Tantalum Capacitors

Tantalum capacitors are capacitor components commonly used in electronic circuits. They are widely used in various electronic equipment, such as mobile phones, computers, digital cameras and other electronic equipment. Its biggest characteristic is high capacitance in a small package, as well as excellent frequency response and long-term stability. The common types are tantalum beads, also known as tantalum disk capacitors.

199D226X9025DXV1 Application Field and Working Principle

The 199D226X9025DXV1 is a type of Tantalum Capacitor. It is a long-life, high-temperature radial leaded tantalum capacitors that offer a broad range of capacitance values and voltage ratings. They are manufactured from high-temperature 127°C Mn04+ electrolyte and tantalum core powder. This capacitor is ideal for use in extremely high humidity, high temperature, high vibration, and low ESR applications.

The 199D226X9025DXV1 capacitor is constructed with two tantalum electrodes sandwiched between an anode and cathode back plate bonded to each other by a dielectric layer. The anode and cathode plates are formed by pressing and sintering tantalum powder. The anode comprise beads of tantalum surrounded by an insulating layer. The anode and cathode plates are electrically connected to the leads. When a voltage is applied, a current flows between the anode and cathode plates, charging or discharging the capacitor. This charge creates an electrostatic field across the dielectric, producing a capacitive effect.

Tantalum capacitors are generally used in high-power devices, typically in the range of microfarads, such as power supplies and motors. Due to their high capacitance and efficient construction, they are also used in high-frequency circuits, such as filters and low-power circuits where small capacitance is desired.

As tantalum capacitors have a relatively high capacitance-to-volume ratio and low ESR value, they offer high capacitance stability, long life, and reliable ESR performance even in extreme environmental conditions. Moreover, the use of manganese-oxide electrolytes has an excellent effect on the performance of the capacitor, such as providing reversibility and low leakage current. Furthermore, these capacitors offer low impedance noise, superior temperature stability, and long-term high frequency stability.

In summary, 199D226X9025DXV1 capacitors provide high capacitance and stable performance in a wide range of applications. The long life and high temperature ratings of the capacitor make them ideal for use in high-humidity, high-temperature, high-vibration, and low ESR applications, including power supply and motor applications.
