A capacitor consists of two metal plates and an insulating material known as a dielectric. Depending on the type of dielectric material and the construction, various types of capacitors are available in the market. Note: Capacitors differ in size and characteristics.
Electrolytic capacitors are normally made from one of three different materials: aluminum, tantalum, and niobium. Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons:
What are different types of metallization used in capacitor films? Metallized capacitor films have a thin coating of metal (commonly aluminium and zinc) deposited on them by vacuum deposition process. Several types and patterns are available to choose for metallization, depending on application and usage environment.
Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons: - Aluminum acts as a so-called “valve” metal, where a positive voltage in an electrolytic bath allows it to form a thin oxide layer that acts as a dielectric. -The aluminum anode is made from pure aluminum foil, which can form many capacitive layers.
Depending on the type of metal and electrolyte used, the electrolytic capacitors are classified into the following types. Aluminum electrolytic capacitors – aluminum oxide (dielectric). Tantalum electrolytic capacitors – tantalum pentoxide (dielectric). Niobium electrolytic capacitors – niobium pentoxide (dielectric). Aluminum electrolytic
The plastic films used as the dielectric for film capacitors are polypropylene (PP), polyester (PET), polyphenylene sulfide (PPS), polyethylene naphthalate (PEN), and polytetrafluoroethylene (PTFE). Polypropylene has a market share of about 50% and polyester with about 40% are the most used film materials.
