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
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
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.

Taking into account the need for high-requirement SRF value, we chose this large black magnetic ring for winding.
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.
The strict requirements of customers are also our driving force.
Our magnetic core materials and copper wire materials are purchased from famous domestic raw material manufacturers KDM and Pacific Copper Wire. The skilled craftsmanship and superior materials make Mingda’s products more quality assurance.
At the same time, our quality supervision is like the finishing touch, with careful inspection and testing before shipment, and safe and reliable packaging methods. The products we sell have won unanimous praise from customers in Korea and Japan!

5.5mH 10 A Common mode choke
Common mode choke
Magnetic ring common mode inductors are widely used in refrigerators, washing machines, cameras, small-size fluorescent lamps, tape recorders, color TVs, etc. Among our common products, magnetic ring common mode inductors mainly suppress AC line common mode choke The flow loop conducts noise. With it, we don’t have to worry about signal blocking and interference when using these electronic products.
Used in AC tuner, fax, power supply, etc. Similar to the first point, the common-mode inductor mainly serves to suppress some of the messy output of the common-mode choke, and to accurately transmit the signal to the signal terminal.
Some partners have very high requirements for the inductance of the inductor. At this time, it is recommended to use the magnetic ring common mode inductor. The higher the magnetic permeability, the lower the temperature that the inductor can withstand. At the same time, we can also reduce the number of windings of the inductor coil and use large-diameter copper wire. Choose the right core according to your needs.
