Tantalum Capacitors

Tantalum capacitors are solid electrolytic capacitors utilizing the unique physical and electrical properties of tantalum. They are used in wide range of applications due to their compactness, mechanical robustness and high capacitance per volume. The two most popular types of tantalum capacitors are wet and dry.

199D476X0010DXV1E3 Application Field and Working Principle

The 199D476X0010DXV1E3 is an axial-lead tantalum capacitor with a maximum operating voltage of 20V, capacitance of 47μF ± 20%, and an operating temperature range of 0 to 70°C. This type of tantalum capacitor is ideal for general purpose applications such as automotive, industrial, and digital power thanks to its advantages of low ESR, long life expectancy, high capacitance per volume ratio, and small size.

The 199D476X0010DXV1E3 is a reflow-solderable tantalum capacitor that utilizes solid electrodes for positive and negative sides, and a tantalum pentoxide dielectric material. The two solid electrodes are separated by an anodic oxide film which serves as the dielectric. The oxide dielectric have a very high permittivity, allowing it to maintain a highly uniform electric field over a wide range of operating voltages. The higher permittivity of the dielectric also results in a higher capacitance for a given physical volume, when compared to aluminum electrolytic capacitors.

The device is manufactured using the automotive-friendly press-fit technology, which ensures reliable electrical contact between the lead frame and the capacitor body. High-temperature, reflow solderable terminals provide convenient robotic and manual assembly. The termination is plated for maximum adhesion and corrosion resistance.

The appropriate design of the plastic enclosure prevents moisture damage and imparts physical strength against mechanical pressure and vibration. The enclosed resin is specially designed to handle higher temperature (up to 150°C) for automotive under-hood applications.

The 199D476X0010DXV1E3 is designed to provide a high amount of capacitance in a small volume, making it ideal for power supply and automotive applications. High capacitance ratings, low profile, long life, and superior temperature characteristics give the device a wide range of uses, making it ideal for a variety of applications. This type of tantalum capacitor is especially useful for automotive, industrial, and digital power applications thanks to its low ESR, long life expectancy, high capacitance per volume ratio, and its small size.
