Supply Voltage: 1000 V dc, K: Cathode, Dy: Dynode, P: Anode
Do not cooled the R4519 to lower than -30
C. The fixing glue of the base may cause cracking in the glass bulb.
Use the R4519-01 instead. The voltage divider should be assembled on a PC board or similar with at least 5 to 10 mm apart from the PMT stem.
