Professional Leaded Resistors

MRS16, MRS25
Vishay BCcomponents
Professional Leaded Resistors
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.
Suitable replacements for MRS16 and MRS25 are
MBA/SMA 0204 and MBB/SMA 0207 professional.
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

12NC INFORMATION
• The resistors have a 12-digit numeric code starting with
232215.
• The subsequent 2digits indicate the resistor type and
packaging; seethe 12NC Ordering Code table.
• The remaining 4digits indicate the resistance value:
–The first 3digits indicate the resistance value.
–The last digit indicates the resistance decade in
accordance with the 12NC Indicating Resistance
Decade table.
Last Digit of 12NC Indicating Resistance Decade
12NC Example
The 12NC of a MRS16 resistor, value 750 Ω, on a bandolier
of 1000units in ammopack is: 232215717501.
