Notes
• 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.
(1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow 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.
(2)
Specified power rating requires dedicated heat-sink pads.

Note
• Color code marking is applied according to IEC 60062
(3)
in four bands (E24 series) or 5 bands (E96 or E192 series). Each color band appears
as a single solid line, voids are permissible if at least
2
/
3
of the band is visible from each radial angle of view. The last color band for tolerance
is approximately 50 % wider than the other bands. An interrupted yellow band between the 4
th
and 5

Notes
• Resistance ranges printed in bold are preferred TCR/tolerance combinations with optimized availability.
• Resistance values to be selected for ± 5 % and ± 2 % tolerance from E24, for ± 1 % tolerance from E24 and E96 and for ± 0.5 % tolerance
from E24 and E192.
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 tin on nickel plating.
Four or 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 performed on 100 % of the
individual resistors. This includes pulse load screening (for
R
10
)
and additional non-linearity screening (for
R
30
)
for the elimination of products with a potential risk of early life
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 II
(3)
or bulk case in accordance with
IEC 60286-6
(3)
.
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 Vehicle Life 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
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.
Conformity is attested by the use of the
CECC
logo (
) as
the mark of conformity on the package label.
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.
The resistors are qualified according to AEC-Q200.
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic soldering
using wave, 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.
