A homogeneous film of metal oxide is deposited on a high grade ceramic body and conditioned to achieve the desired temperature coefficient. Plated steel termination caps are firmly pressed on the metallized rods. Mostly, 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 % tin are welded to the termination caps. The resistor elements are covered by a green protective coating designed for electrical, mechanical and climatic protection. Four or five color code rings designate the resistance value and tolerance in accordance with IEC 60062 (1). WK2 and WR4 are color coded while WR5 and WK8 are print marked. 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 (1). 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 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, in compliance with IEC 60068-2-82, has been proven under extensive testing. The encapsulation is resistant to cleaning solvent (3) specified in IEC 60115-1. 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 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 • The Global Automotive Declarable Substance List (GADSL) (2) • The REACH regulation (1907/2006/EC) and the related list of substances with very high concern (SVHC) for its supply chain The products do not contain any of the banned substances as per IEC 62474, GADSL, or the SVHC list, see www.vishay.com/how/leadfree. Hence the products fully comply with the following directives: • 2000/53/EC End-of-Life Vehicle Directive (ELV) and Annex II (ELV II) • 2011/65/EU Restriction of the Use of Hazardous Substances Directive (RoHS) with amendment 2015/863/EU • 2012/19/EU Waste Electrical and Electronic Equipment Directive (WEEE) Vishay pursues the elimination of conflict minerals from its supply chain, see the Conflict Minerals Policy at www.vishay.com/doc?49037.
