Ama-Surface Mount capacitor asethuthuke aba yizinhlobo eziningi nochungechunge, oluhlukaniswa ngokuma, ukwakheka nokusetshenziswa, olungafinyelela amakhulu ezinhlobo.Abizwa nangokuthi ama-chip capacitor, ama-chip capacitor, no-C njengophawu lokumelela isifunda.Kuzinhlelo zokusebenza ezingokoqobo ze-SMT SMD, cishe amaphesenti angama-80 angawama-multilayer chip ceramic capacitor, alandelwa ama-chip electrolytic capacitor nama-chip tantalum capacitor, ama-chip organic film capacitor nama-mica capacitor mancane.
1. Chip capacitors ceramic
I-chip Ceramic capacitor, eyaziwa nangokuthi i-chip Ceramic capacitors, akukho mehluko we-polarity, ukubukeka komumo ofanayo nezimbangi ze-chip.Umzimba oyinhloko ngokuvamile uyi-substrate ye-ceramic empunga-ophuzi noma empunga ngokunsundu, futhi inani lezendlalelo ze-electrode zangaphakathi linqunywa inani le-capacitance, ngokuvamile kunezendlalelo ezingaphezu kweshumi.
Ubukhulu be-chip capacitor bufana ne-chip resistor, kukhona 0603, 0805, 1210, 1206 njalonjalo.Ngokuvamile, ayikho ilebula ebusweni, ngakho-ke amandla kanye nenani lokumelana ne-voltage akukwazi ukuhlukaniswa ne-capacitor ngokwayo, futhi kufanele kukhonjwe kulebula yephakheji.
2. SMD tantalum capacitors
I-SMD tantalum capacitor ibizwa nge-tantalum electrolytic capacitor, okubuye kube uhlobo olulodwa lwe-electrolytic capacitor, kodwa isebenzisa insimbi ye-tantalum njemaphakathi esikhundleni se-electrolyte.Ama-capacitor amaningi anomthamo omkhulu weyunithi ngayinye, umthamo ongaphezu kuka-0.33F angama-tantalum electrolytic capacitor.Inomehluko we-polarity omuhle kanye nebi, futhi isigxobo sayo esinegethivu sivame ukuphawulwa emzimbeni.Ama-Tantalum capacitor anomthamo omkhulu, ukulahleka okuphansi, ukuvuza okuncane, impilo ende, ukumelana nezinga lokushisa eliphezulu, ukunemba okuphezulu, nokusebenza okuhle kakhulu kokuhlunga imvamisa ephezulu.
Ama-SMD tantalum capacitor ajwayelekile yi-tantalum ephuzi kanye ne-tantalum emnyama, ngaphambili nangemuva kwe-SMD yellow tantalum capacitor, kanye ne-tantalum capacitor emnyama.Isiphetho esimakiwe emzimbeni oyinhloko (umkhawulo ongaphezulu esithombeni esiyisibonelo) uyisigxobo sawo esingesihle, futhi izinombolo ezintathu ezimakwe emzimbeni omkhulu ziyinani lamandla eliboniswa indlela yesikali samadijithi amathathu, iyunithi i-PF ngokuzenzakalelayo, futhi inani le-voltage limelela inani lobukhulu bokumelana ne-voltage.
3. Chip electrolytic capacitors
Ama-chip electrolytic capacitor asetshenziswa kakhulu emikhiqizweni ehlukahlukene yabathengi, futhi ayabizi.Angahlukaniswa ngama-capacitor e-electrolytic angama-resin (i-resin encapsulated) kanye nama-cylindrical electrolytic capacitors (insimbi ehlanganisiwe) ngokusho kobumo obuhlukene nezinto zokupakisha.Ama-Chip electrolytic capacitor ngokuvamile anomthamo omkhulu futhi asebenzisa i-electrolyte njenge-dielectric, umehluko phakathi kwe-polarity enhle nengalungile uyafana nowe-tantalum capacitor, kodwa usayizi we-capacitance value ngokuvamile umakwa emzimbeni wawo oyinhloko ngendlela yelebula eqondile, kanye neyunithi. ingu-μF ngokuzenzakalelayo.I-cylindrical chip electrolytic capacitors.
