Electromagnetics and Toroids

The Standard Handbook for Electrical Engineers defines a toroid coil as a simple, uniform magnetic circuit that creates confined magnetic fields within the core. Read More

Toroids and Modern Technology

Usually, the transformer is the largest component found in a circuit. Transformers are typically larger because the size is proportional to the square root of the total transformer power. Utilizing toroids is a good idea when working with transformers.Read More

Benefits of Winding

Toroid Coils are a closed-loop core. Toroid Coils have many benefits over other shaped cores. Many of the benefits are due to the winding aspect. Toroid core winding provides excellent benefits that make them ideal.Read More

Ferrite Cores and Applications

Ferrite cores are an oxide created with Iron, Manganese, and Zinc. Ferrite Cores are commonly referred to as manganese zinc ferrites. Due to their low losses at high frequencies, ferrite cores are regularly used in switched-mode power supply and radio frequency.Read More

Ferrite Core FAQ

Question: What is a ferrite core?
Answer: Ferrite cores are dense, homogeneous ceramic structures. They are made by mixing iron oxide with one or more metal such as manganese, zinc, nickel, or magnesium. Ferrites have high electrical resistivity and low eddy current losses over a wide frequency range. The characteristics of ferrites make them ideal for use in applications such as high-frequency transformers and adjustable inductors. Ferrites come in many different types of materials.Read More

Powder Core FAQ

Question: What is a powder core?
Answer: A powder core is a distribution of air gap cores, and they have many incredible characteristics. Some of their qualities include high resistivity, low hysteresis and eddy current losses, and excellent inductance stability under both DC and AC conditions.Read More
