Working Principle of M39003/01-2419/HSD

The M39003/01-2419/HSD is a solid-tantalum capacitor constructed with a two-piece design. This consists of a miniature tantalum anode surrounded by a dielectric oxide layer. This tantalum anode is then encapsulated in an epoxy resin. Attached to the lead frame of the capacitor is a small, metallized cathode film, which is the discharge system.

The operating principle of this capacitor is based on the voltage-controlled conduction of electrons. When a voltage is applied across the unit, the electrons flow freely within the oxide layer due to the electric field formed. As the voltage increases, the number of electrons increases and the capacitance decreases. When the voltage reaches a maximum value, the cathode film provides an additional discharge path, thus reducing the rate of current flow and preventing damage.

The M39003/01-2419/HSD tantalum capacitor is designed to be a long-term, reliable solution in extreme environments. Its two-piece construction and voltage-controlled conduction provide reliable operation in extreme temperature, vibration, and radiation conditions.
