HF Series High-Frequency Power Toroids

Fair-Rite’s manganese-zinc ferrites operate in SiC and GaN power supplies with stable temperature responses for 5 MHz designs

Image of Fair-Rite's HF Series High-Frequency Power ToroidsGaN, SiC, and other semiconductor technologies are pushing operating frequencies into the Megahertz range, fueling the need for high-frequency power materials with losses that do not cause issues with efficiency and heat management. Fair-Rite’s 79-material product line continues to expand and includes geometries for power supply designs. With operating frequencies up to 1 MHz, this material is optimized for minimal losses at elevated temperatures. Fair-Rite’s latest addition, the 80-material manganese-zinc ferrites, have been tuned to operate in SiC and GaN switching power supplies with a stable temperature response for designs up to 5 MHz.
