Vishay BCcomponents
Lead (Pb)-Free Professional Leaded Resistors
FEATURES
• Professional resistors in small outlines
• Low noise.
• Lead (Pb)-free solder contacts
• Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compatible with “Restriction of the use of Hazardous
Substances” (RoHS) directive 2002/95/EC (issue 2004)
APPLICATIONS
• All general purpose applications.
DESCRIPTION
The resistors are completely lead (Pb)-free, the pure tin
plating provides compatibility with lead (Pb)-free and
lead-containing soldering processes.
A homogeneous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated
with lacquer which provides electrical, mechanical, and
climatic protection. Four or five colour code rings designate
the resistance value and tolerance according to IEC 60 062.
Suitable replacements for MRS16 and MRS25 are the
MBA 0204 and MBB 0207 professional.
