Ferrite Magnets FB Series INTRODUCTION From the development of the FB1A material grade in 1959, TDK’s history of developing ferrite magnets has reflected with the progress of magnet application technology. Our technology departments faced many challenges, starting with the integration of physical properties, and including our efforts to reduce manufacturing costs by rationalizing our production lines and optimizing our material procurement practices to improve every product’s performance to impart a "differentiating factor" for the applied product. Our pride and our passion as the first company...
