    Product introduction

    1. Inductance XL

     

    The size of the inductive coil's blocking effect on communication current is called inductance XL, and the unit is ohm. Its relationship with inductance L and communication frequency F is XL=2πfL.

     

    2. Quality factor Q

     

    The quality factor Q is a physical quantity indicating the coil quality, and Q is the ratio of inductive reactance XL to its equivalent resistance, that is, Q = XL/R.. The higher the q value of the coil, the smaller the loss of the loop. The q value of the coil is related to the DC resistance of the conductor, the dielectric loss of the skeleton, the loss caused by the shield or iron core, the influence of high frequency skin effect and other factors. The q value of the coil is generally tens to hundreds.

     

    3. Distributed capacitance

     

    The capacitance between turns of the coil, between the coil and the shield, and between the coil and the bottom plate is called distributed capacitance. The existence of distributed capacitance reduces the Q value of the coil and deteriorates its stability, so the smaller the distributed capacitance of the coil, the better.

     

    1. Single layer coil

     

    Single-layer coil is wound around paper tube or bakelite skeleton with insulated wires one by one. Such as a wave antenna coil in a transistor radio.

     

    2. Honeycomb coil

     

    If the plane of the wound coil is not parallel to the rotating surface, but intersects with a certain viewpoint, this kind of coil is called honeycomb coil. And the number of times the wire bends back and forth when it rotates once, which is often called the number of folding points. The advantages of honeycomb winding method are small volume, small distributed capacitance and large inductance. Honeycomb coils are all wound by honeycomb winding machine. The more folding points, the smaller the distributed capacitance.

     

    3. Ferrite core and iron powder core coil

     

    The inductance of the coil is related to whether there is a magnetic core or not. Penetrating ferrite core into hollow coil can increase inductance and improve the quality of coil.

     

    4, copper core coil

     

    Copper core coil is widely used in ultrashort wave scale. It is convenient and practical to change the inductance by rotating the orientation of copper core in the coil.

     

    5, color code inductor

     

    Color-coded inductor is an inductor with a fixed inductance, and its inductance is marked in the same way as that of resistance, with color ring as the symbol.

     

    6, choke coil (choke)

     

    The coil that restricts the passage of electricity is called choke coil, which can be divided into high frequency choke coil and low frequency choke coil.

     

    7. Deflection coil

     

    Deflection coil is the load of the output stage of TV scanning circuit. Deflection coil requires high deflection sensitivity, uniform magnetic field, high Q value, small size and low price. The basic unit of knitted fabric is curved in space, consisting of two circular columns, a knitting arc and a sinking arc (or extension line).
