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.
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
www.vishay.com/doc?49037
.
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)
• 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.
