BE3

There are several advantages that tantalum capacitors, such as 150D473X0100A2BE3, possess over other types of capacitors. These include:

• High volumetric efficiency: given their small size, they are able to store a greater amount of energy than other types of capacitors.
• High stability: thanks to the use of solid-state dielectrics, there is virtually no risk of accidental short-circuits.
• High temperature range: thanks to their reliable dielectric characteristics, they can be used in harsh environmental conditions where the temperature exceeds the recommended range for other types of capacitors.
• Low leakage: the oxide layer in tantalum capacitors is produced in a highly controlled and monitored environment, thereby ensuring that the capacitance is sealed in tightly with no risk of leakage.
• Low dissipation: the higher temperatures produced by tantalum capacitors during operation does not affect performance and so offers a lower dissipation.
