Parts with the suffix ‘LF’ on the part number are fully compliant with the
European Union directive 2002/95/EC on the restriction of the use of certain
hazardous substances in electrical and electronic equipment. Note the RoHS
compliant parts are suitable for assembly using both Lead-free solders (see
Lead-free Reflow soldering profile) and Tin / Lead solders (see Tin / Lead Reflow
soldering profile).
