The document discusses the RoHS2 directive, which restricts the use of six hazardous substances in electrical and electronic equipment. RoHS2 took effect in 2013 and requires manufacturers to CE-mark their products and provide a declaration of conformity. Data from SiliconExpert shows that 37% of active components were RoHS2 compliant as of 2014, with compliance increasing over time as older products were phased out. Product categories like passives and interconnects had higher compliance than others.
