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. At times, the rapid advance of demand surpassed our capabilities. The race to develop new materials intensified during these times, when every competitor was working hard to catch up to and surpass all the others. At other times, we virtu- ally worked around the clock to develop new characteristics to support the technological objectives of our customers. 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 to make ferrite materials commer- cially available to the industrial world have been the driving force behind our efforts. Our rapid and unerring response to changing needs, as well as our aggressive involvement in the development of new markets, is the essence of our over 40 years of history in the field of fer- rite magnet development. The fruits of our technological development and the unique expertise we have gained in this process are shared among the relevant divi- sions within the company. Powder control technology is an excellent example. Our reserch & development provide many uniquely devel- oped concepts such as composite control technology, high dispersion technology, structural analysis and composite analysis technology, and high-precision molding. The results of their work, including such recent achievements as microscopic crystalline structures and very- large-scale production systems, are circulated, exchanged, and honed by the various divisions. Our "comprehensive strengths" give us the ability to produce accurate records of performance and data if requested. The products of our "comprehensive strengths"— which have evolved in a competitive environment fostered by these technological exchanges — include a wide range of ferrite and ceramic appli- cations as well as rare earth and composite magnets, all of which have gained excellent reputations in a broad range of technological fields. The innovative nature of TDK ferrite magnets is supported by our wide ranging expertise, the fruits of our latest research efforts attained by our technological pursuits, and the accumulation of various capabilities based on a diverse range of perspectives. We must have the capability to select the optimal material for a particular design objective for applied products, to design the optimal shape for improving the efficiency of a magnetic circuit, and to improve existing materials or begin the development of new materials to deliver the magnetic characteristics required by our customers. We must also have a development system that is flexible enough and is capable of responding quickly enough to support our customers in their efforts to reduce product development times. In addition to our development and manufacturing technologies, we must have a production management and distribution service system capable of quickly delivering ordered materials of different shapes in the proper quantity to ensure that we continue to be a trusted supplier to our customers. TDK currently operates five plants dedicated to ferrite magnet production in Japan and overseas. We have established an "in-market" ser- vice system for responding quickly to orders and requests for technical services when customers contact one of our production or service offices. In addition to delivering high-quality magnets with excellent characteristics, we also actively support our customers efforts to reduce design time and to optimize their designs based on our abundant expertise in the filed of magnetic circuitry design. • Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

HIGH PERFORMANCE ANISOTROPIC MATERIALS FB12(WET-MOLDED), FB13B • FB14H(THIN-TYPE) AND FB5D(DRY-MOLDED) SERIES With new compositions and microstructures, these ferrite magnets deliver the best characteristics. FEATURES FB12 SERIES(FB12B, FB12H) This wet-molded anisotropic ferrite magnet has even greater superiority over the FB9 series and delivers the world's greatest magnetic force with an even further improved coercive force HCJ temperature coefficient. FB13B・FB14H SERIES These are thin-type anisotropic ferrite magnets with the world's greatest performance. These series have been developed by enabling thin molding and improving the orientation of FB12 series(Suitable thickness: 1.0 to 2.0mm). FB5D SERIES(FB5D, FB5DH) These dry-molded ferrite magnets deliver magnetic characteristics that rival wet-molded magnets. These magnets can be made into small and complex shapes that are difficult to make as wet-molded magnets. Their coercive force HCJ temperature coefficient is also superior. APPLICATIONS FB12 SERIES Electrical motors, actuators, appliance motors, medical equipment and other motors. FB13B • FB14H SERIES Small motors and actuators for electric components, motors and actuators for office automation equipment and medical equipment, various sensors, etc. FB5D SERIES Small motors for electric components, office computing and audio-visual equipment, household appliances and other motors.
