Tantalum Capacitors: CWR26HK226JBGC\PR Application Field and Working Principle

A tantalum capacitor, also known as a Ta-Cap, is an electrolytic capacitor which consists of two electrodes, an anode and a cathode, separated by an electrolytic tantalum oxide dielectric. The two metallic plates act as electrical conductors that store charge in a conducting medium called an electrolyte. The anode of the capacitor is made of a tantalum metal oxide while the cathode is made of a material such as aluminum or copper. These materials form a polarized structure, which can store energy in the form of electrical charge.

Tantalum capacitors offer several advantages compared to other types of capacitors. They have high capacitance density, low leakage current, low ESR, and high stability at temperatures up to 200°C. Additionally, tertiary compounds increase the reliability of the capacitor since it is tolerant to high voltage spikes. The capacitance value of a tantalum capacitor is measured in Farads (F) and is expressed as a working voltage rating up to 6.3 Vdc.

Applications

Tantalum capacitors are commonly used in a wide range of electronic products and applications. They can be used in military and aerospace applications where high reliability is a must. Power supplies, digital signal processing, and motion control systems are other applications where tantalum capacitors are commonly used. Furthermore, they are an essential component of computer motherboards, mobile phones, and medical equipment. Another use for tantalum capacitors is smoothing digital signals in audio and video equipment. An analog modulation signal from an audio or video source needs to be protected from the power line spikes, and this is where a Tantalum capacitor can be beneficial.

The CWR26HK226JBGC\\PR is a high frequency tantalum capacitor with a capacitance of 2.2 μF. This particular capacitor is a metal film capacitor, which is characterized by its high temperature and high voltage. It has a voltage rating of 16 Volts and a temperature range of up to 125°C. This makes it ideal for high frequency applications such as amplifiers.

Working Principle

The working principle of a tantalum capacitor is based on the electrolyte acting as an electrical conductor between the positive and negative electrodes. As current passes through the capacitor, a charge is stored within the dielectric and stored within the electrolyte. The stored charge remains in the capacitor until the power supply is removed. This process is known as a capacitor dielectric charging cycle.
