I have just got 5 of these in the mail. I'd like to make a 32.768 khz crystal oscillator, and it looks like I have to wire the resonator to some resistors and capacitors. My question is, if I don't have resistors/capacitors with the correct values (which I don't), is there any reason I can't connect them in combinations of paralell and series to get the resistance and capacitance I need?
