DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A homo-
geneous film of metal alloy is deposited on a super high
grade (96 % Al₂ O₃) 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.
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 60 286-3.

ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems and for automatic soldering using wave,
reflow or vapour phase. The encapsulation is resistant to all
cleaning solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
resistors are 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 Electronic Equipment
Directive (WEEE)
Solderability is specified for 2 years after production or
re-qualification. The permitted storage time is 20 years.
APPROVALS
Where applicable, the resistors are tested in accordance with
EN 140 401-801 (superseding CECC 40401-801) which
refers to EN 140 000 (EN 60 115-1) and EN 140 400
(IEC 60 115-8).
