工字型电感的磁芯(铁氧体)中的Pb是否属于豁免项

我司工字型电感在来料的时候测试其磁芯Pb含量为16000ppm,我司供方回复此磁芯是满足豁免条款7C-I,即“含有铅的玻璃或陶瓷的电气和电子元件,介质陶瓷电容器除外。如:高压设备,或玻璃或陶瓷基复合材料”。磁芯是铁氧体属于电子陶瓷类。
磁芯的主要成份为:三氧化二铁占52%、氧化锌15%、氧化铜17%、氧化镍16%
请高手指点下该磁芯是否满足豁免项。

好吧,磁芯确实属陶瓷,但符合豁免的前提是这个铅在这个磁芯有重要的功能。
楼主至少需先了解这个铅的功能是什么,如果是杂质照退不误。

妹的,好久没上官网了,啥子都不懂了。
7c-I. Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound

Electronic components such as diodes, chip resistors, piezoelectric devices, etc. are permitted to contain glass or ceramic materials that contain lead.

Ceramic materials are used in a variety of electronic devices including capacitors, insulators, piezoelectrics, magnets and integrated circuit packages. Some of these ceramic materials contain lead, for example lead zirconate titanate and lead magnesium niobate. The specific chemical composition and manufacturing process of these materials determine their electrical parameters, such as dielectric constant and the dissipation that is essential for the functioning of the component in which they are used. Hence, lead used in the ceramic parts of electronic components in electrical and electronic equipment is exempt from these Regulations.
