M39003/03-2014/HSD

Tantalum capacitors, also known as tantalum electrolytic capacitors, are used in electronic equipment. They are the most commonly used type of electrolytic capacitor. The construction of tantalum capacitors consists of a tantalum anode, an anode lead, an electrolyte, a dielectric layer, a cathode lead and ultimately, a cathode. They are usually much smaller than other electrolytic capacitors, so they are often used in medical and aerospace electronics, where space is at a premium.

The M39003/03-2014/HSD series allows surface mounting of tantalum capacitors in order to save valuable space. These capacitors are the most efficient and reliable capacitors for surface-mount technology. Thanks to their unique design, they offer superior volumetric efficiency, ripple current ratings and superior surge ratings for the most severe applications.

The application field of the M39003/03-2014/HSD series of tantalum capacitors is varied, and these capacitors are used for both low voltage and high voltage applications. They are used in telecommunications, automotive electronics, military/defense systems, medical systems and a wide range of consumer electronics. These capacitors can be found in high current application circuits, such as DC-DC converters and power supplies. They are also found in low current and high frequency applications such as cell phones and laptop computers.

The working principle of tantalum capacitors is straightforward. When a DC voltage is applied across the anode and the cathode of a tantalum capacitor, the anode lead and the cathode lead act as electrodes, creating an electric field. The electric field causes an exchange of ions between the anode and the cathode, forming a thin, insulating oxide layer on the anode. This oxide layer is the dielectric of the capacitor, and it stores electric energy. The capacitance of the capacitor is related to the distance between the anode and the cathode, the strength of the electric field, and the type and area of the plates.

The M39003/03-2014/HSD series of tantalum capacitors is highly reliable and offers superior performance in some of the most demanding environments and applications. Thanks to their unique design, their volumetric efficiency and ripple current ratings are among the highest on the market, and their superior surge ratings make them the perfect choice for the most severe applications.
