DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of metal oxide 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. Mostly, 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 % tin are welded to the termination caps. The
resistor elements are covered by a green 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
(1)
. WK2 and
WR4 are color coded while WR5 and WK8 are print marked.
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
(1)
.
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
• 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) 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 encapsulation is resistant to cleaning solvent
(3)
specified in IEC 60115-1. The suitability of conformal
coatings, potting compounds and their processes, if
applied, shall be qualified by appropriate means to ensure
the long-term stability of the whole system
APPROVALS
WK2 and WR4 are AEC-Q200 qualified which makes these
products ideal to be used in automotive applications.
