Description

The Svetlana 4CPW10,000R has a directly-heated thoriated tungsten mesh filament for mechanical ruggedness. This modern mesh filament design is superior to the old hairpin design of the 1950's. The high voltage standoff of the Svetlana 4CPW10,000R is 25 KVDC and the peak current rating is 24 amperes. The Svetlana 4CPW10,000R is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for the 4CPW10,000 or Y442 manufactured in the United States, England and elsewhere.
