Tantalum Capacitors

Tantalum capacitors are the newest type of capacitors available in the market. The name comes from the fact that the material used in their construction is the metallic element, tantalum, which has the symbol Ta. The specific type of capacitor being discussed in this article is the M39003/01-8355 type.

The M39003/01-8355 type of tantalum capacitors has advantages over other types of capacitors due to its robust construction and its superior charge and discharge characteristics. These tantalum capacitors are particularly suited for use in electronic circuits operating at elevated temperatures and voltage levels. These tantalum capacitors have a long life expectancy and are relatively unaffected by temperature cycling. This makes the M39003/01-8355 type of tantalum capacitors ideal for use in military and aerospace applications.

The construction of the M39003/01-8355 type of tantalum capacitors consists of a metallic anode rod, a metal oxide film dielectric, a porous gas-diffusion cathode, an electrolyte of aqueous potassium hydroxide, and an outer casing. The anode rod is composed of the metal tantalum. The dielectric material is a polyester-imideing film which is deposited onto the anode rod and connected to the cathode. The cathode is composed of a porous sintered disk made of tantalum and sintering powder.

The working principle of the M39003/01-8355 type of tantalum capacitors works by charging the anode with electrons. This causes the anode to gain a positive charge. The electrons from the anode then repel electrons from the cathode which causes the cathode to gain a negative charge. These separate charges create an electric field which allows electric current to flow between the anode and the cathode. This is how an electrical capacitor is formed which can store and release energy when a current is passed through it.

The M39003/01-8355 type of tantalum capacitors can be used in many applications for a variety of reasons. The most common applications for this type of capacitor are in military and aerospace, telecommunications, computers, and power supplies. They are particularly well suited for use in applications that require a high temperature operating environment or operate at elevated voltages. This type of capacitor offers excellent electrical characteristics in terms of temperature cycling, life expectancy, reliability, and power dissipation.
