Tantalum - Polymer Capacitors

T540D226K020DT8505 capacitors are part of a class of tantalum capacitors, which are very much akin to electrolytic capacitors. The main differences between these two classes of capacitors is that tantalum capacitors are much smaller and can support higher levels of capacitance, as well as a wider voltage range.

Tantalum - polymer capacitors are a type of electrolytic capacitor constructed with a conductive polymer electrolyte between two sheets of conductive foil, one of which is the anode (positive terminal) and the other the cathode (negative terminal). This type of capacitor exhibits high levels of capacitance, low equivalent series resistance (ESR), and a superior ripple current withstanding capability. The combination makes this type of capacitor ideal for many high-power/high-frequency applications.

T540D226K020DT8505 is one of the most popular type of tantalum - polymer capacitors. It is used in many consumer products, including computers and smartphones. It has a voltage rating of 2.5V, tolerance of ±20%, and a capacitance of 22μF. Its operating temperature range is –55°C to +125°C for reliable performance in extreme temperatures. Due to its relatively low voltage rating and small size, this type of capacitor is mostly used in power circuits for decoupling, energy storage, and other low voltage applications.

The working principle of a tantalum - polymer capacitor is basically the same as for other types of electrolytic capacitors. The anode and cathode are connected to a source of voltage and a common ground. When voltage is applied to the anode, a positive charge accumulates on the anode, and a negative charge accumulates on the cathode. This creates an electrical potential, which serves as an energy storage device.

Tantalum - polymer capacitors offer numerous advantages over traditional electrolytic capacitors. They are often much smaller and lighter than electrolytic capacitors, and they require much lower operating voltages. This makes them ideal for applications where low voltage and space are both requirements. They also offer superior temperature stability, which makes them suitable for high-temperature/high-power applications.

T540D226K020DT8505 is a versatile and reliable capacitor that is ideal for many consumer and industrial applications. Its small size, high capacitance, and low voltage requirements make it well suited for portable devices and low voltage, high frequency circuits. Its temperature range makes it suitable for a wide range of applications, and its superior ripple current withstanding capability makes it ideal for power conditioning of digital signals and filtering of power lines.
