Hello, I want to make a high voltage probe (20kV), there are several different types of high voltage resistors with different Materials: Metal film, ceramic and etc The working frequency is 30KHz to 100KHz. Which material should I choose? Thanks |

Primarily, the material choice is concerned with temperature coefficient of resistance. Having said that, the majority of resistors are helically built and thus have parasitic inductance. There are many techniques for constructing resistors to minimize parasitics. Your best bet is to contact one or two manufacturers and ask for recommendations depending on your requirements. |
| David Hess:
At that frequency anything can be used except wirewound, but pay particular attention to the maximum voltage rating which is what distinguishes high voltage resistors from common resistors. |

Define high voltage: 5kV, 20kV 50kV? |
