    • Medical equipment
    Note
    (1) Please refer to APPLICATION INFORMATION below.
    APPLICATION INFORMATION
    The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow
    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.
    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. At the maximum permissible film temperature of 155 °C the useful lifetime is specified for 8000 h. The
    designer may estimate the performance of the particular resistor application or set certain load and temperature limits in order
    to maintain a desired stability.

    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 (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 colour
    code rings designate the resistance value and tolerance in
    accordance with IEC 60062 (1).
    The result of the determined production is verified by an
    extensive testing procedure performed on 100 % of the
    individual resistors. This includes full screening for the
    elimination of products with a potential risk of early field
    failures (feasible for R  10 ) 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 (1) or
    bulk case in accordance with IEC 60286-6 (1).
    .
    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 (1). 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.
    The resistors are completely lead (Pb)-free, the pure tin
    plating provides compatibility with lead (Pb)-free and lead
    containing soldering processes. 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.
    The immunity of the plating against tin whisker growth has
    been proven under extensive testing.
    All products comply with the JIG 101 list of legal restrictions
    on hazardous substances.
    This includes full compliance with the following directives:
    • 2000/53/EC End of Life Vehicle 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 (1) series.
    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 IECQ 03-1. The release certificate for
    “Technology Approval Schedule” in accordance with
    CECC 240001 based on IECQ 03-3-1is granted for the
    Vishay Beyschlag manufacturing process.

    TESTS AND REQUIREMENTS
    All tests are carried out in accordance with the following
    specifications:
    EN 60115-1, generic specification (includes tests)
    EN 140400, sectional specification (includes schedule for
    qualification approval)
    EN 140401-803, detail specification (includes schedule for
    conformance inspection)
    The components are approved in accordance with the
    IECQ-CECC-system, where applicable. The following table
    contains only the most important tests. 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 (1)
    and under standard atmospheric conditions in accordance
    with IEC 60068-1 (1), 5.3. A climatic category temperature is
    applied, defined by the lower category temperature (LCT),
    the upper category temperature (UCT), and the number of
    days of the damp heat steady state test. (56).
    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 1060 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.

    Note
    • Color code marking is applied according to IEC 60062 (1) 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 yellow band between the 4th and 5th full band indicates TC25.
    PATTERN STYLES FOR MELF RESISTORS
    Notes
    • 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. Specified power rating above 125 °C requires dedicated heat-sink pads, which to a great extend depend
    onboard materials and design. The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g.
    in standards IEC 61188-5-x (1), or in publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are
    also strongly influenced by many other parameters.
    Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to “standard operation
    mode”. Please note however that applications for “power operation mode” require special considerations for the design of solder pads and
    adjacent conductor areas.
    (1) The quoted IEC standards are also released as EN standards with the same number and identical contents.
