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. Alternative 
termination wires available e.g. weldable wire (MBA/SMA 
0204 only). 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.
MATERIALS
Vishay acknowledges the following systems for the 
regulation of hazardous substances:
• IEC 62474, Material Declaration for Products of and for the 
Electrotechnical Industry, with the list of declarable 
substances given therein 
(1)
• The Global Automotive Declarable Substance List 
(GADSL) 
(2)
• The REACH regulation (1907/2006/EC) and the related list 
of substances with very high concern (SVHC) 
(3)
 for its 
supply chain
The products do not contain any of the banned substances 
as per IEC 62474, GADSL, or the SVHC list, see 
www.vishay.com/how/leadfree
.
Hence the products fully comply with the following 
directives:
• 2000/53/EC End-of-Life Vehicle Directive (ELV) and 
Annex II (ELV II)
• 2011/65/EU Restriction of the Use of Hazardous 
Substances Directive (RoHS) with amendment 
2015/863/EU
• 2012/19/EU Waste Electrical and Electronic Equipment 
Directive (WEEE)
Vishay pursues the elimination of conflict minerals from its 
supply chain, see the Conflict Minerals Policy at

.
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, in compliance with 
IEC 60068-2-82, has been proven under extensive testing.
The encapsulant is resistant to cleaning solvent specified in 
IEC 60115-1 
(3)
. 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 IEC 62474 
(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)
• 2011/65/EU Restriction of the use of Hazardous 
Substances Directive (RoHS)
• 2012/19/EU 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.
