Precision Leaded Resistors Vishay Beyschlag
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) and conditioned to achieve the
desired temperature coefficient. Nickel plated steel
termination caps are firmly pressed on the metallized 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. Connecting wires of
electrolytic copper plated with 100 pure tin are welded to the
termination caps. The resistors are covered by 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 stuck
directly on the adhesive tapes in accordance with
IEC 60286-1.
ASSEMBLY
The resistors are suitable for processing on automatic
insertion equipment and cutting and bending machines.
Excellent solderability is proven, even after extended
storage. They are suitable for automatic soldering using
wave or dipping. 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. The immunity of the
plating against tin whisker growth has been proven under
extensive testing. All products comply with the
CEFIC-EECA-EICTA list of legal restrictions on hazardous
substances. This includes full compliance with the following
directives:
•2000/53/EC End of Vehicle Life Directive (ELV)
•
2000/53/EC Annex II to End of Vehicle Life Directive (ELV II)
•2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
•2002/96/EC Waste Electrical and Electrical Equipment
Directive (WEEE)
APPROVALS
Where applicable, the resistors are tested in accordance with
CECC 40101-806 which refers to EN 60115-1 and
EN 140100. Approval of conformity is indicated by the CECC
logo on the package label.
Vishay BEYSCHLAG has achieved “Approval of
Manufacturer” in accordance with EN 100114-1.
SPECIALS
On request, resistors are available with established reliability
in accordance with CECC 40101-806 Version E. Please
refer to the special datasheet for information on failure rate
level, available resistance ranges and ordering codes.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
following specifications:
EN 140000/IEC 60115-1, Generic specification (includes
tests)
EN 140100/IEC 60115-2, Sectional specification (includes
schedule for qualification approval)
CECC 40101-806, Detail specification (includes schedule for
conformance inspection)
Most of the components are approved in accordance with the
European CECC-system, where applicable. The Test
Procedures and Requirements 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 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 1060 mbar).
For testing the components are mounted on a test board in
accordance with IEC 60115-1, 4.31 unless otherwise
specified.
