DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous film of special metal alloy is deposited on a
high grade ceramic substrate (Al2O3) 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. The resistor elements are covered
by a unique protective coating designed for electrical,
mechanical and climatic protection. The terminations
receive a final pure matte 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. This
includes full screening for the elimination of products with
potential risk of early field failures (feasible for R 10 ).
Only accepted products are laid directly into the paper tape
in accordance with IEC 60286-3 Type 1a (1).
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor 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, potting compounds
and their processes, if applied, shall be qualified by
appropriate means to ensure the long-term stability of the
whole system.
The resistors are RoHS-compliant; the pure matte tin plating
provides compatibility with lead (Pb)-free and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven under
extensive testing.
MATERIALS
Vishay acknowledges the following systems for the
regulation of hazardous substances:
• IEC 62474, Material Declaration for Products of and for the
Electrotechnical Industry, with the list of declarable
substances given therein (2)
• The Global Automotive Declarable Substance List
(GADSL) (3)
• The REACH regulation (1907/2006/EC) and the related list
of substances with very high concern (SVHC) (4) for its
supply chain
The products do not contain any of the banned substances
as per IEC 62474, GADSL, or the SVHC list, see

APPROVALS
The resistors are approved within the IECQ-CECC Quality
Assessment System for Electronic Components to the detail
specification EN 140401-801 which refers to EN 60115-1,
EN 60115-8 and the variety of environmental test
procedures of the IEC 60068 (1) series. The detail
specification refers to the climatic categories 55/125/56,
which relates to the “standard operation mode” of this
datasheet.
Conformity is attested by the use of the CECC logo ( ) as
the mark of conformity on the package label.
The resistors are qualified according to AEC-Q200.
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 03-3-1 is
granted for the Vishay Beyschlag manufacturing process.
