Ferrocore LCBC-121 is a ferrite core material that contains nickel, zinc, and iron oxide in a ceramic matrix. It is designed for use in high frequency applications such as transformers, inductors, RF filters, and EMF shielding. The ferrite material has high permeability and low magnetic loss which makes it ideal for high frequency applications. Additionally, the material is temperature and frequency stable, making it suitable for operating over a wide range of temperatures and frequencies. It also has excellent rigidity, making it resistant to shock and vibration. The combination of these features makes LCBC-121 an ideal choice for applications requiring high performance, reliability, and repeatability.
