866-A

      The 866-A is designed as half-wave mercury vapor rectifier.
      Some electrical characteristics of 866-A have been concluded into several points as follow.The first one is about its voltage which would be min 2.38V and typ 2.5V and max 2.62V.The next one is about its current at 2.5V which would be typ 5A and max 5.4A.The next one is about its heating time at rated voltage which would e min 15 sec.The next one is about its peak tube vltage drop (approx) which would be typ 15V.
      And there are some absolute maximum ratings of 866-A have been also concluded into several points as follow.The first one is about its peak inverse anode voltage which would be max 2500V in 20°C to 80°C and would be max 5000V in 20°C to 70°C and would be max 10000V in 20°C to 60°C.The next one is about its anode current (peak) which would be 2A max in 20°C to 80°C and would be 1A max in 20°C to 70°C and would be 1A max in 20°C to 60°C.The next one is about its anode current (average) which would be 0.5A max in 20°C to 80°C and would be 0.25A max in 20°C to 70°C and would be 0.25A max in 20°C to 60°C.The next one is about its anode current (fault, for duration of 0.1 second maximum) which owuld be 20A max in 20°C to 80°C and would be 20A max in 20°C to 70°C and would be 20A max in 20°C to 60°C.
      Something about 866-A's mechanical.The first one is about its maximum overall length which would be 6-9/19''.The next one is about its maximum seated length which would be 5-3/4'' ± 3/16''.The next one is about its maximum diameter which would be 2-7/16''.The next one is about its weight (approx) which would be 3 oz.The next one is about its cap. which would be medium (JETEC No. C1-5).And so on.For more information about 866-A please contact us.
