Ferrite Materials Offer High Stability, Low Loss

Described as high-stability, manganese-zinc ferrite core materials, the F58 and P11 materials cover a frequency range from 10 kHz to 1 MHz and promise low TCRs and a low loss factor, making them contenders for applications involving filter networks, proximity switches, and gate drive transformers for switchmode power supplies. The F58 material specifies a frequency range of 200 kHz to 1 MHz and an initial permeability of 750 at 10 kHz and 25ºC. With a frequency range from 10 kHz to 500 kHz, the P11 material features an initial permeability of 2,250 at 10 kHz and 25ºC. Both materials are available in standard RM and pot core geometries, while the F58 material is also available in torroidal-core configurations. Other shapes are available upon request.
