Tantalum Capacitors

CWR26HH226JCGA Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitor which use tantalum as a core material for its construction. These capacitors are mainly used in a variety of electronic applications where stability, small size, and high frequency characteristics are needed. They are also popular for being energy-efficient and offering extremely high capacitance values.

The CWR26HH226JCGA is a surface-mount tantalum capacitor. It is made from a combination of electrolyte, a tantalum pellet, and two-terminal seals. These components are then placed inside a porous casing, which is then filled with a conductive liquid, such as alcohol or water. The elements of the capacitor are then sealed off and insulated with an appropriate dielectric material.

The CWR26HH226JCGA is a multilayer electrolytic type, meaning it consists of two layers of conductive material and two layers of dielectric material, with an insulating barrier in between. This allows for a higher capacitance rating per unit and a better electric field insulation. The capacitor typically has a tolerance rating of ±5-10% and an operating temperature range of -55°C to +125°C.

The CWR26HH226JCGA is typically used in filter circuits, DC/DC converters, and signal processing circuitry, especially in audio applications. The capacitor has a wide operating range and can be used in relatively high voltage applications up to 6.3 VDC. On the other hand, its high frequency characteristics and high energy density make it a good choice for decoupling and stabilizing purposes, as well as for charging and discharging applications.

The working principle of the CWR26HH226JCGA is relatively simple. When a voltage is applied, the current will flow through the two layers of conductive material, which will then store the charge on a micro level. The capacitance of the capacitor is determined by the thickness of the dielectric layer, the relative plate area, and the dielectric constant.

To conclude, the CWR26HH226JCGA is a tantalum capacitor which has numerous applications in a range of different electronic devices. It has a multilayer design, allowing for a higher capacitance rating per unit and a better electric field insulation. It is mainly used in filter circuits, DC/DC converters, and audio applications, offering excellent high frequency and energy density characteristics and a wide operating temperature range.
