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 super high
grade (96 % Al2O3) ceramic substrate and conditioned to
achieve the desired temperature coefficient. Specially
designed inner contacts are deposited on both sides. A
special laser is used to achieve the target value by smoothly
cutting a meander groove in the resistive layer without
damaging the ceramics. For the high ohmic range, optimized
Cermet products provide comparable properties. 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.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. Only
accepted products are laid directly into the paper tape in
accordance with EN 60286-3.
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. The encapsulation is resistant to all cleaning
solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
resistors are RoHS compliant, 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 GADSL1) and the CEFIC-
EECA-EICTA2) list of legal restrictions on hazardous
substances. This includes full compliance with the following
directives:
•2000/53/EC End of Vehicle life Directive (ELV) an Annex II
(ELV II)
•2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
•2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
Solderability is specified for 2 years after production or
requalification. The permitted storage time is 20 years.

APPROVALS
The resistors are tested in accordance with EN 140401-801
(superseding CECC 40401-801) which refers to EN 60115-1
and EN 140400. 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. The
release certificate for "Technology Approval Schedule" in
accordance with CECC 240 001 based on EN 100114-6 is
granted for the Vishay BEYSCHLAG manufacturing process.
