TII 3-Electrode Miniature Gas Tube

47BT SERIES WITH RADIAL LEADS


DESCRIPTION

The TII 47BT is a miniature three- electrode tube suitable for use on carrier and other communication equipment requiring higher DC Holdover. Mounts in socket for .040" diameter leads or can be direct wired in printed wiring boards. Leads tin plated for good solderability.


Dimensions: 0.42" long x 0.30" dia. x 0.21" lead length
Weight: 0.1 oz.
Standard Package: 100 pieces
