Microcoils

Magnetic cores are typically made from materials such as iron, steel, or ferromagnetic alloys and are widely used in transformers, inductors, and electromagnets due to their ability to efficiently concentrate magnetic flux and enhance magnetic performance. They exhibit strong magnetic properties, including high magnetic permeability and saturation flux density.

Ferrite cores are composed of ceramic compounds made from iron oxide (Fe2O3) and other metal oxides, such as manganese, zinc, or nickel AND are commonly used in RF transformers, inductors, and high-frequency circuits due to their low electrical conductivity and high magnetic permeability at high frequencies. Despite their ceramic composition, ferrite materials exhibit strong magnetic properties and high magnetic permeability, especially at high frequencies.

Non-magnetic cores are made from materials that are not susceptible to magnetic fields, such as plastic, ceramic, or glass and are used in applications where magnetic interference must be minimized or where magnetic properties are not required, such as in high-voltage insulation, mechanical support, or structural components.
They are electrically insulating and do not exhibit any magnetic properties.

Polyimide tubes serve a dual purpose as both the core and the insulation for the micro coil. Micro coils wound on polyimide tubes find applications in various fields, including medical devices, aerospace systems, telecommunications, and consumer electronics. They are commonly used in sensors, actuators, transducers, and other miniature electronic components where compact size, high performance, and reliability are essential. The diameter, length, and thickness of the polyimide tube can be customized to meet specific design requirements. This allows for the creation of micro coils with precise dimensions and electrical characteristics tailored to the needs of the application.

Custom bobbins are precisely engineered structures made from materials such as plastic, ceramic, or metal. They are designed to provide a stable and uniform platform for winding the micro coils. They can be manufactured to specific dimensions, shapes, and configurations to meet the requirements of the application.
Custom bobbins provide insulation and protection for the micro coil windings, preventing electrical short circuits and mechanical damage. Additional insulation materials, such as varnish or epoxy resin, may be applied to further enhance the electrical insulation and mechanical strength of the coil.
