  What is RoHS? What is RoHS 2.0? What is RoHS 3.0?

  Directive 2011/65/EU was published in 2011 by the EU, which is known as RoHS-Recast or RoHS 2. RoHS 2 includes a CE-marking directive, with RoHS compliance now being required for CE marking of products. RoHS 2 also added Categories 8 and 9, and has additional compliance recordkeeping requirements.
  Directive 2015/863 is known as RoHS 3. RoHS 3 adds four additional restricted substances (phthalates) to the list of six.
  As now China's test lab does not have RoHS 3.0 test standard. So Topdiode and UF Capacitors only declare our products are RoHS 2.0 Compliant. We will update our certification according to latest regulations.
  RoHS Compliant for 2022
  Any business that sells applicable electrical or electronic products, equipment, sub-assemblies, cables, components, or spare parts directly to RoHS-directed countries, or sells to resellers, distributors or integrators that in turn sell products to these countries, is impacted if they utilize any of the restricted 10 substances.
  With the rapid spread of digitization, the world's production of electrical and electronic devices is exploding. Besides mobile devices, think about the coming wave of IoT, smart home assistants, robots, drones, 3D printers, and home medical devices to all corners of the planet...they are all regulated under RoHS.
  EU RoHS specifies maximum levels for the following 10 restricted substances. The first six applied to the original RoHS while the last four were added under RoHS 3, which took effect July 22, 2019.
  Cadmium (Cd): < 100 ppm
  Lead (Pb): < 1000 ppm
  Mercury (Hg): < 1000 ppm
  Hexavalent Chromium: (Cr VI) < 1000 ppm
  Polybrominated Biphenyls (PBB): < 1000 ppm
  Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
  Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
  Benzyl butyl phthalate (BBP): < 1000 ppm
  Dibutyl phthalate (DBP): < 1000 ppm
  Diisobutyl phthalate (DIBP): < 1000 ppm
  About Lead-Free and RoHS
  In practice, RoHS-compliant is often equated with “lead-free”. However, this is a widespread mistake. The RoHS directive 2002/95/EC aims to minimize the use of hazardous substances (including, among others, lead), but it does not completely exclude a small percentage. One of the great obstacles in implementing the directive was the switchover to lead-free solder, because the limit values (0.1 per cent by weight of the inseparable components) do not admit a lead solder. This is probably the most important reason for the mix-up/equating that comes up again and again.
  Due to environmental concerns, the need for lead-free solutions in electronic components and systems is receiving increasing attention within the semiconductor and electronics industries.
  In a word, Lead Free and Pb Free is the same thing. Due to worldwide environmental restricted chemical and material (RCM) concerns, it was determined lead (Pb) as one of the major substances of concerns. Lead-free devices in electronic components and systems continues to receive significant attention within the semiconductor and electronics industry as a whole.
  Lead Free and Pb Free mean "No PB Process". PB Free and Lead-Free electronics components are definitely RoHS Compliant. But RoHS Compliant did not mean Pb Free of Lead Free.
  RoHS Compliant means lead <1000 PPM, and also accept exemption sometimes.
  Ps: Green products mean stricter: Lead (Pb): < 90 ppm
  Topdiode & UF Capacitors’ all components are RoHS Compliant. But not all our electronic components are PB Free or Lead-Free. If you require Lead-Free, pls check case by case.
