ICapacitor iyingxenye eyisisekelo ebalulekile emibukeni ye-elekthronikhi.Umsebenzi wayo oyinhloko ukugcina nokukhipha amandla kagesi.Lapho i-voltage isetshenziswa ngaphesheya kwe-capacitor, ithola amandla avela emthonjeni futhi igcina insimu kagesi eyenziwe phakathi kwamapuleti.Ngakolunye uhlangothi, lapho i-voltage iwela i-capacitor yehla, kukhishwe amandla kagesi agcinwe endle.Ekukhiqizeni nokulungiswa kwe-elekthronikhi, ama-capacitors asetshenziswa kabanzi, alandelwa kuphela ngabaphikisi.Imvamisa isetshenziselwa imisebenzi efana nokuhlanganisa umjikelezo, ukuhlunga, ukuhlukaniswa kwe-DC kanye nomthethonqubo, futhi kungahlanganiswa nezinto ezingenisa izingxenye zokwakha umjikelezo we-oscillation.Ukuze usize abathanda i-elekthronikhi kanye nonjiniyela baqonde kangcono futhi basebenzise ama-capacitors, le ndatshana izogxila kwindlela yokulebula ye-capacitors kanye nesicelo sabo emijikelezo ye-elekthronikhi.
Izindlela zokulebula zeCapacitor zihlukaniswe izigaba ezimbili: indlela eqondile yokulebula kanye nendlela yokulebula engaqondile.
1. Indlela yokulebula eqondile
Le ndlela ikhomba i-capacitor ngokumaka amandla ngqo kuleli cala.Amazinga ephutha lale ndlela yelebula avame ukuhlukaniswa ngamazinga amahlanu: 00, 0, i, ii, no-III ngokulandelana amaphutha ka- ± 1%, ± 5%, kanye ± 20%.Uma izinga lephutha lingamakwa ngokuqondile, iphutha elizenzakalelayo liyi- ± 20%.Indlela ethile yelebula ilandela kanjena:
.Isibonelo, i-Picofarad Capacitor engama-47 ibhalwe ngo-47p, i-10 nanofard capacitor ibhalwe nge-10n, futhi i-microfarad casacitor ebhalwe yi-100μf.
(2) Sebenzisa amayunithi esikhundleni samaphoyinti wedesimali: Isibonelo, ama-microfarads angama-2.2 angamakwa njengo-2μ2, 2.2 Picofarads njenge-2p2, 2.2 Nanofarads njenge-2N2, njll.
.Isibonelo, i-microfarad capacitor engu-0.47 ilebula u-R47, kanye ne-microfarad capacitor ebhalwe ngu-R22.
.Isibonelo, i-Picofarad Capacitor engama-5100 imakwe njengengama-5100, i-Picofarad Capacitor engama-51 imakwe njengo-51;I-capacitor ye-microfarad ye-0.047 imakwe njenge-0.047, i-microfarad capacitor ebhalwe njengo-0.01, njll.
2. Indlela enamadijithi amathathu aqondile
Le ndlela yokumaka ivame kakhulu kuma-capacitors amancane, ikakhulukazi lawo anomthamo ongaphansi kwe-microfarad.Ngale ndlela, inombolo enamadijithi amathathu ayimele ngokuqondile amandla e-capacitor, kepha ilinganiswa ePicofarads (PF), futhi iphutha livame ukuvezwa ngezinhlamvu.Phakathi kwazo, amadijithi amabili okuqala amele inombolo eyisisekelo, kanti nenombolo yesithathu imelela ukukhulisa.Ifomula yokubala inani le-capacitance yile: Masip × Magnation.Isibonelo, i-capacitor emakwe ngu-222 inesikhundla esibalwa njenge-22 × 102 = 2200 Picofarads;Ngenkathi i-capacitor imakwe ngu-104 inomthamo we-10 × 104 = 100000 Picofarads, okungukuthi ama-microfararads angu-0,1.Kumele kuqashelwe ukuthi kwezinye izimo, kungahle kube nokudideka phakathi kwendlela yokumaka enamadijithi amathathu kanye nendlela eqondile yokumaka yasekhaya.Isibonelo, ama-Picofarads angama-510 asekhaya angamakwa njengo-510, ngenkathi kwakwamanye amazwe angahle amele ama-Picofarads angama-51.
Ukuqonda lezi zindlela zokumaka kwama-capacitors kubalulekile kunjiniyela be-elekthronikhi nabathandi.Akusizi kuphela ekukhetheni okulungile kwama-capacitors, kepha futhi nasekwakhiweni kwesifunda nokuxilongwa amaphutha.
ulwazi oluyisisekelo.Ukukhonjwa kwesichasiselo esifanele kungaqinisekisa ukusebenza okujwayelekile kwesifunda nokwandisa ukusebenza.
