Notes
• The IECQ-CECC approved product versions SMM0204 EN803 E0 and OMM0204 EN803 E0 respectively feature a quality factor Q = 3 for

(1) Please refer to APPLICATION INFORMATION below
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

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 (Al2O3) 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 ceramic. 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 and copper plating for
enhanced temperature cycling stability. 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 (feasible for R 10 ) 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).
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.

DIMENSIONS
Notes
•Color code marking is applied according to IEC 60062 (1) in four bands (E24 series) for 5 % tolerance, or in five 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
