HARD FERRITE MAGNETSHard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.Ferrite Magnets characteristicsMostly Used national standard - SJ285-77 permanent ferrite magnet standardChinese SJ/T0410-2000 Permanent Ferrite Manget StandardIn MMPA（0100-87) standardRing shape size(mm) D×d×HФ115×45×5～23 Ф200×86×5～27 Ф70×32×3～17 Ф115×43×5～23 Ф200×83×5～27 Ф70×30.5×3～17 Ф115×45×5～23 Ф200×86×5～27 Ф70×32×3～17 Ф115×57×5～23 Ф200×95×5～27 Ф70×56×3～17 Ф115×58.7×3～23Ф200×100×5～27 Ф70×40×3～17 （elliptical）Ф115×60×5～23 Ф200×110×5～27 Ф71×40×3～17 Ф115×67×5～23 Ф200×120×5～27 Ф71×30.5×3～17 Ф115×80×5～23 Ф206×88.9×5～30 Ф71×32×3～17 Ф121×45×5～24 Ф206×89×5～30 Ф72×30.5×3～16 Ф121×57×5～24 Ф206×118×5～30 Ф72×32×3～16 Ф121×60×5～24 Ф210×86×5～30 Ф72×38×3～16 Ф121×65×5～24 Ф210×118×5～30 Ф72×40×3～16NdFeBKnown as third generation of Rare Earth magnets, Neodymium Iron Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnet today. Since they are made from Neodymium, one of the most plentiful rare earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.NdFeB magnets are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (28 MGOe to 50 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering.A variety of coatings can be applied to the magnets' surface to overcome the principle drawback of neodymium-based magnets, their tendency to corrode easily.Grade Max.

i 铁氧体材料特性及不同规格有效参数10.3.1 国产铁氧体材料特性铁氧体的电阻率大约在106～1012μΩ·cm ，适用于几千到几百兆Hz 的频率之间。

对铁氧体软磁材料的主要要求是：初始磁导率μ 高，比损耗（单位体积或重量）小,磁导率随温度的变化要小等。

锰锌和镍锌铁氧体是常用的材料。

可用来制作滤波电感，高频功率变压器，谐振电感等。

铁氧体材料最高工作频率主要受损耗限制。

在一定的允许损耗下，频率提高，工作磁通密度相应减少，与提高频率来减少磁芯体积相矛盾。

一般建议的磁通密度是在工作频率下权衡损耗、体积、结构和效率的结果，不是绝对的。

例如PHILIPS 建议变压器磁芯：<100kHz 可用3C81、3C90、3C91、3C94 和3C96 等；<400kHz 可用3C90、3C94 和3C96 等；200kHz ～1MHz 可用3F3、3F4 和3F35；1~3MHz 可用3F4 和4F1；>3MHz 可用4F1 等。

电感磁芯：<500kHz 可用2P…、3C30 和3C90;<1MHz 可用3C90、3F3 和3F35 等等。

国产常用的牌号及主要磁性能见表10-7所示。

10.3.2 铁氧体尺寸规格铁氧体磁芯在通讯和开关电源中应用十分广泛，磁芯外形结构多种多样。

开关电源中主要应用的有E 型，ETD 型，EC 型，RM 型，PQ 型，EFD 型，EI 型，EFD 型，环形，LP 型.在模块电源中，主要应用扁平磁芯和集成磁元件。

例如FERROXCUBE-PHILIPS 的平面E 型磁芯，适于表面贴装的EP 、EQ 和ER 磁芯，以及集成电感元件（IIC －Integrated inductance component ）等。

IIC 已将元件和磁芯合成一体，通过外部PCB 可自由组成电感和变压器。

各种磁芯结构往往是针对特定的应用设计的，有各自的优点和缺点，要根据应用场合，选择相应的磁芯结构。
