The resistors are lead (Pb)-free and the
pure tin plating provides compatibility with lead (Pb)-free and
lead-containing soldering processes. The immunity of the plating against
tin whisker growth has been proven under extensive testing, and all
products comply with the CEFIC-EECA-EICTA list of legal restrictions on
hazardous substances.
Products fully comply with the following
directives:
- 2000/53/EC
End of Vehicle Life Directive (ELV)
- 2000/53/EC
Annex II to End of Vehicle Life Directive (ELV II)
- 2002/95/EC
Restriction of the use of Hazardous Substances Directive (RoHS)
- 2002/96/EC
Waste Electrical and Electronic Equipment Directive (WEEE)
The Perspective:
Combining close tolerance and low thermal coefficient performance, Vishay
Beyschlag's new RoHS-compliant precision resistors in 0612 outline with
convex termination offer an accurate, cost-effective solution for the
development of designs with limited board space where high repeatability
and stable performance are required.
Availability:
Samples are available now. Lead time for production quantities is
6 to 8 weeks.
