Tantalum Capacitors

Tantalum capacitors are a type of electrical component used in a variety of different applications. A tantalum capacitor is an electrolytic capacitor that generally features a high capacitance, low ESR, and a wide operating temperature range. These capacitors are extremely reliable and have excellent frequency characteristics. They are typically made from a tantalum powder which is pressed into a solid block, then insulated with a dielectric material. The most common type of tantalum capacitor is the three-terminal polarized capacitor, however there are other types as well.

The code 199D226X0035E6B1E3 refers to a specific type of tantalum capacitor. This is a three-terminal axial leaded capacitor with a maximum working voltage rating of 35V. The maximum capacitance of this device is 22uF with an allowable tolerance range of +/- 20%. The capacitor is also a 100% surge current tested device, meaning it has been tested for its ability to withstand a large surge current.

Tantalum capacitors are used in a variety of applications. Some of the most common uses include power supply filtering and decoupling, signal coupling and bypassing, and DC blocking. In a power supply filtering application, the capacitors help to reduce noise and smooth out the DC voltage ripple. In a signal coupling or bypassing application, the tantam caps act to isolate a signal or transfer it between two points at different frequencies. In a DC blocking application, the capacitor acts as a high-impedance load and blocks any DC current from flowing.

The working principle of a tantalum capacitor is fairly simple and is based on the principles of electrochemistry. Basically, a current is run through the capacitor and electrical energy is stored. During charging, the applied voltage causes an electrochemical reaction which results in the deposition of positively charged tantalum ions on the negative terminal. During discharging, the opposite process occurs and the ions are released, returning to the positive terminal. This action results in electrons being pushed out of the negative terminal, thus creating an electrical charge.

In conclusion, tantalum capacitors are reliable, high-performance, electrolytic capacitors with a wide range of applications. They are commonly used in power supply filtering, signal coupling and bypassing, and DC blocking. The working principle is based on electrochemical reactions which transfer energy between the terminals in order to create an electrical charge. The code 199D226X0035E6B1E3 specifically refers to a three-terminal axial leaded capacitor with a maximum working voltage rating of 35V and a maximum capacitance of 22uF.
