Description

Z571M is a cold-cathode Nixie numerical/symbol indicator tube. The supplied RFT sheet gives 150 V ignition and 140 V burning voltage, a 170 V minimum operating supply, 1.5–2.5 mA cathode current, and 10 mm side-viewed symbols. Z571M is tabulated directly in the supplied RFT display-tube data sheet.
