Wound coil, miniature coil GEM018- Fu Ying achieve three consecutive "0 Returns"

First, the structure and use of inductor: inductive coil is insulated wires (wire, yarn package line, wire, etc. ***) circle close a wound from the system diagram in an AC circuit, the coil hinder the AC current. by the action, and to a stable DC voltage but does not work (dc resistance line counts itself an exception). It can be used as choke coils, transformers, cross-linked, load, etc. In AC circuits. When mating is a coil and a capacitor can be used for tuning, filtering, frequency, frequency, decoupling and the like. Inductance coil, which is commonly used in anti-jamming electronic circuit components, high-frequency noise has a good shielding effect Second, the physical effect of the inductor coil: 1. inductor used in the circuit the letters "L" represents the inductance The unit is "Henry", referred to Henry, used the letters "H" represents; Hang units smaller than millihenrys, represented by the letters mH; the smaller unit is micro-henry, represented by the letters H. The relationship between them is: 1H = 103mH = 106uH (1) self-inductance and mutual inductance. When an alternating current through the inductor coil, the coil around the alternating magnetic field, the magnetic energy through the coil, and the induced electromotive force in the coil. Self-induced emf size and characteristics of the magnetic flux of the magnetic coil, this characteristic is represented by self inductance. Electric feeling. Feel the amount is the amount of electricity the numerical size of the inductor, commonly known as inductance. 2. The principle of self-inductance inductance coil: coil (inductance) in the direction of self-induced emf will be resistance to change the original magnetic field, it is because the original magnetic field is generated by the current in the coil, electric heat from feeling hampered by the coil The current changes, this impediment is the inductive reactance, which in ohms, inductance current sense of the size and the size of the coil inductor and through the exchange of relevant frequency, the greater the inductance, reactance he formed greater. Under the same inductance, higher frequency of the alternating current, inductance is greater. Their relationship may explain the following formula: L = 2fL where XL-- inductance; frequency f-- current; L - inductance. 3. The mutual inductor works: through the exchange of inductor alternating magnetic field, place another coil, an alternating magnetic field in the magnetic field lines passing through the coil, and an induced electromotive force in the coil, we will This phenomenon is called mutual inductance. Usually the original primary coil wire called mutual inductance is related to the beginning of the interaction between the secondary coil called a coupler (factor). Coupling coefficient and position the two coils of the way, with or without cores and other factors. Two coils are inductance and coupling coefficient between the two coils is related to the principle of mutual inductance of the coil is the common principle of a transformer.
