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
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 low-inductivity non-helical groove in the
resistive layer without damaging the ceramics. 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 colour code rings designate the
resistance value and tolerance in accordance with
IEC 60062. Additional black dots near the 3rd colour ring
identify the special HF product.
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 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 GADSL
(1)
and
the CEFIC-EECA-EICTA
list of legal restrictions on
hazardous substances. This includes full compatibility with
the following directives:
• 2000/53/EC End of Vehicle Life Directive (ELV) and
Annex II (ELVII)
• 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.
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.
