RoHS/Soldering: Parts with the suffix ‘LF’ on the part

num ber are fully com pliant with the European Union

directive 2002/95/EC on the restriction of the use of certain

hazardous substances in electrical and electronic

equipm ent.

Note:The RoHS com piant parts are suitable for

assem bly using both Lead-free solders (see Lead-free

Reflow soldering profile) and Tin/Lead solders (see Tin/Lead

Reflow soldering profile).
