Hi all,

I'm looking for high voltage resistors for electrostatic discharge tests, 470 kohm. The pulse discharge has a rise time of 1 ns, it's about 60 ns long, and the voltage discharge it is up tu 8 kV.

What kind of resistor would I need?

Thanks.

Juan

Ohmite Slim-Mox series (thick film planar); Digikey carries 400K and 500K 1% 5KV, 10KV and 20KV in the $5 region each. Good power rating choices.
Mouser lists a wider variety, but for some strange reason has decided to not stock them anymore (gack!).
1nSec is slow enough that you should not have major problems using a planar as compared to an axial which could be used in a coax configuration for better pulse fidelity.
