Tanong ko lang po sana.. meron po bang available na capaciitors na nanoFarad ang unit ng capacitance nya? kasi po wala po talaga akong mahanap dito sa lugar namin..
100nF 63V Polyester or Ceramic Capacitors
22nF 63V Polyester or Ceramic Capacitor
eto po kelangan ko. eto nalang po kulang para masimulan ko project ko. meron po ba nito? at kung wala naman po, ano po bang maari kung maipalit dito? sana po matulungan nyo ako.. TIA

^ sir 100nF = 0.1uF = (104 sa ceramic caps.)
22nF = 0.022uF = (223 sa ceramic caps)
yung 63V kahit 100V pwede jan..
hope makatulong..

thanks sa reply.. meron pala nito. hirap kasi hanapin. isa pa pong tanong, wala po bang kaibahan kung ceramic, mylar o electrolytic gamitin ko? at about po sa voltage, kelangan po ba insaktong 63v o pwede hindi?

saan mo ba gagamitin? pag electrolytic kasi polarize sya. Voltage mas mataas mas ok... magiging bulky nga lang.

ang alam ko tantalum lang ang merong 63V, pero polarized yun.. sa ceramic at mylar naman 50V, 100V etc. may 25 pero bihira.. 63v na ceramic much better 100 na lang gamitin mo walang deperensya yun.. |

104 marking ng 100nf. 223 naman kapag 22nF tapos sunod na marking is voltage rating. Like 63 is 63 volts
