VOLTAGE REGULATOR

MINIATURE TYPE

COLD CATHODE ANY MOUNTING POSITION



THE 6627/OB2WA IS A MINIATURE, TWO ELECTRODE, INERT-GAS-FILLED, COLD CATHODE TUBE FOR USE AS A VOLTAGE REGULATOR. IT MAINTAINS PRACTICALLY CONSTANT OPERATING VOLTAGE OVER A CURRENT RANGE OF 5 TO 30 MlLLI AMPERES. IT HAS BEEN DESIGNED TO GIVE EXTREMELY SMALL VOLTAGE DRIFT THROUGHOUT LIFE BY CONTROLLED MANUFACTURING PROCESSES. THIS-TUBE HAS BEEN SPECIALLY DESIGNED TO MAINTAIN STABLE OPERATING VOLTAGES THROUGH LIFE, EVEN IN APPLICATIONS WHICH REQUIRE TUBES TO OPERATE CONTINUOUSLY UNDER ENVIRONMENTAL CONDITIONS WHICH RAISE THE BULB TEMPERATURE TO A MAXIMUM OF 150°C

OVER THE RANGE OF 6 TO 10 MILLI AMPERES, THIS TUBE EXHIBITS REFERENCE TUBE CHARACTERISTICS. THE 6627/0B2WA ALSO HAS IMPROVED CHARACTERISTICS FOR SHOCK, VIBRATION, AND DARK BREAKDOWN VOLTAGE.
