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.
Please consider the application note “Thermal Management in Surface-Mounted
(www.vishay.com/doc?28844) for information on the general nature of thermal resistance.
Resistor
Applications”
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

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 (Al2O3) 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 matte 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 Ω).
Only accepted products are laid directly into the paper tape
in accordance with IEC 60286-3 Type 1a (1).
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 (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 matte 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 under
extensive testing.

TESTS AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
EN 60115-1, generic specification
EN 60115-8, sectional specification
EN 140401-801, detail specification
IEC 60068-2-xx, test methods
When applicable, the components are approved under the
IECQ-CECC quality assessment system for electronic
components.
The parameters stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-801. The table presents only
the most important tests, for the full test schedule refer to
the documents listed above. However, some additional
tests and a number of improvements against those
minimum requirements have been included.
The testing also covers most of the requirements specified
by EIA/ECA-703 and JIS-C-5201-1.
The tests are carried out under standard atmospheric
conditions in accordance with IEC 60068-1, 4.3, whereupon
the following values are applied:
Temperature: 15 °C to 35 °C
Relative humidity: 25 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar)
A climatic category LCT / UCT / 56 is applied, defined by the
lower category temperature (LCT), the upper category
temperature (UCT), and the duration of exposure in the
damp heat, steady state test (56 days).
The components are mounted for testing on printed circuit
boards in accordance with EN 60115-8, 2.4.2, unless
otherwise specified.
