APPLICATION INFORMATION
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow
support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is
not exceeded. Furthermore a high level of ambient temperature or of power dissipation may raise the temperature of the solder
joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly.
These resistors do not feature a lifetime limitation when operated within the limits of rated dissipation, permissible operating
voltage and permissible film temperature. However, the resistance typically increases due to the resistor’s film temperature over
operating time, generally known as drift. The drift may exceed the stability requirements of an individual application circuit and
thereby limits the functional lifetime.

DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of special 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 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. The resistor elements are
covered by a unique protective coating designed for
electrical, mechanical, and climatic protection. The
terminations receive a final pure tin on nickel plating. Five
color code rings designate the resistance value and
tolerance in accordance with
IEC 60062
(3)
.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual resistors. This includes
full screening for the elimination of products with a potential
risk of early field failures. Only accepted products are laid
directly into the blister tape in accordance with
IEC 60286-3, Type 2a
(3)
.
Vishay Beyschlag
All products comply with the
GADSL
(1)
and the
CEFIC-EECA-EICTA
(2)
list of legal restrictions on
hazardous substances. This includes full compliance 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)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
APPROVALS
Where applicable the resistors are approved within the
IECQ-CECC Quality Assessment System for Electronic
Components to the detail specification
EN 140401-803
which refers to
EN 60115-1, EN 140400
and the variety of
environmental test procedures of the
IEC 60068
(3)
series.
Vishay
Beyschlag
has
achieved
“Approval
of
Manufacturer”
in accordance with
IECQ 03-1.
The release
certificate for “Technology
Approval Schedule”
in
accordance with
CECC 240001
based on
IECQ 03-3
is
granted for the Vishay Beyschlag manufacturing process.
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using reflow or vapour phase as shown in
IEC 61760-1
(3)
.
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 resistors are completely lead (Pb)-free, the pure tin
plating provides compatibility with lead (Pb)-free soldering
processes. The immunity of the plating against tin whisker
growth has been proven under extensive testing.
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.
