DESCRIPTION
MBA/SMA 0204, MBB/SMA 0207 and MBE/SMA 0414
professional leaded thin film resistors are the general
purpose resistor for all fields of professional electronics
where reliability and stability is of major concern. Typical
applications include industrial, telecommunication and
medical equipment.
FEATURES
•Available in standard version or CECC version
(approved according to EN 140101-806)
•Advanced thin film technology
•Power dissipation rating up to 1 W
•Excellent overall stability: Class 0.25
•Wide professional range: 0.22 Ω to 22 MΩ
•Lead (Pb)-free solder contacts
•Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
•Compliant to RoHS directive 2002/95/EC
•AEC-Q200 qualified available
APPLICATIONS
•Industrial
•Telecommunication
•Medical equipment
Notes
• MB_ series has been merged with the related SMA series to form one series “MB_/SMA__”
• These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over
operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

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.
Connecting wires of electrolytic copper plated with 100 %
pure tin are welded to the termination caps. The resistor
elements are covered by a light blue protective coating
designed for electrical, mechanical and climatic protection.
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 or for the radial versions in accordance to
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 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.
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.
All products comply with GADSL (1) and the
CEFIC-EECA-EICTA (2) 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 (CECC version) 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 the 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.

HISTORICAL 12NC INFORMATION
•The resistors had a 12-digit numeric code starting with
2312
•The subsequent 4 digits indicated the resistor type,
specification and packaging; see the 12NC table
•The remaining 4 digits indicated the resistance value:
- The first 3 digits indicated the resistance value
- The last digit indicated the resistance decade in
accordance with resistance decade table
Resistance Decade
Historical 12NC Example
The 12NC code of a MBA 0204 resistor, value 47.5 kΩ and
TCR 50 with ± 1 % tolerance, supplied on bandolier in a box
of 5000 units was: 2312 905 14753.
