[Milsurplus] CarbonFilm / Metal Film Resistors

[Scott Johnson]

Most carbon and metal film resistors have a laser cut helix that will 
exhibit some inductance, usually the data sheet will give that figure. 
There are special carbon film resistors that basically use a chip resistor 
with leads attached with an overmold that are designed for high frequencies. 
See the Vishay product catalog.

When replacing carbon composition resistors, at  what frequencies do I need 
to be concerned about the inductive effects of the newer carbon film and 
metal film resistors, I assume the metal film would be far more of an issue 
I have seen some vague suggestions but not much specific info. Has anyone 
seen any real world problems in this area?
