Alarma cu 555

Recommended Posts

Am si eu o nelamurire fata de schema urmatoare: la C1 este specificat 0.047uF polarizat, din cate stiu eu nu exista condensator polarizat asa mic, crezand ca este o greseala am incercat sa il inlocuiesc cu unul ceramic la 33nF apoi 100nF dar nu scotea nici un sunet. Pana la urma am pus unul electrolitic de 2.2uF cu care a inceput sa sune doar ca trosneste probabil la 2.2uF frecventa este mult prea mica. 

 

As vrea sa aflu daca chiar exista condensator polarizat la 47nF ?
