Tantalum Capacitors

A tantalum capacitor, also known as a tantalum electrolytic capacitor, is an electrical component used to store electrical charge. They are widely used in modern electronics because they are highly reliable, have a small footprint, and offer high capacitance levels in a small package. The 150D564X0035A2T series from Vishay is an example of a tantalum capacitor.

Application Field and Working Principle

Tantalum capacitors are used in high-volume, handling the demands of various electronic devices. In many cases, they are used for decoupling and bypassing power supplies. Other applications include DC-DC converters, power supply filters, voltage regulators, and power amplifiers. They are also used for LED lighting applications, automotive applications, and signal processing.

Tantalum capacitors are polarized components, meaning they have a positive and negative terminal. The physical construction of the capacitor is the same as other electrolytic capacitors; the two main components are the anode and cathode. The anode is made of a solid electrode material, often a sintered tantalum powder, which is surrounded by an electrolyte such as an alcoholic or aqueous solution. The cathode is made up of an inert electrode such as aluminum, which is surrounded by a permeable material such as paper or cloth. This unique combination creates a capacitor with a very high capacitance to volume ratio.

When a voltage is applied to the capacitor, the electrolyte and the material of the anode allow electrons to be transferred from one terminal to the other. This process is known as capacitive charging. This allows the capacitor to store electrical charge, and when the voltage is removed, the electrons will be released, allowing the capacitor to discharge. This process happens quickly and continuously and helps to filter out electrical noise and stabilize voltages.

The 150D564X0035A2T series is a High Temperature, High Reliability, Tantalum/MOLYBDENUM capacitors specifically designed for applications requiring high temperature performance. It is RoHS compliant and has excellent moisture resistance and DF. With its strong construction, Vishay\'s 150D564X0035A2T series can handle higher temperatures up to 125°C and offer a higher vibration and shock resistance, making them suitable for military, industrial and aerospace use.
