RoHS Compliance of Through-hole Components

On 1st of July 2005 KEKO VARICON will convert to lead-free production of through–hole components :

• disc/multilayer varistors (CV, CV+, SV, ZV, AV),
• disc/multilayer ceramic capacitors (KM, KZ, KV, CL) and
• dual function components (MV, OV)

and thereby fulfill all requirements of RoHS directives (2002/95/EC, 2003/11/EC).

►	Labeling Differentiation between non-Pb-free components and Pb-free ones will be made in the documents and on package units: in Order Confirmation – Pb-free components will be designated with ‘RoHS Compliant’ in Dispatch Note – Pb-free components will be designated with ‘RoHS Compliant’ on the package unit and outer boxes - Pb-free components will be designated with yellow adhesive tape with inscription ‘Pb-free’
►	Type designation KEKO VARICON will not change type designation of RoHS compliant types with respect to those which are not. Only labelling will be different as described below.
►	Pb-free Wave Soldering Profile Recommendations Recommended soldering profiles for all above components are in accordance with JEDEC standard curves (JES D22 – B106C) and therefore compatible with new 270 °C Pb-free process.
►	Resistance to Soldering Heat In order to prevent any potential problems KEKO VARICON decided to introduce its own internal standard for testing of resistance to soldering heat of through-hole components : 300 °C ,10 s.
