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 Southern Electronic Element Factory Co.,Ltd now is in the course of developing into the Southern Group,The company now possess all kinds of professional technicians of over a hundred.It occupies an area of 50,000 Square Meter,and the area of structure is 30,000 Square Meter.
The company mainly produce Wire-wound Resistor, Wire-wound Fuse Resistor, Film-type Fuse Resistor, Fixed Inductor, Ferrite Transformer, Toroidal Coil, Special Fuse for Energy-Saving Lamps(CFL),UL fuse, Inverter Reactor, Filter ,etc.
I-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.
2 hollow inductance coil
Edit
(also known as bodiless coil or hollow coil, used for high-frequency circuits) without core, skeleton, and shield etc., but first in the mold around the good and then take off the mold and the coil ring between a certain distance.
Refers to a group of 2 winding coil has a set of function, it is the basic part of the i-inductor.
Winding has a single layer and a multi-layer of points. Single-layer windings and tightly wound (the winding wire circle next to a circle) and around the winding between each coil wires are separated a certain distance) in two forms; multilayer winding a multiple layered flat around, mess around, duolateral winding etc..
3. Magnetic core and magnetic core and magnetic bar commonly used nickel zinc ferrite (NX Series) or Mn Zn ferrite body (MX Series) and other materials, it has "workers" - shaped, cylindrical, and the shape of the cap, "e" shape, cylindrical, ring a variety of shapes.
4 core material mainly silicon steel, slope Mo alloy, etc., its shape is more E type.
5. The shielding cover to avoid some inductance coil in magnetic field to affect the normal work of the other circuits and components, the increased metal screen cover (for example of a semiconductor radio oscillation coil etc). The use of shielded inductor, will increase the loss of the coil, so that Q value is reduced.
