RC80H material is a soft magnetic ferrite material with high permeability (800±20%) and ultra-low loss (loss factor ≤13× 10-6/0.1MHz) developed by our company. At the same time, it has high working frequency and low residual flux density. The ratio of loss factor of RC80H material is lower than that of similar products in the same industry, and the product has strong competitiveness. This kind of material can be widely used in all kinds of high frequency broadband devices, such as: inductor, transformer, high frequency antenna, high frequency interference suppressor, etc.
