| I have a choice of using either of these resistor types in a voltage divider that I need to build. It will be placed in line between my preamp and amp to lower the overall gain of my system. The preamp is a Pass X1, which it turns out uses the same RN55E series resistors internally (so I'm told from Pass Labs). The PTF-56 have a better temperature stability rating (5ppm), but I'm not sure what the voltage noise is for either series, or which series has better bandwidth characteristics. Can anyone provide any info that could help me decide? |
