LSR3700001001KR500

LSR37 Vishay BCcomponents High Voltage Surge Resistor FEATURES High pulse-loading (10 kV as specified) capability (flashes) Good replacement for carbon-composite resistors Lead (Pb)-free solder contacts Pure Tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes Compatible with Restriction of the use of Hazardous Substances (RoHS) directive 2002/95/EC (issue 2004) A metal glazed film is deposited on a high grade ceramic body. After that caps are applied to the rods and tinned APPLICATIONS electrolytic copper wires are welded to these end caps. Application in overload and high voltage pulse hazard The resistors are coated with a light-blue lacquer which circuits (TV-sets, monitors), high power electronic ballasts provides electrical, mechanical and climatic protection. The encapsulation is resistant to all cleaning solvents according to MIL-STD 202E, method 215 and IEC 60068-2-45.
