THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 RW, RW E, RW Ni www.vishay.com Vishay Draloric DESCRIPTION ASSEMBLY The rugged design and durable coating of Vitreous wirewound resistors enable them to withstand extreme environmental stress. For this reason they are well suited for use in demanding environmental conditions. The glaze is fired layer by layer several times at high temperatures (> 600 °C). This vitreous coating is designed for high stability and a long lifetime in humid environments and is resistant to all cleaning chemicals commonly used in the electronic industry. The resistors are available with lug style terminals for soldering assembly processes or with fast plug terminals (FST style) for assembly / disassembly processes. The terminals of the resistors are completely lead (Pb)-free. The special tin plating used provides compatibility with lead (Pb)-free and lead-containing soldering processes. Production is strictly controlled and follows an extensive set of instructions established for reproducibility. The winding is done with specific materials on a specially developed fine ceramic body (Al2O3). The ceramic used meets the highest requirements against mechanical resistance, thermal shock, dielectric strength, and insulation resistance at high temperatures. With different diameters and turn spacings, a large ohmic value range can be offered. The resistors are marked with resistance and tolerance. The RW series meets single lot / date code packaging requirements. 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 (1) • 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) (3) 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. Special lugs are available on request, please inquire at [email protected]. 3D-Models are available on request, please inquire at [email protected]. Different mounting accessories are available, see the datasheet: www.vishay.com/doc?21015. The slider of the adjustable type should be only moved after removal of voltage and sufficient loosening of the screw. APPLICATION INFORMATION The power dissipation of the resistor generates a temperature rise with respect to the ambient. The permissible dissipation is derated for temperatures above 40°C, as shown in the derating diagram, in order to avoid overheating of the resistor. The heat dissipated from the resistor may affect adjacent components, hence proper clearance will be required in order to avoid overheating. All materials used are non-flammable and inorganic. These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. RELATED PRODUCTS In lower continuous power applications and less demanding environmental conditions the cement coated alternative, like the ZWS series might be suitable, see the datasheet: “Cemented Wirewound Resistors with Lugs” www.vishay.com/doc?21010 For low ohmic values and rated dissipation up to 1000 W, there is the vitreous coated GBS series, see the datasheet: “Vitreous Wirewound Resistors with Corrugated Ribbon” www.vishay.com/doc?21004 For higher power dissipation and different lugs, there is the vitreous coated GWS series, see the datasheet: “Vitreous Wirewound Resistors with Lugs” www.vishay.com/doc?21003 Notes (1) The IEC 62474 list of declarable substances is maintained in a dedicated database, which is available at http://std.iec.ch/iec62474.
