A homogeneous film of metal alloy is deposited on a high grade ceramic body (85 % Al2O3) and conditioned to achieve the desired temperature stability. Nickel plated steel terminations are firmly pressed on the metallised rods. A special laser is used to achieve the target value by smoothly cutting in the resistive layer without damaging the ceramics. A further conditioning is applied in order to stabilise 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 tin on nickel plating. Five colour rings designate the resistance value and tolerance in accordance with IEC 60062. Additional colour dots near the fourth ring are used to identify the temperature coefficient. APPROVALS The resistors are tested in accordance with EN 140401-803 which refers to EN 60115-1, EN 140400 and the variety of enviromental test procedures of the IEC 60068 series. Approval of conformity is indicated by the CECC logo on the package label. Vishay BEYSCHLAG has achieved "Approval of Manufacturer" in accordance with EN 100114-1. The release certificate for "Technology Approval Schedule" in accordance with CECC 240001 based on EN 100114-6 is granted for the Vishay BEYSCHLAG manufacturing process. The result of the determined production is verified by an extensive testing procedure under strict temperature control, performed on 100 % of the individual resistors. Only accepted products are laid directly into the antistatic blister tape in accordance with IEC 60286-3. ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using reflow or vapour phase. Excellent solderability is proven, even after extended storage in excess of 10 years. The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions.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. All products comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances. This includes full compatibility with the European RoHS directive.
