Tantalum capacitors consist of a tantalum oxide anode, a very thin oxide dielectric layer and a cathode. The anode and the cathode are connected in a closed circuit and the oxide dielectric layer is sandwiched in between the two contacts. The construction result in a unique capacitor with many beneficial properties.

The M39003/09-4042/TR capacitor is an ultra-stable axial leaded tantalum capacitor constructed for use in high power applications. This particular type of tantalum capacitor is designed to provide excellent performance due to its advanced, special cathode design. The cathode, made from a special molybdenum-rich cathode alloy, is especially designed to provide improved resistance to wear-out and better tolerance to ripple current. The M39003/09-4042/TR capacitor also has a high capacitance rating and low leakage current at high temperatures.

The M39003/09-4042/TR capacitor is ideal for use in high power applications with high-temperature and/or high-voltage requirements. Examples of such applications include high temperature/high voltage power supplies, medical or industrial instrumentation, and automotive applications. In particular, the M39003/09-4042/TR capacitor is ideal for use in electric cars, as it provides a high capacitance rating and low leakage current even at high temperatures. Because of its high stability, the M39003/09-4042/TR capacitor is also well-suited for use in temperature-sensitive systems, such as those used in precision motor controllers.

The working principle of a tantalum capacitor is similar to other types of capacitors. A charge is applied to the anode side, while the cathode side remains at a zero voltage. As electrons are drawn to the anode, the dielectric layer between the anode and cathode becomes charged and stores the charge, creating a capacitance. The stored energy then limits the voltage level that can be applied across the capacitor. When current is applied to the capacitor, the charges will flow through the capacitor, causing a current.

The M39003/09-4042/TR capacitor offers several advantages over other, more traditional capacitor types. The cathode contains a special molybdenum-rich alloy which increases the capacitor’s stability at high temperatures, allows for higher tolerance to ripple current, and reduces the chances of wear-out. Moreover, the M39003/09-4042/TR capacitor has a high capacitance rating with low leakage current at high temperatures. This makes it suitable for use in electric vehicles, as well as in temperature-sensitive systems.
