We offer a variety of sizes according to your needs! Introducing the "FL Series," which can be used even at high temperatures!
We would like to introduce our toroidal coils, the 'FL/FP/FS series'. The "FL series" is made from Fe-Si alloy and has a stable effective permeability of μ70. It has a high saturation magnetic flux density of 8000 Gauss, making it suitable for high current applications. The "FP series" is made from high-purity electrolytic iron powder, providing stable quality. The "FS series" has an effective permeability of μ110 and excels in high-frequency characteristics. 【Features of the FL Series】 ■ Superior DC superimposition characteristics compared to the FS series ■ Due to its toroidal shape, it has a small leakage magnetic field and reduced humming ■ Its high saturation magnetic flux density allows for miniaturization compared to ferrite chokes like E-type ■ With a Curie temperature of 600°C, it can be used even at high temperatures around 150°C ■ Lower cost compared to amorphous and permalloy materials *For more details, please refer to the PDF document or feel free to contact us.
