Xajiyeyaasha dusha sare waxay u soo baxeen noocyo iyo taxane badan, oo loo kala saaray qaabka, qaab-dhismeedka iyo isticmaalka, kuwaas oo gaari kara boqolaal nooc.Waxa kale oo loo yaqaan capacitors chip, capacitors chip, oo leh C oo ah calaamada matalida wareegga.Codsiyada wax ku oolka ah ee SMT SMD, qiyaastii 80% waxay ka tirsan yihiin capacitors chip ceramic capacitors, oo ay ku xigto capacitors chip electrolytic capacitors iyo chip tantalum capacitors, capacitors film organic chip iyo capacitors mica ayaa ka yar.
1. Chip ceramic capacitors
Chip ceramic capacitors, oo sidoo kale loo yaqaan capacitors-ceramic capacitors, ma jiro farqi u dhexeeya polarity, muuqaalka qaab isku mid ah iyo caabiyeyaasha chip.Jirka ugu weyn guud ahaan waa substrate dhoobada cawl-jaalle ama cawl-brown, iyo tirada lakabyada electrode gudaha waxaa lagu go'aamiyaa qiimaha capacitance, guud ahaan waxaa jira in ka badan toban lakab.
Cabbirka capacitor-ka chip wuxuu la mid yahay kan chip resistor, waxaa jira 0603, 0805, 1210, 1206 iyo wixii la mid ah.Guud ahaan, ma jiraan wax calaamad ah oo dusha sare ah, sidaas darteed awoodda awoodda iyo u adkaysiga qiimaha korantada lama kala saari karo capacitor laftiisa, waana in laga gartaa calaamadda xirmada.
2. SMD tantalum capacitors
SMD tantalum capacitor waxaa lagu magacaabaa tantalum electrolytic capacitor, kaas oo sidoo kale ah nooc ka mid ah capacitor electrolytic, laakiin waxa ay isticmaashaa birta tantalum sida dhexdhexaad ah halkii ay ka isticmaali lahayd electrolyte.Capacitors badan oo leh awood sare halkii mugga, awoodda ka badan 0.33F waa capacitors tantalum electrolytic.Waxay leedahay kala soocis togan iyo mid taban, tiirkeeda taban badanaa waxay ku calaamadsan tahay jirka.Tantalum capacitors waxay leeyihiin awood sare, khasaaro hoose, daadinta yar, cimri dheer, caabbinta heerkulka sare, saxnaanta sare, iyo waxqabadka shaandhaynta soo noqnoqda sare ee aad u fiican.
Xirmooyinka tantalum ee SMD ee caadiga ah waa tantalum jaalaha ah iyo tantalum madow, hore iyo gadaal ee SMD capacitor jaalaha ah, iyo capacitor tantalum madow.Dhamaadka calaamadeysan ee jirka ugu weyn (cirifka sare ee sawirka tusaalaha) waa cirifkooda taban, iyo saddexda lambar ee ku calaamadsan jirka weyn waa qiimaha awoodda ee lagu tilmaamay habka cabbirka saddex-god, cutubku waa PF by default, iyo qiimaha danabku waxa uu ka dhigan yahay baaxadda qiimaha caabbinta danab.
3. Chip electrolytic capacitors
Qalabka korontada ku shaqeeya ee loo yaqaan 'chip electrolytic capacitors' waxaa inta badan loo adeegsadaa alaabada elektiroonigga ah ee macaamiisha kala duwan, waana qaali.Waxa loo qaybin karaa afar xagal korantada capacitors (resin encapsulated) iyo capacitors cylindrical electrolytic capacitors (biraha la daboolay) iyadoo loo eegayo qaabab kala duwan iyo alaabta baakadaha.Chip electrolytic capacitors guud ahaan waxay leeyihiin awood weyn oo ay isticmaalaan electrolyte sida dielectric, farqiga u dhexeeya polarity togan iyo taban waa la mid ah tan capacitors tantalum, laakiin size capacitance qiimaha guud ahaan waxaa lagu calaamadeeyay jirkeeda ugu weyn habka sumadda toosan, iyo cutubka waa μF defaultcylindrical chip electrolytic capacitors.
