So while trying to interface a 5v SPI to a 3.3v SPI device, using the inline resistor method outlined below,

I discovered that at high clock speeds (above 200khz), my clock signal was being corrupted by the inductance in the resistor. I am using carbon film (through hole) resistors for prototyping and I heard that these can have high parasitic inductance and not suitable for high frequency use. Is this information correct? 

What types of resistor instead should I be getting (digikey link would be appreciated)? Right now, I'm just working on a protoboard but eventually I would like to manufacture this prototype on a PCB using surface mount components. It seems like from what I read about surface mount resistors, the inductance is not typically a problem for applications under 20Mhz.
