Discover the Advantages of the Military Grade Capacitors

2024-09-22

We are excited to share with you the exceptional benefits of the military grade capacitors, designed to meet the rigorous demands of defense and aerospace applications. the capacitors are engineered to provide unparalleled reliability and performance in the most challenging environments, ensuring that your systems operate flawlessly under pressure.

One of the standout features of the military grade capacitors is their robust construction, which adheres to stringent military specifications. This ensures that they can withstand extreme temperatures, humidity, and mechanical stress, making them ideal for use in critical applications where failure is not an option. the capacitors are also designed to offer high capacitance values while maintaining a compact form factor, allowing for efficient use of space in your designs.

In addition to their durability, the military grade capacitors exhibit excellent electrical performance. They feature low equivalent series resistance (ESR) and high ripple current ratings, which contribute to improved efficiency and longevity in power supply circuits. This performance is crucial for applications such as radar systems, communication devices, and missile guidance systems, where precision and reliability are paramount.

The basic of TANTALUM CAPACITOR Technology

Most metals form crystalline oxides which are non-protecting, such as rust on iron or black oxide on copper. A few metals form dense, stable, tightly adhering, electrically insulating oxides. These are the so-called valve metals and include titanium, zirconium, niobium, tantalum, hafnium, and aluminum. Only a few of these permit the accurate control of oxide thickness by electrochemical means. Of these, the most valuable for the electronics industry are aluminum and tantalum.

Wet tantalum capacitors are basic to all kinds of electrical equipment from satellites, aerospace, airborne, military ground support, oil exploration, and power supplies. Their function is to store an electrical charge for later use. Capacitors consist of two conducting surfaces, usually metal plates, whose function is to conduct electricity. An insulating material or dielectric separates them. The dielectric used in all tantalum electrolytic capacitors is tantalum pentoxide.

Tantalum pentoxide compound possesses high dielectric strength and a high dielectric constant. As capacitors are being manufactured, a film of tantalum pentoxide is applied to their electrodes by means of an electronic process. The film is applied in various thicknesses and at various voltages and although transparent to begin with, it takes on different colors as light refracts through it. This coloring occurs on the tantalum electrodes of all types of tantalum capacitors. Rating for rating, tantalum capacitors tend to have as much as three times better capacitance / volume efficiency than aluminum electrolytic capacitors.

In the tantalum electrolytic capacitor, the distance between the plates is very small since it is only the thickness of the tantalum pentoxide film. As the dielectric constant of the tantalum pentoxide is high, the capacitance of a tantalum capacitor is high if the area of the plates is large。

The progress to produce Wet Electrolyte Tantalum Capacitors

Wet electrolyte, sintered anode tantalum capacitors often called wet slug tantalum capacitors, use a pellet of sintered tantalum power to which a lead has been attached. Tantalum powder of suitable fineness, sometimes mixed with binding agents, is mechanically pressed into pellets.

The lead is embedded during pressing of the pellet. The next step is a sintering operation in which binders, impurities and contaminants are vaporized and the tantalum particles are sintered into a porous mass with a very large surface area.

A film of tantalum pentoxide is electrochemically formed on the surface areas of the fused tantalum particles. Provided sufficient time and current is available, the oxide will grow to a thickness determined by the applied voltage.

The pellet is then inserted into a tantalum or silver can, which contains an electrolyte solution, A suitable end seal arrangement prevents the loss of the electrolyte. Wet slug tantalum capacitors are manufactured in a voltage range up to 125 VDC.
