Mould case capacitors

What is a molded chip tantalum capacitor?

The pellet is next coated with graphite, followed by a layer of metallic silver, which provides a conductive surface between the pellet and the leadframe. Molded Chip tantalum capacitor encases the element in plastic resins, such as epoxy materials.

What is a red polymer capacitor?

red polymer capacitors have a low profi le. As a result of the electrical and form factor characteristics, they have applications in a variety of handheld electronic devices or other applications that require a low-profi le capacitor that w CITORSMAXIMIZE PERFORMANCE AND RELIABI

What is a tantalum capacitor?

Vishay Sprague has been a pioneer and leader in this field, producing a large variety of tantalum capacitor types for consumer, industrial, automotive, military, and aerospace electronic applications. Tantalum is not found in its pure state. Rather, it is commonly found in a number of oxide minerals, often in combination with Columbium ore.

How much voltage can a solid electrolyte capacitor withstand?

They will typically withstand up to about 10 % of the rated DC working voltage in a reverse direction. Also important are their good low temperature performance characteristics and freedom from corrosive electrolytes. Vishay Sprague patented the original solid electrolyte capacitors and was the first to market them in 1956.

How is tantalum pentoxide applied to a capacitor?

As capacitors are being manufactured, a film of tantalum pentoxide is applied to their electrodes by means of an electrolytic 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.

What is a layered polymer aluminum capacitor?

Layered polymer aluminum capacitors use conduc-tive polymer as the electrolyte and have an aluminum cathode (see Figure 1).
