  • Color code inductor

    Color code inductor

    The color ring inductor is a reactive device. Inductors are often used in electronic circuits. A wire is placed on an iron core or an air-core coil is an inductor. When the current passes through a section of wire, a certain electromagnetic field will be generated around the wire, and this electromagnetic field will have an effect on the wire in this electromagnetic field. We call this effect electromagnetic induction. In order to strengthen electromagnetic induction, people often wind an insulated wire into a coil with a certain number of turns, and we call this coil an inductance coil. For simple identification, the inductance coil is usually called an inductor or an inductor.

  • Booster tripod transformer

    Booster tripod transformer

    Tripod inductor, also known as autotransformer, is a transformer with only one winding. When it is used as step-down transformer, a part of the wire turns are drawn out from the winding as the secondary winding; when it is used as step-up transformer, the applied voltage is only applied to a part of the wire turns of the winding. Generally, the primary and secondary windings are called common windings, and the rest are called series windings. Compared with ordinary transformers, the autotransformer with the same capacity has smaller size and higher efficiency, and the larger the capacity of the transformer, the higher the voltage. This advantage is more prominent.

    Inductance value range: 1.0uH ~1H

  • Sendust ferrite core

    Sendust ferrite core

    Near zero magnetostriction makes Sendust cores ideal for eliminating audible noise in filter inductors, core loss of sendust cores are significantly than those of powdered iron cores, Especially sendust E shapes provide a higher energy storage capacity than gapped. Finished sendust cores are coated in a black epoxy.

  • Ferrite core

    Ferrite core

    Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium. They are pressed, then fired in a kiln at 1,000 – 1,500°C and machined as needed to meet various operational requirements. Ferrite parts can be easily and economically molded into many different geometries. A diverse set of materials, providing a range of desired electrical and mechanical properties, are available from Magnetics.

    In the field of magnetic toroidal inductors, small magnetic toroidal inductors have great demand in the market. On the contrary, there are few large magnetic loop inductors, which is based on technical difficulty and cost issues.

    Mature technology is the self-confidence of the factory.

    In our factory, the skilled workers have more than ten years of technical experience. In the production of these different types of magnetic loop inductors, the workers’ time and technology are in place in one step, which largely solves the problem of production efficiency.

    To design this three “high” product, we have passed many tests and determined the final competent solution through material selection and production methods.
