Tantalum capacitors are a type of electrolytic capacitor that utilizes the element tantalum as one of its electrodes, allowing for a relatively small physical size and a large capacitance for a given voltage rating. The M39006/22-0170H is a radial, molded, axial-lead, solid tantalum capacitor specifically designed for military electronics applications as well as consumer and industrial electronics applications. It has a capacitance of 1700uF at an operating voltage of 20VDC.

M39006/22-0170H Application Field and Working Principle

The M39006/22-0170H capacitor is mainly used in military electronic applications and general-purpose commercial applications that require a reliable power source with little to no variations in voltage. It’s particularly suitable in applications such as power supplies, filters, DC-DC converters, and other circuits where an electrolytic capacitor of this size is needed.

The M39006/22-0170H capacitor utilizes tantalum anode and cathode electrodes and a solid electrolyte as its core components. The capacitor’s anode electrode is formed out of a pure tantalum pellet that’s mechanically and electrolytically connected to its ends and inserted into the capacitor case while the cathode is formed out of an iron slurry, known as MnO2, which provides a stable and predictable behavior. The solid electrolyte, which is a mixture of organic acids and propylene carbonates, is then used to fill in the gap between anode and cathode and form a dielectric layer for the capacitor.

When the capacitor is in use, the anode and cathode electrodes are electrically connected in parallel. A voltage is then applied to the anode and the capacitor begins to charge. As the capacitor charges, a Faradaic reaction takes place and charges start to accumulate in the form of opposite charges (one on the anode and one on the cathode). When the applied voltage is removed, the accumulated charges cause a synchronized shift of electrons between the anode and cathode that result in a situation known as discharge. This action is then maintained by the capacitor’s dielectric layer, which ensures that the charge can’t escape from the capacitor and thus maintain the size of the capacitor’s capacitance.
