MRS16, MRS25
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
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.
The resistors are completely lead (Pb)-free, the pure tin
plating provides compatibility with lead (Pb)-free and
lead-containing soldering processes.
Suitable replacements for MRS16 and MRS25 are the
MBA 0204 and MBB 0207 professional.

12NC INFORMATION
•
The resistors have a 12-digit numeric code starting with
2322 15.
•
The subsequent 2 digits indicate the resistor type and
packaging; see the 12NC Ordering Code table.
•
The remaining 4 digits indicate the resistance value:
–
The first 3 digits indicate the resistance value.
– The last digit indicates the resistance decade in
accordance with the 12NC Indicating Resistance Decade
table.
