1) Closer tolerances upon request.
2) Replace the + by code letter »A« for axial taping or by »B« for radial taping.
3) For Ammo pack the last digit has to be a »9«. Example: B82143A1102K009.

RoHS-compatible is defined as compatible with the follow-
ing documents:
DIRECTIVE 2002/95/EC OF THE EUROPEAN PARLIA-
MENT AND OF THE COUNCIL of 13 February 2003 on the
restriction of the use of certain hazardous substances in
electrical and electronic equipment COM (2004) 606 final
Proposal for a COUNCIL DECISION amending Directive
2002/95/EC of the European Parliament and of the Council
for the purposes of establishing the maximum concentra-
tion values for certain hazardous substances in electrical
and electronic equipment.
When bending the leads, take care that the start-of-winding
areas at the face ends (protected by glue and
lacquer) are not subjected to any mechanical stress.
