Changzhou Southern Electronic Element Factory Co.,Ltd is located in the city of Changzhou,which has a long history in Jiangsu Province.It is situated in the most active economic area in Yangtze River Delta Centre.The transport is very convenient. Expressway,Fast railways run though it.And it only takes one and half hours to reach Shanghai or Nanjing city.Airplane from here is through to major cities in China.
      Changzhou Southern Electronic Element Factory Co.,Ltd was founded in 1989.After several years' development and effort,it has invested and opened up three subsidiary companies,in Yancheng city, Huai'an city in Jiangsu Province ,and Lang'xi City in Anhui Province respectively. 
   

The structure of the Radial-inductor

Edit

An inductance coil consists of core or core, skeleton, winding, shield, packaging materials etc.:

1 Radial-inductor skeleton is composed of a copper core coil winding bracket. The inner cavity of the promotion means, one of the I-shaped inductance is an electronic circuit or device attributes is: when the current is changed, by electromagnetic induction and resistance current change of the electric potential volume of the larger fixed inductors or adjustable inductor (such as oscillation coil, choke coil, etc.), commonly used the I-shaped inductance is regarded as axial inductor vertical version, convenient application and axial inductor is similar, but the commonly used I-shaped inductance can have a larger volume of the inductor type, the current nature also can get a certain application; most of the enameled wire (or cotton covered wire is directly wound on the skeleton, a core or copper, iron into the skeleton to improve the inductance. The skeleton is usually made of plastic, bakelite, ceramics, can be made into different shapes according to actual needs. Small inductance coil (e.g. I-inductor) generally do not use the skeleton, but directly to the enameled wire wound on the magnetic core
