MMU 0102 VG03, MMA 0204 VG03 and MMB 0207 VG03
thin film MELF resistors with established reliability are the
perfect choice for all high-reliability applications typically
found in the fields of military, aircraft and spacecraft
electronics. These versions supplement the families of
professional and precision MELF resistors MMU 0102,
MMA 0204 and MMB 0207.
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.
- The failure rate level E6 corresponds to MIL Level P.

DIMENSIONS
Note: Color code marking is applied according to EN 60062* in four bands (E24 series) or 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. An interrupted blue band between the 1st and 2nd full band indicates the
failure rate level E6. An interrupted orange band between the 4th and 5th full band indicates the temperature coefficient of 15 ppm/K.

Revision: 18-Jul-06 5
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 (85 % Al2O3, for MICRO-MELF: 96 % 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. 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.
Four or 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 60286-3* or bulk
case in accordance with IEC 60286-6*.
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 GADSL1) and the CEFIC-
EECA-EICTA2) 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 use of Hazardous
Substances Directive (RoHS)
•2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
1) Global Automotive Declarable Substance List, see www.gadsl.org
2) CEFIC (European Chemical Industry Council), EECA (European
Electronic Component Manufacturers Association), EICTA
(European trade organisation representing the information and
communications technology and consumer electronics), see
www.eicta.org -> issues -> environment policy -> chemicals ->
chemicals for electronics
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 environmental 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 240 001 based on
IEC 001002-3, clause 6 is granted for the Vishay
BEYSCHLAG manufacturing process.
