MRS16, MRS25
Vishay BCcomponents
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)
DESCRIPTION APPLICATIONS
A homogeneous film of metal alloy is deposited on a high
All general purpose applications
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
MBA/SMA 0204 and MBB/SMA 0207 professional.
