Notes
(1) Resistance values to be selected from E96 and E192 series, for other values please contact factory
Resistance ranges printed in bold are preferred TCR/tolerance combinations with optimized availability
DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a high grade
ceramic body and conditioned to achieve the desired
temperature coefficient. Plated steel termination caps are
firmly pressed on the metallized rods. A special laser is used
to achieve the target value by smoothly cutting a helical
groove in the resistive layer without damaging the ceramics.
A further conditioning is applied in order to stabilise the
trimming result. Connecting wires of electrolytic copper
plated with 100 pure tin are welded to the termination caps.
The resistors are covered by protective coating designed for
electrical, mechanical and climatic protection.The
terminations receive a final pure tin on nickel plating. Four or
five color code rings designate the resistance value and
tolerance in accordance with IEC 60062.
The result of the determined production is verified by an
extensive testing procedure performed on 100 of the
individual resistors. Only accepted products are stuck
directly on the adhesive tapes in accordance with
IEC 60286-1; IEC 60286-2.
ASSEMBLY
The resistors are suitable for processing on automatic
insertion equipment and cutting and bending machines.
Excellent solderability is proven, even after extended
storage. They are suitable for automatic soldering using
wave or dipping. The encapsulation is resistant to all
cleaning solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
suitability of conformal coatings, if applied, shall be qualified
by appropriate means to ensure the long-term stability of the
whole system. The resistors are completely lead (Pb)-free,
the pure tin plating provides compatibility with lead (Pb)-free
and lead-containing soldering processes. The immunity of
the plating against tin whisker growth has been proven under
extensive testing. All products comply with GADSL (2) and
the CEFIC-EECA-EICTA (3) list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
2000/53/EC End of Vehicle Life Directive (ELV) and
Annex II (ELVII)
2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
2002/96/EC Waste Electrical and Electrical Equipment
Directive (WEEE)
APPROVALS
The resistors are approved within the IECQ-CECC Quality
Assessment System for Electronic Components to the detail
specification EN 140101-806 which refers to EN 60115-1
and EN 140100 and the variety of environmental test
procedures of the IEC 60068 series. Conformity is attested
by the use of the CECC logo ( ) as the Mark of Conformity
on the package label for CECC version.
Vishay BEYSCHLAG has achieved “Approval of
Manufacturer” in accordance with IEC QC 001002-3,
clause 2. The release certificate for “Technology Approval
Schedule” in accordance with CECC 240001 based on
IEC QC 001002-3, clause 6 is granted for the Vishay
BEYSCHLAG manufacturing process.

12NC INFORMATION FOR HISTORICAL CODING REFERENCE
The resistors have a 12-digit numeric code starting with
2312
The subsequent 4 digits indicate the resistor type,
specification and packaging; see the 12NC 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 resistance decade table shown below
Last Digit of 12NC Indicating Resistance Decade
12NC Example (For Historical coding reference of
MBA 0204/MBB 0207/MBE 0414)
The 12NC code of a MBA 0204 resistor, value 47 kΩ and
TCR 25 with ± 0.1 % tolerance, supplied on bandolier in a
box of 5000 units is: 2312 906 74703.
