Victoreen glass encapsulated resistors

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

Victoreen glass encapsulated resistors

Post by ChrisSmolinski » Sat Dec 04, 2004 4:58 pm

Does anyone know what the maximum rated voltage for these resistors is? I
have seen conflicting values. I've done some googling, but have been unable
to find a datasheet online. Are they even made anymore? I have several, but
don't have an official part number, which may be hampering my datasheet
search.

These are designed for under 200 volt operation!!! They are meant to go in the input grid circuit of a 30 volt tube (5886) or the gate circuit of an FET.

They are NOT suitable for power supply or voltage divider use under high tension. If you use them for this purpose you might get some whacko division characteristics you did not count on.

They are only rated at 1/4 watt dissipation and normally are found in circuits where they dissipate 1/1,000,000 of one watt.

That's what I thought, Richard, thanks. I've got a 40G ohm resistor, rated for
several KV, on order from Mouser, for turning an electrometer into a voltmeter
that won't load down my circuit ;-)
