A modern mesh filament is used, replacing the old-fashioned hairpin construction. The improved mesh filament design ensures better mechanical rigidity and long lasting concentricity of the filament, providing enhanced linearity, less noise, reduced warm-up variation and longer life. Flying leads are provided for filament and grid connections to eliminate the need for a socket in low-frequency RF and AF modulator applications.<\/p>\n<p>The Svetlana 3CX2500F3\/8251 is manufactured in the Svetlana Electron Devices complex in St. Petersburg, Russia. Svetlana has achieved the improved performance described above with exact replacement compatibility with the 3CX2500F3\/8251 manufactured in the United States.<\/p>\n<p>Outline with dimensions (size: 58k) Page 2 (size: 64k) Page 3 (size: 73k) Page 4 (size: 57k) Typical Characteristics Chart (size 201k)<\/p>\n<p><i>\u0418\u0437 \u0441\u043f\u0440\u0430\u0432\u043e\u0447\u043d\u0438\u043a\u0430 Svetlana \u043d\u0430 \u0441\u0442\u0430\u0440\u043e\u043c \u0441\u0430\u0439\u0442\u0435 \u0410\u0443\u0434\u0438\u043e\u041f\u043e\u0440\u0442\u0430\u043b\u0430 (2006).<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>3CX2500F3 \u2014 \u043c\u043e\u0449\u043d\u044b\u0439 \u0442\u0440\u0438\u043e\u0434 \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0441\u0442\u0432\u0430 \u0437\u0430\u0432\u043e\u0434\u0430 \u00ab\u0421\u0432\u0435\u0442\u043b\u0430\u043d\u0430\u00bb (Svetlana, \u0421\u0430\u043d\u043a\u0442-\u041f\u0435\u0442\u0435\u0440\u0431\u0443\u0440\u0433). \u041d\u0438\u0436\u0435 \u2014 \u043e\u043f\u0438\u0441\u0430\u043d\u0438\u0435 \u043b\u0430\u043c\u043f\u044b \u0438\u0437 \u043a\u0430\u0442\u0430\u043b\u043e\u0433\u0430 Svetlana (\u043d\u0430 \u0430\u043d\u0433\u043b\u0438\u0439\u0441\u043a\u043e\u043c \u044f\u0437\u044b\u043a\u0435, \u043a\u0430\u043a \u0432 \u043e\u0440\u0438\u0433\u0438\u043d\u0430\u043b\u0435) \u0438 \u043f\u043e\u043b\u043d\u044b\u0439 \u0444\u0430\u0439\u043b \u0442\u0435\u0445\u043d\u0438\u0447\u0435\u0441\u043a\u0438\u0445 \u0434\u0430\u043d\u043d\u044b\u0445 \u0434\u043b\u044f \u0441\u043a\u0430\u0447\u0438\u0432\u0430\u043d\u0438\u044f.
