Tantalum Capacitors

Tantalum capacitors are special type of surface-mount capacitors used in electronic components and electronic design systems. They are composed of a tantalum anode and a polymer dielectric layer, with a tantalum wire connected between the anode and cathode. The tantalum wire and anode of the capacitor act as electrodes and the anode is usually coated with a layer of tantalum oxide in order to provide electrical insulation and protection. The dielectric layer is formed by a dissipation of the electric field, creating a capacitance between the two electrodes.

195D474X0035B2T Application Field and Working Principle

The 195D474X0035B2T is a high reliability Tantalum Electrolytic capacitor with a rated voltage of 25V DC and a rated capacitance of 47µF. It is a polarised capacitor with a higher capacitance-to-voltage ratio than other types. This capacitor is able to offer stable performance and low cost. It has an effective operating temperature range from -55℃ to +125℃.

The 195D474X0035B2T uses tantalum pentoxide (Ta2O5) as its dielectric, allowing it to achieve greater capacitance for given physical size compared to other types of capacitors. Its packaging uses a metallized steel core that provides EFD to its outer casing, ensuring the capacitor’s electrical integrity and shielding properties. The 195D474X0035B2T can be used in applications that require higher Ripple Currents, or those that need high-speed transient response.

The working principle of the 195D474X0035B2T centers around the interaction between the electrodes and the dielectric layer. When the capacitor is connected to a power source, a current flows through the capacitor, which causes a voltage drop across the electrodes. This voltage drop transfers a charge across the dielectric layer, stored in the form of electrical energy.

Since tantalum capacitors are high reliability components, they are ideal for applications that require high reliability such as Military, Aerospace and Medical electronics. In addition, their long life, low ESR and low cost make them well suited for capacitor storage and power electronics, machine building, and many other fields.
