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.
(1) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.

• Color code marking is applied according to IEC 60062 (3) in five bands. 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. An interrupted band between the 4th and 5th full band indicates the temperature coefficient (yellow = TC25, orange = TC15).

list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A homo-
geneous 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 metallised rods. A special laser is
used to achieve the target value by smoothly cutting a helical
groove in the resistive layer without damaging the ceramics.
A further conditioning is applied in order to stabilise the
trimming result. 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
2000/53/EC End of Vehicle life Directive (ELV) and Annex II
(ELV II)
2011/65/EU Restriction of the use of Hazardous
Substances Directive (RoHS)
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.
IEC 60062 (3)
.
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual resistors. This includes pilse load screening (for R
10 ) and additional non-linearity screening (for R 30 )
for the elimination of products with a potential risk of early life
failures 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 II (3) or bulk case in accordance with
Conformity is attested by the use of the CECC logo (
) as
the mark of conformity on the package label.
Vishay Beyschlag has achieved “Approval of
Manufacturer” in accordance with IEC QC 001002-3,
clause 2. The release certificate for “Technology Approval
Schedule” in accordance with CECC 240001 based on
IEC QC 001002-3, clause
6
is granted for the
IEC 60286-6 (3)
.
Vishay Beyschlag manufacturing process.
ASSEMBLY
The resistors are qualified according to AEC-Q200.
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 or requalification, however, excellent solderability
is proven after extended storage in excess of 10 years. The
permitted storage time is 20 years.

(www.vishay.com/doc?28713)
For products with tighter precision specification, see the
datasheet:
The resistors are completely lead (Pb)-free, the pure tin
plating provides compatibility with lead (Pb)-free soldering
processes. The immunity of the plating against tin whisker
growth has been proven under extensive testing.
• “High Precision MELF resistors”
(www.vishay.com/doc?28715)
Resistors are available with established reliability in
accordance with EN 140401-803 Version E. Please refer to
datasheet “MELF Resistors with Established Reliability”
(www.vishay.com/doc?28707).
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.

Notes
(1) The pulse load stability of professional MELF resistors applies for precision resistors also. However, severe pulse loads are likely to jeopardize
precision stability requirements.
(2) Wave soldering is not recommended.
(3) Special requirements apply to MICRO-MELF, MMU 0102:
