VR37 www.vishay.com Vishay BCcomponents High Ohmic/High Voltage Metal Glaze Leaded Resistors FEATURES Technology: Metal glaze R = 33 M U = 3500 V max. max. DC These resistors meet the safety requirements of: UL1676 (510 k to 11 M) File No: E171160 IEC 60065, clause 14.1.a) DIN EN 60065, clause 14.1.a) VDE 0860, clause 14.1.a) CQC, China High pulse loading capability (10 kV) Small size (0309) A metal glazed film is deposited on a high grade ceramic Pure tin plating provides compatibility with lead (Pb)-free body. After a helical groove has been cut in the resistive and lead containing soldering processes layer, tinned electrolytic copper wires are welded to the Compliant to RoHS Directive 2002/95/EC end-caps. The resistors are coated with a light blue lacquer which provides electrical, mechanical, and climatic APPLICATIONS protection. Where high resistance, high stability and high reliability at The encapsulation is resistant to all cleaning solvents in high voltage are required accordance with IEC 60068-2-45.
