The 350 V rating on 3 watt 100 k MOF resistor's on digikey's
site does not indicate if this is ac or dc.. I'm assuming it's
AC RMS.... if so... the DC V rating should be 495 V ???
On a similar note check out NTE brand of MOF resistors available
in only 2% tolerance for their 2 watt units..... and 5% tol for
their 3 watt units. The 2 watt resistor's are rated at 500
V.... and their 3 watt resistor's are rated at 750 v. Again,
they don't say either... so I'm assuming AC RMS.... so add 41% for
DCV.

BTW... I measured a bunch of new NTE 2% 2 watt 1 meg resistor's
for the 1st time last night.... they were all within just .1%
tolerance.. [ 1/10 of one percent] on the low side.
I'd like to know how good the tol actually is on their 3 watt 5%
units. [750 v rated]
