Silicon Steel Instrument Transformer Cores Custom Tape Wound Cores

Tape wound cores are a type of magnetic core used primarily in transformers and inductors. They are made by winding a tape of magnetic material, usually a ferromagnetic substance like ferrite or silicon steel, into a cylindrical shape. Here's a quick overview of why and how they are used:

Why Use Tape Wound Cores?

Reduced Core Losses: The tape-winding process can reduce core losses, especially hysteresis and eddy current losses, compared to other core shapes and materials.

High Frequency Performance: They are particularly good for high-frequency applications due to their low core loss and good magnetic permeability.

Improved Magnetic Properties: The tape winding technique can help in achieving a more uniform magnetic field and reducing core saturation issues.

Customization: The winding process allows for a variety of core shapes and sizes, making it versatile for different applications.

How They're Made

Material Preparation: A thin tape of magnetic material is prepared. This tape is usually coated with an insulating layer to prevent short circuits between turns.

Winding: The tape is wound around a mandrel or form to create a core. The winding can be done in various patterns to achieve desired magnetic properties.

Heat Treatment: The wound core may undergo heat treatment to improve its magnetic properties and relieve any stress in the material.

Applications

Transformers: Tape wound cores are often used in transformers for power supplies and other electronic devices where high efficiency is crucial.

Inductors: They are also used in inductors where low core loss and high inductance are required.

Filters: They can be used in filters for high-frequency signal processing.

In summary, tape wound cores are valued for their efficiency and performance in high-frequency and high-precision applications, thanks to their ability to minimize losses and optimize magnetic properties.
