CMB02070X1200GB200

The production process is strictly controlled and follows an extensive set of instructions to ensure repeatability. A uniform and dense carbon film is deposited on a high-grade ceramic body (Al₂O₃). Nickel-plated steel end caps are firmly pressed onto the coated rod. Where applicable, a special laser is used to cut a helical groove smoothly into the resistive layer to achieve the target value without damaging the ceramic. The resistor is covered with a protective coating for electrical, mechanical, and climatic protection. The end caps receive a final pure matte nickel plating. Four (E24) or five (E96) color bands indicate the resistance value and tolerance in accordance with IEC 60062. The determined production results are verified through an extensive testing procedure performed on 100% of individual resistors. This includes comprehensive screening per EN 140401-803, 2.1.2.2 to eliminate products with potential risk of early failure. Only accepted products are placed directly into blister tape in accordance with IEC 60286-3 Type 2a. The resistors are suitable for processing in automatic SMD assembly systems. They are compatible with automatic soldering using wave soldering, reflow soldering, or vapor phase soldering as indicated in IEC 61760-1. The packaging materials resist all cleaning solvents commonly used in the electronics industry, including alcohols, esters, and aqueous solutions. If conformal coatings, potting compounds, and their processes are used, they should be qualified by appropriate means to ensure long-term stability of the overall system. The resistors are completely lead-free (Pb), and the pure matte tin plating is compatible with both lead-free and leaded soldering processes. Solderability is specified within 2 years of production or requalification, but has been demonstrated to remain excellent even after long-term storage exceeding 10 years. The permitted storage duration is 20 years. The resistance of the tin plating to tin whisker growth has been demonstrated through extensive testing. Vishay recognizes the following regulatory systems for hazardous substances: - IEC 62474, Material Declaration for Products of and for the Electrotechnical Industry, which contains a declarable substances list. - Global Automotive Declarable Substance List (GADSL). - REACH Regulation (1907/2006/EC) and its related Substances of Very High Concern (SVHC) list within the supply chain. The product contains no banned substances from the IEC 62474, GADSL, or SVHC lists; see www.vishay.com/how/leadfree for details. The product therefore fully complies with the following directives: - 2000/53/EC End-of-Life Vehicles Directive (ELV) and Annex II (ELV II). - 2011/65/EU Restriction of Hazardous Substances Directive (RoHS) and amendment 2015/863/EU. - 2012/19/EU Waste Electrical and Electronic Equipment Directive (WEEE). Vishay is committed to eliminating conflict minerals from its supply chain; see the Conflict Minerals Policy at: www.vishay.com/doc?49037.
