12AT7WA

      The 12AT7WA is designed as reliable miniature double triode suitable for use in amplifier, mixer, oscillator, multivibrator and computer circuits.The high amplification factor makes it ideal for audio amplifier service where a gain of 40 is easily realized.The low plate resistance plus the ample peak plate current make this type ideal for pulse amplifier and low power servo amplifier service.This type is controlled for cathode interface and is designed for dependable operation under conditions of shock and vibration encountered in mobile aircraft and missile applications.A heater center tap is provided to permit operation at 12.6V or parallel operation at 6.3V.
      Some absolute maximum ratings have been concluded into several points as follow.The first one is about its maximum lmpact acceleration which would be 630G.The second one is about its maximum vibrational acceleration which would be 2.5G.The third one is about its maximum bulb temperature which would be 165°C.The next one is about its altitude which would be 60000ft.That are all the maximum ratings.
     Also there are some electrical specifications about it.The first one is about its heater voltage which would be min 11.4V and typ 12.6V and max 13.9V.The second one is about its plate voltage which would be typ 250Vdc and max 330Vdc.The third one is about its grid voltage which would be min -55Vdc.The next one is about its plate dissipation (per plate) which would be typ 2.5W.The next one is about its heater-cathode voltage which would be max +/- 100V.The next one is about its plate current (per plate) which would be min 7mA and typ 10mA and max 14mA.The next one is about its cathode resistance which would be typ 200.The next one is about its transconductance which would be min 4500u and typ 5500u and max 6500u.The next one is about its amplification factor which would be min 50 and typ 60 and max 70.And so on.For more information please contact us.
