DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility.
MATERIALS
Vishay acknowledges the following systems for the
regulation of hazardous substances:
A
homogeneous film of 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 fine trimming
the resistive layer without damaging the ceramics. A further
conditioning is applied in order to stabilize the trimming
result. The resistor elements are covered by a 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 on 100 % of the
individual chip resistors. Only accepted products are laid
directly into the tape in accordance with IEC 60286-3 Type

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.

Directive (WEEE)
Vishay pursues the elimination of conflict minerals from its
supply chain, see the Conflict Minerals Policy at
www.vishay.com/doc?49037.
RELATED PRODUCTS
The resistors are RoHS compliant, the pure matte 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.
