MRS16, MRS25
Vishay BCcomponents
Professional Thin Film Leaded Resistors
FEATURES
Technology: Metal film
Professional resistors in small outlines
Low noise
Lead (Pb)-free solder contacts
DESCRIPTION
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
Compatible to RoHS Directive 2002/95/EC
the resistive layer, tinned connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated

climatic protection. Four or five color code rings designate
the resistance value and tolerance according to IEC 60062.
Suitable replacements for MRS16 and MRS25 are
MBA/SMA 0204 and MBB/SMA 0207 professional.
