Universal coils are a common component in electronic products. It is mainly used for the magnetic field between isolation coils and magnetic materials to avoid interference or affecting the normal work of the device.

1. Function: The main role of universal coil is the magnetic field between isolation coils and magnetic materials. It can effectively reduce the magnetic field transmission and interdependence effects, and reduce interference and coupling between adjacent coils. This can improve the performance and stability of the equipment.

2. Materials: The universal coil is made of non -magnetic materials with high magnetic guidance rates, such as copper, aluminum, cast iron, graphite, etc. These materials have good conductivity and magnetic conductivity, and can effectively separate magnetic fields.

3. Structure: The structure of universal coils is diverse, and the common forms of ring, sheet, columnar are common. Different shapes and sizes are suitable for different equipment and coils. The structural design of the universal coil section magnetic film should take into account the isolation effect of the magnetic field and the diffusion of heat.

4. Application: GM coils are widely used in various electronic devices, such as electrocatators, transformers, coil soundtakes, motors, etc. They play an important role in isolating magnetic fields, improving performance and stability in electronic devices.

5. Precautions for buying: Selecting suitable universal coil magnetic movies need to consider multiple factors, including the conductivity, magnetic conductivity of the material, the size, shape and installation method of the magnetic film. In addition, according to the actual application needs, consider factors such as temperature, power, and frequency, and select the appropriate magnetic septum.
