1. Chip yumbu capacitors
Chip yumbu capacitors, wanda kuma aka sani da guntu ceramic capacitors, babu bambancin polarity, bayyanar siffa iri ɗaya da masu adawa da guntu.Babban jiki gabaɗaya shine launin toka-rawaya ko launin toka-kasa-kasa yumbura, kuma adadin yadudduka na cikin lantarki ana ƙaddara ta ƙimar ƙarfin, gabaɗaya akwai fiye da yadudduka goma.
Girman capacitor capacitor yayi kama da na chip resistor, akwai 0603, 0805, 1210, 1206 da sauransu.Gabaɗaya, babu lakabin a saman, don haka ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin da ƙarfin ƙarfin da kansa, kuma dole ne a gano shi daga alamar fakitin.
2. SMD tantalum capacitors
SMD tantalum capacitor ana kiransa tantalum electrolytic capacitor, wanda kuma shine nau'in capacitor na electrolytic, amma yana amfani da tantalum karfe a matsayin matsakaici maimakon electrolyte.Yawancin capacitors tare da babban ƙarfin kowace juzu'in naúrar, ƙarfin sama da 0.33F sune masu ƙarfin lantarki na tantalum electrolytic.Yana da bambance-bambancen polarity mai kyau da mara kyau, kuma mummunan sandarsa yawanci ana alama a jiki.Tantalum capacitors suna da babban iya aiki, ƙarancin asara, ƙaramin ɗigo, tsawon rai, juriya mai zafi, babban daidaito, da ingantaccen aikin tacewa mai yawa.
SMD na yau da kullun tantalum capacitors sune rawaya tantalum da tantalum baƙar fata, gaba da baya na SMD yellow tantalum capacitor, da baƙar fata tantalum capacitor.Ƙarshen da aka yi alama akan babban jiki (ƙarshen babba a cikin hoton misali) shine sandar su mara kyau, kuma lambobi uku da aka yiwa alama akan babban jiki sune ƙimar ƙarfin da aka nuna ta hanyar sikelin lambobi uku, naúrar ita ce PF ta tsohuwa, kuma ƙimar ƙarfin lantarki tana wakiltar girman ƙimar ƙarfin ƙarfin lantarki.
3. Chip electrolytic capacitors
Chip electrolytic capacitors ana amfani da su a cikin samfuran lantarki daban-daban, kuma ba su da tsada.Ana iya raba su zuwa capacitors na electrolytic rectangular (resin encapsulated) da cylindrical electrolytic capacitors (karfe encapsulated) bisa ga siffofi daban-daban da kayan tattarawa.Chip electrolytic capacitors gabaɗaya suna da girma girma da kuma amfani da electrolyte a matsayin dielectric, da bambanci tsakanin tabbatacce da kuma korau polarity ne iri daya da na tantalum capacitors, amma capacitance darajar size ne kullum alama a kan babban jiki ta madaidaiciyar lakabin hanya, da naúrar. shine μF ta tsohuwa.cylindrical guntu electrolytic capacitors.
