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. Furthermore, a
high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board
materials may be required to maintain the reliability of the assembly.

2)

Specified power rating requires dedicated heat-sink pads.

3)

Film temperatures above the specified range may be permissible, e.g. 175 °C. Please contact the factory for details.

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 colour band for tolerance
is approximately 50 % wider than the other bands. An interrupted yellow band between the 4th and 5th full band indicates the temperature

Professional MELF Resistors

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 % Al

, for MICRO-MELF: 96 % Al2O3)

2O3

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 colour 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 GADSL

TEST AND REQUIREMENTS

All tests are carried out in accordance with the following
specifications:

EN 60115-1, generic specification

EN 140400, sectional specification

EN 140401-803, detail specification

The components are approved in accordance with the
IECQ-CECC-system, where applicable. For the full test
schedule refer to the documents listed above. The testing
also covers most of the requirements specified by
EIA/IS-703 and JIS-C-5202.

The tests are carried out in accordance with IEC 60068* and
under standard atmospheric conditions in accordance with
IEC 60068-1, 5.3*. Climatic category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days) is valid.

Unless otherwise specified the following values apply:

Temperature: 15 °C to 35 °C

Relative humidity: 45 % to 75 %

Air pressure: 86 kPa to 106 kPa (860 mbar to 1 060 mbar).

The components are mounted for testing on printed-circuit
boards in accordance with EN 140400, 2.3.3, unless
otherwise specified.

The requirements stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-803. However, some
additional tests and a number of improvements against those
minimum requirements have been included. The stated
requirements for long-term tests are typically fulfilled with a
statistical safety of at least + 5 s.
