Vishay Beyschlag High Pulse Load Carbon Film Leaded Resistors
DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous and dense carbon film 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 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. 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. 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 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 GADSL (1) and
the CEFIC-EECA-EICTA (2) 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 (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.
