4 / 7 page CMB 0207 Vishay Beyschlag High Pulse Load MELF Resistor www.vishay.com For technical questions, contact: ff3bresistors@vishay.com Document Number: 28755 82 Revision: 31-Oct-06 DESCRIPTION Production of the CMB 0207 speciality MELF resistor is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous and dense carbon film is deposited on a high grade ceramic body (96 % Al2O3). Nickel plated steel termination caps are firmly pressed on the coated rods. Products with a resistance of 15 Ω or lower are made without trimming, whereas a special laser is used to achieve a target value of 16 Ω or above 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 color code rings designate the resistance value and tolerance in accordance with IEC 60 0623). The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. Only accepted products are laid directly into the blister tape in accordance with IEC 60 286-33). 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 61760-13). 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 GADSL1) and the CEFIC- EECA-EICTA2) 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) • 2002/95/EC Restriction of the use of Hazardous Substances Directive (RoHS) • 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE) Notes 1. Global Automotive Declarable Substance List, see www.gadsl.org 2. CEFIC (European Chemical Industry Council), EECA (European Electronic Component Manufacturers Association), EICTA (European trade organisation representing the information and communications technology and consumer electronics), see www.eicta.org -> issues -> environment policy -> chemicals -> chemicals for electronics APPROVALS Where applicable the resistors are tested in accordance with EN 140401-803 which refers to EN 60115-1, EN 140400 and the variety of environmental test procedures of the IEC 600683) series. 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. Note 3. The quoted IEC standards are also released as EN standards with the same number and identical contents. |
