Tantalum capacitors are widely used in electronics applications today, because of their high capacitance, small size, low cost, and low voltage drop compared to other capacitor types. The TAJD685M050RNJ is a miniature surface-mount capacitor constructed with manganese dioxide and tantalum electrolytic dielectric, adding to the increasing trend of surface-mounted components in advanced electronic circuit design. It is part of the “J” series of KEMET tantalum capacitors. This series features extremely low current leakage, long-term reliability, and a very low ESR.

Application Field:

The TAJD685M050RNJ is a high-precision, very small surface mounted tantalum capacitor specifically designed for use in military, aerospace, and commercial decoupling applications. It is especially suitable for power and storage capacitor solutions operating at a high temperature range. Some of the typical applications are filtering of DC ripples, coupling of AC signals, and general-purpose DC blocking.

Working Principle:

The TAJD685M050RNJ works on the basis of the same principles as all other tantalum capacitors. It is composed of a tantalum pellet, surrounded by an electrolytic manganese dioxide dielectric. It has two electrical contacts, which are connected to two plates, called the anode and cathode. When an electric current is applied to it, an electric field is generated across the dielectric, and the capacitor starts to store the electric energy. The total energy stored within the capacitor is proportional to the amount of electrical charge stored.

The TAJD685M050RNJ uses a sintered manganese dioxide as the dielectric, and offers some advantages over other dielectric materials. It has a low dielectric absorption and dissipation factor, good capacitance retention at high temperatures and good resistive characteristics. It also provides excellent ESR performance, and the ability to handle high ripple currents. Higher capacitance values can also be achieved with this dielectric.

The TAJD685M050RNJ is an excellent capacitor for many different applications due to its small size, low cost, and low leakage current. It is also capable of handling high ripple currents, as well as excellent capacitance retention at elevated temperatures. In addition, its low ESR, excellent reliability, and compliance with military standards make it an excellent choice for many different electronic applications.
