THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Notes • Resistance ranges printed in bold are preferred TCR/tolerance combinations with optimized availability. • Resistance values to be selected for ± 5 % and ± 2 % tolerance from E24, for ± 1 % tolerance from E24 and E96 and for ± 0.5 % tolerance from E24 and E192. 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 high grade ceramic body (Al2O3) and conditioned to achieve the desired temperature coefficient. Nickel plated steel termination caps are firmly pressed on the metallised rods. A special laser is used to achieve the target value by smoothly cutting a helical 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. Four or five color code rings designate the resistance value and tolerance in accordance with IEC 60062 (3). The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. This includes pulse load screening (for R 10 ) and additional non-linearity screening (for R 30 ) for the elimination of products with a potential risk of early life failures according to EN 140401-803, 2.1.2.2. Only accepted products are laid directly into the blister tape in accordance with IEC 60286-3, Type II (3) or bulk case in accordance with IEC 60286-6 (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 (3). Solderability is specified for 2 years after production or requalification, however, excellent solderability is proven after extended storage in excess of 10 years. The permitted storage time is 20 years. The resistors are completely lead (Pb)-free, the pure tin plating provides compatibility with lead (Pb)-free soldering processes. The immunity of the plating against tin whisker growth has been proven under extensive testing. 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, if applied, shall be qualified by appropriate means to ensure the long-term stability of the whole system. All products comply with the GADSL (1) and the CEFIC-EECA-EICTA (2) list of legal restrictions on hazardous substances. This includes full compliance with the following directives: 2000/53/EC End of Vehicle Life Directive (ELV) and Annex II (ELV II) 2011/65/EU Restriction of the use of Hazardous Substances Directive (RoHS) 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE) APPROVALS The resistors are approved within the IECQ-CECC Quality Assessment System for Electronic Components to the detail specification EN 140401-803 which refers to EN 60115-1, EN 140400 and the variety of environmental test procedures of the IEC 60068 (3) series. Conformity is attested by the use of the CECC logo ( ) as the mark of conformity on the package label. Vishay Beyschlag has achieved “Approval of Manufacturer” in accordance with IEC QC 001002-3, clause 2. The release certificate for “Technology Approval Schedule” in accordance with CECC 240001 based on IEC QC 001002-3, clause 6 is granted for the Vishay Beyschlag manufacturing process. The resistors are qualified according to AEC-Q200.
