tago Posted December 2, 2016 Report Share Posted December 2, 2016 Can i use cheap carbon film resistors for NG boards (CoreSTM32, AINSER, DIO Matrix ...)? It says carbon film resistors are more noisy and i don't know if they add noise to a Midibox system. Should i use 0,6 1% metal resistors instead of 1/4W 5% carbon film ones?

tago Posted December 2, 2016 Author Report Share Posted December 2, 2016 I ordered my resistors at Reichelt and used the uCApps orderlists. The orderlists part# results in carbon film resistors, but i see blue (metal?) resistors on the soldering guide photos. Quote Link to comment Share on other sites More sharing options...
latigid on Posted December 2, 2016 Report Share Posted December 2, 2016 No problem with carbon, especially when they're pull ups/current limiting. Maybe an issue for analogue or where Tc becomes important. But even in AINSER, your pots will be carbon film. Metal used to be much more $$, now they can even work out cheaper.

tago Posted December 2, 2016 Author Report Share Posted December 2, 2016 Thanks @latigid on AINSER is my main concern, i thought it could add up noise. Quote Link to comment Share on other sites More sharing options...
latigid on Posted December 2, 2016 Report Share Posted December 2, 2016 For AINSER64 you have the choice of a regulated power supply, then the only resistors in circuit are to current limit the LEDs. Notice the filter caps on the ADC Vref . Quote Link to comment Share on other sites More sharing options...
