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
information on the general nature of thermal resistance.

The resistance value is influenced by the resistance of the terminations. The exact resistance value of the soldered part on the
PCB may deviate depending on e.g. solder quantity, pad layout, and soldering method. The resistance value of the unmounted
part can be verified by a 4-point probe on the top side termination as shown below.

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 substrate (Al
2
O
3
) and conditioned to
achieve the desired temperature coefficient. Specially
designed inner contacts are deposited on both sides. A
special laser is used to achieve the target value by smoothly
cutting a meander 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.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. This
includes full screening for the elimination of products with
potential risk of early field failures (feasible for R
10
).
Only accepted products are laid directly into the paper tape
in accordance with
IEC 60286-3 Type 1a
(1)
.
Vishay Beyschlag
The products do not contain any of the banned substances
as per IEC 62474, GADSL, or the SVHC list, see

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.
APPROVALS
Where applicable the resistors are tested within the
IECQ-CECC Quality Assessment System for Electronic
Components to the detail specification
EN 140401-801
which refers to
EN 60115-1, EN 60115-8
and the variety of
environmental test procedures of the
IEC 60068
(1)
series.
The detail specification refers to the climatic category
55/125/56, which relates to the “standard operation mode”
of this datasheet. The MCW 0406 AT is AEC-Q200 qualified.
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 03-3-1,
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
(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 RoHS compliant; the pure tin plating
provides
compatibility
with
lead
(Pb)-free
and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven by
extensive testing.
