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.

in five bands. Each color band appears as a single solid line, voids are permissible
if at least

SMM0204 .... EN803 E8
Vishay Draloric
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 metallized rod. 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.
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. Only accepted products are placed into
the blister tape in accordance with
IEC 60286-3
(3)
, Type II.
MINI-MELF Resistors with Established Reliability
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)
•
2002/95/EC Restriction of the
Substances Directive (RoHS)
use
of
Hazardous
•
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 (
the mark of conformity on the package label.
) as
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. The permitted storage time is 20 years.
The resistors are completely lead (Pb)-free, the pure tin
plating provides compatibility with both, lead (Pb)-free and tin
lead (SnPb) based 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.
