　　Capacitor classification has never been a unified and fixedforms, different people have different ways of capacitor, can be roughly divided into the following several are.
　　According to the classification of capacitor frequency: high frequency capacitance, low frequency capacitance.Classification: high voltage capacitor voltage, low capacitance.
　　According to the polarity classification: electrodelesscapacitor, a capacitor.
　　According to the structure of the capacitor can be divided into three categories: Fixed capacitors, variable capacitorsand capacitor.
　　According to the classification of media: electrolytic capacitors, ordinary capacitor, vacuum capacitors,aluminum electrolytic capacitor.
　　Make material according to the classification of capacitor:mica capacitors, metallized film capacitor, ceramic capacitor,paper capacitors, polyester capacitors, monolithic capacitors (capacitance), composite dielectric capacitor,organic thin film capacitors, glass glaze capacitors, tantalum capacitors, film capacitors, polypropylene capacitor,
　　Classification according to use and use: capacitor power capacitor, super capacitor, high-voltage capacitor, parallel plate capacitor, filter capacitor, semiconductor capacitance,dielectric, AC coupling capacitor, tunable capacitors, fixed capacitors, Fala capacitor, pulse electric capacity,protection capacitor.
　　Or in accordance with the capacitor electrolyteclassification: organic dielectric capacitor, inorganicdielectric capacitors, electrolytic capacitors and air dielectric capacitor.
　　There is the use of the environment: high frequency bypasscapacitor, low-frequency bypass, filtering, tuning, high coupling, low coupling, small capacitors.
　　In general the general electric parts classification isaccording to package devices of different classification.
　　Is mainly used in the industrial production are not the same,for example, in electronics, integrated circuit board used on the element is divided into plug-in (a hole, a corresponding element with the pin) and the patch (corresponding elementwith pad their), capacitance also divided into plug-incapacitors and chip capacitors, mainly due to their different purposes, SMD components for high integration of large-scale integrated circuit, which is convenient for saving space, the plug-in components for integrated circuit with low degree, to reduce the cost.
