Specified power rating requires dedicated mounting conditions to achieve the required thermal resistance
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.

DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A cermet film
layer and a glass-over are deposited on a high grade (Al
2
O
3
)
ceramic substrate with its prepared inner contacts on both
sides. A special laser is used to achieve the target value by
smoothly fine trimming 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.
The result of the determined production is verified by an
extensive testing procedure on 100 % of the individual chip
resistors. Only accepted products are laid directly into
the tape in accordance with
IEC 60286-3 Type 1a and
Type 2a
(1)
.
Vishay Draloric
The products do not contain any of the banned
substances as per IEC 62474, GADSL, or the SVHC list,
see
www.vishay.com/how/leadfree.
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.
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 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 under
extensive testing.
APPROVALS
The resistors are qualified according to AEC-Q200.
Where applicable, the resistors are tested in accordance
with
EN 140401-802
which refers to
EN 60115-1,
EN 60115-8
and the variety of environmental test
procedures of the
IEC 60068
(1)
series.
