Tantalum Capacitors

Tantalum capacitors, also known as Ta-Capacitors, are a type of electrolytic capacitor widely used in consumer electronics and electrical engineering. These capacitors are usually characterized by a "spill-proof" case, with electrodes on either side that are made out of a combination of tantalum and other materials such as nickel, aluminum or copper. They use a dielectric material, usually an organic polymer, to regulate the flow of electrons between the electrodes and the capacitor\'s inner terminals. The capacitance of tantalum capacitors varies depending on the size and shape of the capacitor.

One popular example of a tantalum capacitor is the CWR11JH225KB. This capacitor has a lead pitch of 2.5mm and a maximum voltage rating of 25V. Its capacity ranges from 0.22F to 1.5F. Its temperature range operates between -40 and +125 degrees Celsius.

The main application of the CWR11JH225KB is in low-voltage and high-frequency electronic systems. This can include circuits that require a steady and reliable DC voltage, such as analogue and digital audio amplifiers and computer circuits. The CWR11JH225KB is suited for both capacitive-coupled and feedback circuits, and is typically used in high-performance audio and video applications.

The working principle of the CWR11JH225KB is based on the electrochemical principle of charge redistribution. When a current is applied to the capacitor, the tantalum ions move and form a metal shell (or capacitor dielectric) that stores charge. The charge distribution of the capacitor is determined by the amount of current that is applied to the capacitor. When the current is removed, the charge on the capacitor will remain and the capacitor will act as a voltage source.

Tantalum capacitors are renowned for their stability, low leakage and wide temperature range. The CWR11JH225KB is one such example that is ideal for applications in areas such as automotive electronics, portable audio and telecommunications equipment. Thanks to its robust construction, this capacitor is able to effectively handle high frequency operations and fluctuations in temperature while maintaining its charge.
