  • Why are most of the products halogen-free?
    • Although we have been using molded resins containing brominated flame retardants that comply with the RoHS Directive, in order to further reduce environmental impact we will continue to adopt halogen-free resin.
      ROHM defines halogen-free as (in homogeneous material):
      1) Chlorine 900ppm or less
      2) Bromine 900ppm or less
      3) Total concentrations of chlorine and bromine 1500ppms or less
      4) Antimony trioxide 1000ppms or less
      These specifications comply with the requirements of IEC61249 and are intended to satisfy the stringent environmental management demands of European manufacturers.
