CHARACTERISTICS
Test methods per ITU-T K.12
   

UL File E153537. Electrodes are nickel plated Available without preionizing material: add’Y’ to the model
Lead wires are tin plated copper number (i.e., 2027-23-AY). Disregard first dc sparkover value.
Model number marking on tube: 27-xxxV After discharge: sparkover limits increase by 10 %, measured
Ceramic is treated with AntiTrac moisture proofing 24 hours after discharge, resistance > 108ohm
BT1 tape sequencing per EIA RS-296-D, 1000 pcs/spool †Tube will remain functional without shorting or venting
