Nto mount capacitors tau tsim rau ntau ntau yam thiab series, cais los ntawm cov duab, qauv thiab kev siv, uas tuaj yeem ncav cuag ntau pua hom.Lawv kuj tseem hu ua chip capacitors, nti capacitors, nrog C ua lub cim sawv cev ntawm lub voj voog.Nyob rau hauv SMT SMD cov kev siv tswv yim, kwv yees li 80% yog rau ntau txheej nti ceramic capacitors, ua raws li nti electrolytic capacitors thiab nti tantalum capacitors, chip organic film capacitors thiab mica capacitors tsawg dua.
1. Chip ceramic capacitor
Chip ceramic capacitors, tseem hu ua chip ceramic capacitors, tsis muaj qhov sib txawv polarity, cov tsos ntawm tib cov duab thiab nti resistors.Lub cev tseem ceeb yog feem ntau grey-daj lossis grey-xim av ceramic substrate, thiab tus naj npawb ntawm cov txheej hauv electrode yog txiav txim siab los ntawm tus nqi capacitance, feem ntau muaj ntau tshaj kaum txheej.
Qhov loj ntawm nti capacitor zoo ib yam li cov nti resistor, muaj 0603, 0805, 1210, 1206 thiab lwm yam.Feem ntau, tsis muaj daim ntawv lo rau ntawm qhov chaw, yog li lub capacitance thiab withstand voltage tus nqi tsis tuaj yeem txawv ntawm lub capacitor nws tus kheej, thiab yuav tsum raug txheeb xyuas los ntawm daim ntawv lo.
2. SMD tantalum capacitor
SMD tantalum capacitor yog hu ua tantalum electrolytic capacitor, uas kuj yog ib hom electrolytic capacitor, tab sis nws siv tantalum hlau li nruab nrab es tsis txhob electrolyte.Ntau lub capacitors nrog lub peev xwm siab hauv ib chav tsev ntim, muaj peev xwm tshaj 0.33F yog tantalum electrolytic capacitors.Nws muaj qhov zoo thiab qhov tsis zoo ntawm qhov sib txawv, thiab nws cov ncej tsis zoo feem ntau yog cim rau ntawm lub cev.Tantalum capacitors muaj peev xwm loj, tsis tshua muaj poob, me me to, lub neej ntev, kub tsis kam, siab raug, thiab zoo heev high zaus filtering kev ua tau zoo.
Cov hom SMD tantalum capacitor yog daj tantalum thiab dub tantalum, pem hauv ntej thiab nraub qaum ntawm SMD daj tantalum capacitor, thiab dub tantalum capacitor.Qhov cim kawg ntawm lub cev tseem ceeb (qhov kawg ntawm daim duab piv txwv) yog lawv cov ncej tsis zoo, thiab peb tus lej cim rau ntawm lub cev tseem ceeb yog tus nqi capacitance qhia los ntawm peb tus lej ntsuas, chav tsev yog PF los ntawm lub neej ntawd, thiab tus nqi voltage sawv cev rau qhov loj ntawm qhov hluav taws xob tsis kam.
3. Chip electrolytic capacitor
Chip electrolytic capacitors yog siv nyob rau hauv ntau yam khoom siv hluav taws xob, thiab pheej yig.Lawv tuaj yeem muab faib ua cov duab plaub electrolytic capacitors (resin encapsulated) thiab cylindrical electrolytic capacitors (hlau encapsulated) raws li cov duab sib txawv thiab cov khoom ntim.Chip electrolytic capacitors feem ntau muaj peev xwm loj dua thiab siv electrolyte li dielectric, qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo polarity yog tib yam li ntawm tantalum capacitors, tab sis tus nqi capacitance feem ntau yog cim rau ntawm nws lub cev tseem ceeb los ntawm txoj kev ncaj nraim, thiab chav tsev. yog μF los ntawm lub neej ntawd.cylindrical nti electrolytic capacitors.
