POCO is specialized in the development, manufacture and sale of magnetic powder cores. We emphasize quality and services. We have advanced PHD cores (amorphous, fesi gaps), which is mainly used for inverters for Solar,Wind power.NPF (high flux), which is mainly used for choke, in-line noise filters and inductors.PPF (fesi cores),which is mainly used for reactors for new power and inductorsNPS (sendust cores), PPM (Nano fesi cores) and PPI (iron powder cores). They are mainly used for Inductors, Filters, Transformers and inverters.After years of development, POCO has grown into a professional metal solf magnet manufacturer.
