Tantalum capacitors are solid capacitors that use an oxide-coated tantalum wire or a tantalum-polymer base and a metallic electrolyte. Tantalum capacitors provide a variety of advantages over aluminum electrolytic capacitors, including higher capacitance and lower leakage current. B76004E6879M040 is a type of Tantalum - Polymer Capacitors.

Tantalum - Polymer Capacitors provide a high volumetric efficiency as well as superior high temperature characteristics compared to other types of capacitors. The B76004E6879M040 is a surface mount tantalum capacitor with capacitance values from 1 microfarads up to 100 microfarads. It has an operating temperature range of -55°C to +125°C, and a voltage rating of 6.3 VDC.

The B76004E6879M040 tantalum capacitors are mainly used in high temperature, high frequency and low power applications, such as switch mode power supplies, DC/DC regulators, and clock oscillators. They are also used in motor control applications that require low ESR and good ripple handling ability. The B76004E6879M040 is particularly suitable for use in applications involving high temperature and high frequency, such as automotive infotainment systems.

The working principle of the B76004E6879M040 is based on the process of electrochemical migration. The tantalum powder is soaked with electrolyte and then heated up to about 1200°C. During this process, the tantalum particles become electrically charged and migrate in an electrochemical reaction. This reaction forms a thin, strongly adherent film on the tantalum grains that protects them from corrosion and provides the electrical connection between the opposing plates. This process is known as the oxidized tantalum process.

The B76004E6879M040 also has a number of features that make it advantageous over other types of capacitors. It is RoHS compliant, offers low impedance and ESL, has low ESR and long life, is mechanically and thermally stable, and provides excellent capacitance stability.

The B76004E6879M040 capacitors offer a wide range of benefits for a variety of electronic applications. In addition to its high temperature and high frequency performance, the B76004E6879M040 also offers low ESR and excellent ripple handling ability. It is also RoHS compliant and provides excellent capacitance stability. The B76004E6879M040 is an ideal choice for applications such as automotive infotainment systems and motor control applications.
