Tantalum capacitors are solid electrolytic capacitors formed by the sandwiching between two conductive layers of a thin tantalum oxide film, which acts as dielectric, and a porous anode, which is made of tantalum nitride or other tantalum derivatives. The most common type of tantalum capacitor is the M39003/01-7284/HSD, which is designed for high reliability and application in various military and aerospace systems.

The M39003/01-7284/HSD is mainly used in power supplies where high power density and high reliability are needed. This type of capacitor is particularly suited for applications in aerospace and military equipment, where its high capacitance combined with its small size and high-temperature operation make it an ideal choice. The M39003/01-7284/HSD has a voltage rating of 160V and a capacitance of 1 farad.

The construction of the M39003/01-7284/HSD is such that the tantalum oxide layer between the anode and cathode of the capacitor acts as a dielectric and provides a strong electrical insulation between them. The anode of the capacitor is formed by sintering a porous tantalum powder which is then coated with a conductive paste, while the cathode is formed from a thin layer of tantalum oxide which is deposited onto a tantalum nitride substrate.

The working principle of the M39003/01-7284/HSD capacitor is based on the principle of electrochemical polarization. The electrical charge on the anode of the capacitor induces an ionic charge flow across the dielectric layer, which results in the creation of an electrical field. This electric field between the two electrodes and the dielectric is responsible for the capacitance of the device.

The M39003/01-7284/HSD is also designed to withstand high temperature operation. This is achieved by using an anode made of high temperature tolerant materials such as cryogenic grade tantalum powder, and an additional coating of tantalum oxide on the dielectric layer. This ensures that the device can operate at temperatures up to 175C without sacrificing its reliability.

The M39003/01-7284/HSD is a highly reliable device, with low equivalent series resistance (ESR) and low tolerance. Additionally, its small size and high capacitance makes it a suitable choice for many applications in the military and aerospace industries. The robust construction and high-temperature operation makes it the ideal choice for high reliability and high power density applications in the most demanding environments.
