Tantalum capacitors are a subcategory of electrolytic capacitors, which are consist of two electrodes separated by an electrolyte, a conductive liquid. Tantalum capacitors are valuable components used in a wide variety of electronics, such as portable devices, computers and automotive systems. The M39003/01-5539 is a widely used tantalum capacitor, which is designed for use in military, industrial and space applications. In this article, we’ll discuss the applications and working principle of the M39003/01-5539.

Applications

The M39003/01-5539 is an axial leaded anode-away tantalum capacitor with conformal coating. Its operating temperature range is -55°C to 125°C and its dissipation factor is low. It is composed of tantalum and an electrolytic dielectric. The M39003/01-5539 is available with capacitance values ranging from 1µF to 2000µF and voltage ratings from 4V to 85V. The terminal lead material is Tin-Lead and its size ranges from 2.5mm to 15mm diameter.

The M39003/01-5539 is designed for applications where size and reliability are critical, such as military airborne or shipboard use. It is ideal for high-temperature or altitudes greater than 25,000 feet (7,620 m), and its ability to maintain stability under varying environmental conditions makes it an ideal choice for use in spacecraft and satellites.

The M39003/01-5539 is also suitable for use in a variety of different automotive applications. It is used in engine controls, sensors, and circuit boards for airbag systems. Additionally, it is used in start/stop systems, active chassis control systems, and electric power steering systems.

Working Principle

The M39003/01-5539 is a surface-mount tantalum capacitor. It is composed of a sintered tantalum anode, a liquid electrolyte cathode, and an oxide film dielectric. The pin-formation and anode are on opposite sides of the capacitor’s body.

The anode is made from the element tantalum and is formed into a spherical or cylindrical shape. A dielectric film is formed on the surface of the anode and acts as insulation. When the two electrodes are connected, electric charges flow from one electrode to the other. The capacitance of the capacitor is determined by the surface area of the anode and the thickness of the dielectric film.

The M39003/01-5539 operates on the same principle as other tantalum capacitors, but it also has special features to improve its performance and reliability. The capacitor is filled with an electrolyte, which serves as a spacer for electrons. This allows the capacitor to remain stable at low temperatures and under varying environmental conditions. The capacitor’s terminal leads are also solderable to minimize spiking and ensure electrical contact.

The M39003/01-5539 is an ideal choice for applications where size and reliability are critical. Its performance in extreme temperatures and altitudes makes it well-suited for use in military, industrial, and space applications.
