If you wanted a precision RF instrument to last a long time without
significant component drift, would you use carbon film or metal oxide
resistors?
Assumptions:
(1) Little to no RF power dissipated in the resistors themselves
(2) Frequency less than 60mhz
(3) There would be room for physically larger 1-watt metal-oxide
(4) Cost isn't an issue (repair quantities, mostly)
Looking for opinions, of course. I find myself replacing carbon
composition units all the time, and was wondering if metal-oxide would
be "better" than carbon-film for these purposes.
Thanks,
Jim, N7CXI
