Tantalum Capacitors

Properly designed and manufactured capacitor will usually provide reliable and accurate service. Tantalum capacitors are no exception. The M39003/01-2392/HSD resin-dipped capacitor is a miniature hybrid capacitor acting as both a DC block capacitor and a snubber capacitor in the application field. It is designed to be an ideal choice for many of the most demanding applications.

Application Field

The M39003/01-2392/HSD is used widely in military and aerospace applications, as well as avionics, high-frequency RF amplification, microwave, base station radios, pulse power circuits, mammography X-ray systems, medical equipment, satellite communication systems, power supplies, and other applications requiring high voltage, very low ESR, and very low leakage. Its combination of a maximum temperature range of -55°C to +125°C, and a capacitance range of 3.3 pF to 0.033 uF, makes it an ideal candidate for military/aerospace applications as well as commercial designs.

The M39003/01-2392/HSD capacitor is also a preferred choice for energy-intensive applications where high ripple currents are required. This is due to the design process that extends its operational life and a solid Tantalum-anode polymer hybrid allows for use in many critical applications.

Working Principle

Tantalum capacitors are electrolytic storage devices that encase the element tantalum with a dielectric oxide in ceramic that is formed on the element’s surface. The tantalum element forms the anode in the capacitor and the oxide layer is the cathode. The capacitors are hermetically sealed and, as such, rely on effective sealing to prevent corrosion and premature failure. These capacitors work on the principle of charging and discharging.

The M39003/01-2392/HSD capacitor consists of two conductors or plates, which are separated by a dielectric material instead of an insulator. When a voltage is applied across the two plates, the capacitor begins to store electrical energy. This electricity is stored in the form of an electric field between the plates. The M39003/01-2392/HSD capacitor produces a low ESR, usually below 0.30 Ohms, and a Low Leakage Current of 0.050 uA at 25°C.

The M39003/01-2392/HSD capacitor is a miniature hybrid, designed to offer the advantages of both an electrolytic and a module-dipped capacitor. It also offers the superior performance of a Tantalum anode with an electrolyte impregnated dielectric layer, and surface-mount technology. This combination gives the M39003/01-2392/HSD capacitor a long operational life in many of the most demanding applications.

The high performance characteristics of the M39003/01-2392/HSD capacitor make it an ideal choice when reliable and accurate operation is required. In addition to its low ESR and Low Leakage Current ratings, the capacitor also offers a high capacitance range, excellent operation across a wide temperature range and exceptional frequency performance. All these features, combined with its robust construction and small size, make an ideal choice for many challenging applications.
