High Current Density Small Dispenser Cathode

---- Features ----

l Stable emission: Cathode current 170mA (Dk=10A/Square Centimeters) at

Cathode temperature 1050 degree centigrade brightness.

l Long life: Stable operation more than 10000 hours with more than 95%

of original cathode current.

l Stable operation after exposed to the air repeatably.

l Improved to suppress excessive Ba evaporation.

---- Applications ----

l High brightness and high resolution display cathode ray tube (CRT).

l Electronic heating

l Other special purpose tubes.
