Tantalum capacitors are solid electrolytic capacitors that rely on the tantalum metal as an anode. This type of capacitor bridges the gap between the ceramic capacitors and the aluminum electrolytic capacitors. Tantalum capacitors are a type of electrolytic capacitor and offer numerous advantages over other similar components due to the close relationship between the anode and its electrolyte.

The M39003/03-2061 is a product produced by the Vishay Intertechnology and is an SMD Tantalum Capacitor with a size of 2.5mm x 5.5mm. It has a voltage rating of 20V and capacitance of 1,000µF. It has a maximum operating temperature of 105°C and a maximum dissipation of 30W.

The application field of the M39003/03-2061 depends upon its electrical properties and how they meet the requirements of the circuit it’s being used in. This type of capacitor is typically used in applications that require high capacitance values, such as DC-DC converters, pulse shaping and power supply decoupling. It is also used as a high frequency bypass capacitor or as a buffer capacitor in wireless circuits.

The working principle of the M39003/03-2061 is based on the chemical property of the tantalum metal. When an electrical current flows through the anode, it attracts the ions of the electrolyte, which then cover the anode and form a thin layer of oxide. This acts as an insulator and prevents electrical leakage. This is known as electrolytic polarization and is the same mechanism found in aluminum electrolytic capacitors.

The M39003/03-2061 also uses a protective polymer layer on the surface of the anode. This provides the capacitor with increased reliability and stability, and also lowers the equivalent series resistance (ESR) of the capacitor. This feature gives the component its high ripple current capability, making it an ideal choice for applications such as decoupling and voltage clamping.

Finally, the M39003/03-2061 also offers additional benefits such as non-polarity, low ESR values, very stable performance over temperature and current, and intrinsic surge immunity. These features make this component perfect for use in space-constrained and reliability critical applications.

In summary, the M39003/03-2061 is a type of SMD Tantalum Capacitor that offers excellent electrical properties, including high capacitance values, low ESR values, non-polarity, very stable performance, and high ripple current capability. These features make it ideal for use in applications such as DC-DC converters, pulse shaping, power supply decoupling, and wireless circuits.
