Tantalum capacitors, also known as solid electrolytic capacitors, are the most common type of capacitors, usually made of tantalum oxide of SnO or Ta2O5 and a variable amount of MnO2. The M39003/03-0463H multi-anode capacitor is a surface mountable, non-solid, non-conformal, and RoHS compliant capacitor manufactured by Eaton. It is a high-capacity, electrolytic capacitor designed for use in applications such as avionics and aerospace, medical devices, and industrial electronics. Its design allows for a wide range of capacitance and voltage ratings, and it is capable of providing reliable operation at elevated temperatures.

The M39003/03-0463H capacitor is composed of stacked anodes containing a total of four layers of tantalum. Each layer consists of a sheet of metal foil, dried tantalum powder, and silver-filled solder sealing the anodes together. The anode and cathode are covered with a non-corrosive, epoxy coating. The electrical properties of the capacitor are determined by the number of anodes and the amount of tantalum powder used in each layer.

The working principle of the M39003/03-0463H is based on the behavior of electrical currents in a capacitor. When a current is applied to the anode, the positive charges flow to the negatively-charged cathode, creating an electrostatic field. This electrostatic field gradually builds up and stores energy, creating an electric field or potential. As the current continues to flow, the charges gradually build up and eventually reach equilibrium, resulting in a steady-state current into the capacitor. This stored energy can be released when the circuit is disconnected.

The M39003/03-0463H is designed to provide superior voltage, current, and temperature (VCT) capabilities in a wide range of applications. It is well-suited for power supply and energy storage needs, as it is capable of withstanding temperatures up to up to 125°C. Its non-solid construction and RoHS compliance also make it an attractive option for safety-critical applications.

The M39003/03-0463H is a versatile capacitor capable of providing reliable operation in a variety of situations. Its four-layer construction gives it high capacitance and current ratings, making it suitable for use in applications such as medical devices, avionics, aerospace, and industrial electronics. Its design allows it to withstand high temperatures, making it ideal for harsh environments. Its non-silver construction and RoHS compliancemake it an attractive choice for safety-critical applications.
