High voltage metal surge resistors MSR25/37/37L/52 FEATURES * * * * New product Low cost Excellent anti-surge characteristics Good replacement for metal glazed resistors. APPLICATIONS * CRT-RGB witch is used TV,monitor * Devices which need protection surge voltage between power preliminary and secondary. TYPE DESCRIPTION The multi layer metal film is 3 layers deposited on a high grade ceramic body. After that helical groove has been cut by laser at the resistive layer, tinned electrolytic copper wire are welded to the end-caps. The resistors are coated with a brown and blue non flammable lacquer which provides electrical, mechanical, and climatic protection. D Max. Dimensions ( mm ) L1 L2 d max. max.
