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 (85 % Al
2
O
3
) and conditioned to
achieve the desired temperature coefficient. Nickel plated
steel termination caps are firmly pressed on the metallized
rods. Special laser devices are used repeatedly to achieve
the target value by slowly and 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 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. Script
marking designates the resistance value plus coded TCR
and tolerance.
The result of the determined production is verified by an
accelerated aging (burn-in) and 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.

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 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.
APPROVALS
Where applicable, the resistors are tested in accordance to
EN 60115-1
and
EN 140100.
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.
