TPSD226M035H0200

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of capacitor that is particularly well-suited for use in applications requiring high capacitance values in a small package size. The TPSD226M035H0200, for example, is a tantalum capacitor with a voltage rating of 2.5 Vdc, a capacitance of 226 µF, and an operating temperature range of -55°C to 125°C. The TPSD226M035H0200 is a surface mount device, meaning it is designed to be mounted on the surface of a printed circuit board.

The working principle of a tantalum capacitor is similar to that of any other type of capacitor; it stores electrical energy using the attraction of positive and negative charges on two electrodes. In the case of tantalum capacitors, the electrodes are made of porous tantalum metal and the dielectric is a thin layer of solid electrolyte.

When a tantalum capacitor is connected to a circuit, an electric potential (voltage) is applied across the electrodes, creating an electric field in the dielectric layer. This electric field causes ions from the electrolyte to be drawn towards the negative electrode, forming a capacitive layer. While this capacitive layer continues to grow in size, the positive electrode remains unchanged, allowing the capacitor to maintain its stored charge.

The TPSD226M035H0200 has a wide range of applications, including power management, backup power, and decoupling. It is well-suited for use in automotive, industrial, portable, and military electronics due to its high capacitance, small package size, and high temperature resistance. The capacitor is also RoHS compliant, meaning that it meets the stringent standards of the European Union Directive on the Restriction of Hazardous Substances (RoHS).

In conclusion, the TPSD226M035H0200 is a high performance tantalum capacitor that is well-suited for use in a wide range of applications. The capacitor provides a high capacitance value in a small package size and is resistant to temperature extremes and RoHS compliant to ensure safety and longevity. The working principle of a tantalum capacitor is similar to that of any other type of capacitor and involves the attraction of positive and negative charges on two electrodes, creating an electric field in the dielectric layer.
