Note:
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* 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 approx, 50 % wider than the other bands.
An interrupted band between the 4rd and 5th full band identifies the temperature coefficient.

MMU 0102, MMA 0204, MMB 0207 - Precision
Vishay Beyschlag
DESCRIPTION
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 (85 % Al
2
O
3
, for MICRO-MELF: 96 % Al
2
O
3
)
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
IEC 60062*.
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual resistors. Only accepted products are laid directly
into the blister tape in accordance with
IEC 60 286-3*
or bulk
case in accordance with
IEC 60286-6*.
Precision MELF Resistors
APPROVALS
The resistors are tested in accordance with
EN 140401-803
(superseding
CECC 40401-803)
which refers to
EN 60115-1, EN 140400
and the variety of enviromental test
procedures of the
IEC 60068*
series. Approval of conformity
is indicated by the
CECC
logo 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 Vishay
BEYSCHLAG manufacturing process.
SPECIALS
On request, resistors are available with established reliability
in accordance with
EN 140401-803 Version E.
Please refer
to the special data sheet for information on failure rate level,
available resistance ranges and ordering codes.
Note:
* The quoted IEC standards are also released as EN standards with
the same number and identical contents.
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*.
Excellent solderability is proven, even after
extended storage in excess of 10 years. The encapsulation
is resistant to all cleaning solvents commonly used in the
electronics industry, including alcohols, esters and aqueous
solutions. 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.
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:
•
