Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor. They are commonly used for decoupling and bypassing applications, as well as in signal processing and power subsystems. The M39003/01-6021H capacitor is an axial lead tantalum capacitor produced by Vishay. This tantalum capacitor type offers high capacitance values, high reliability, and low cost.

Application Field

The M39003/01-6021H has a variety of application fields. Its primary purpose is as decoupling and bypass capacitors in low-power and high-frequency circuits, such as high-efficiency switching power supplies, automotive electronics, and portable consumer electronics. It is also widely used as an input smoothing capacitor in low-noise switching power supplies. The capacitor is also suitable for a variety of other applications, including signal processing, RF applications, noise filtering, and charge-pump applications.

Working Principle

Tantalum capacitors work by storing electrical charge between two electrodes, a positive and a negative. The positive electrode is made from sintered tantalum powder, and the negative electrode is made from a conducting polymer. The charge is held between the two electrodes by a very thin dielectric layer quickly formed between the two when a voltage is applied. This dielectric layer can prevent dielectric breakdown, making tantalum capacitors more reliable than other types of electrolytic capacitors.

An important feature of the M39003/01-6021H is its high capacitance. It can store up to 6021μF per unit volume, much higher than other types of electrolytic capacitors. As a result, it is particularly suitable for applications requiring a high capacitance, such as RF filters and audio power supplies.

The M39003/01-6021H also has a high polarity voltage rating, up to 10V, and a high operating temperature range, up to 125°C. This makes it suitable for a wide range of applications, from low-voltage consumer electronics to high-power automotive systems.

In addition, the M39003/01-6021H has a high ripple current capability, up to 10A. This makes it suitable for applications with high current transients, such as in decoupling and bypass circuits.

The M39003/01-6021H is also very reliable, with a long-term stability and an expected life of up to 2000 hours. This makes it particularly suitable for long-term energy storage applications.
