So while trying to interface a 5 V SPI to a 3.3 V SPI device, using the inline resistor method outlined here, I discovered that at high clock speeds (above 200 kHz), my clock signal was being corrupted by the inductance in the resistor (with an oscilloscope, the clock looks signal looks triangular shaped). I am using carbon film (through hole) resistors for prototyping, and I heard that these can have high parasitic inductance and are 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 20 MHz.
