APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal
resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted
film temperature is not exceeded.
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.

Note
• The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to
different film temperatures and different achievable load-life stability (drift) of the resistance value. A suitable low thermal resistance of the
circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please
consider the application note “Thermal Management in Surface-Mounted Resistor Applications” (www.vishay.com/doc?28844) for

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 (Al
2
O
3
) and conditioned to achieve the
desired temperature coefficient. Nickel plated steel
termination caps are firmly pressed on the metallised 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. The resistor elements are
covered by a protective coating designed for electrical,
mechanical and climatic protection. The terminations
receive a final pure matte tin on nickel plating. Four or five
color code rings designate the resistance value and
tolerance in accordance with
IEC 60062
(1)
.
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual resistors. This includes full screening for the
elimination of products with a potential risk of early field
failures according to EN 140401-803, 2.1.2.2. Only
accepted products are laid directly into the blister tape in
accordance with
IEC 60286-3, Type 2a
(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
(2)
• The Global Automotive Declarable Substance List
(GADSL)
(3)
• The REACH regulation (1907/2006/EC) and the related list
of substances with very high concern (SVHC)
(4)
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 SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor phase as shown in
IEC 61760-1
(1)
. 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, potting compounds
and their processes, 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 matte
tin plating provides compatibility with lead (Pb)-free and
lead containing soldering processes. Solderability is
specified for 2 years after production or requalification,
however, excellent solderability is proven after extended
storage in excess of 10 years. The permitted storage time is
20 years. The immunity of the plating against tin whisker
growth has been proven under extensive testing.
APPROVALS
Where applicable, the resistors are tested in accordance
with
EN 140401-803
which refers to
EN 60115-1,
EN 60115-8
and the variety of environmental test
procedures of the
IEC 60068
(1)
series.
