Li-Capacitor tsa Surface Mount li se li fetohile mefuta e mengata le letoto, li arotsoe ka sebopeho, sebopeho le ts'ebeliso, tse ka fihlelang makholo a mefuta.Li boetse li bitsoa chip capacitors, chip capacitors, le C e le letšoao la boemeli ba potoloho.Lits'ebetsong tse sebetsang tsa SMT SMD, hoo e ka bang 80% ke tsa li-multilayer chip ceramic capacitor, tse lateloang ke chip electrolytic capacitor le chip tantalum capacitor, chip organic film capacitor le mica capacitor li tlase.
1. Chip ceramic capacitors
Li-capacitor tsa chip ceramic, tse tsejoang hape e le chip ceramic capacitors, ha ho na phapang ea polarity, ponahalo ea sebopeho se tšoanang le li-resistors tsa chip.'Mele o ka sehloohong ka kakaretso ke substrate ea ceramic e bohlooho-bosehla kapa bohlooho-sootho,' me palo ea likarolo tsa ka hare tsa li-electrode li khethoa ke boleng ba capacitance, ka kakaretso ho na le lihlopha tse fetang leshome.
Boholo ba chip capacitor bo tšoana le ba chip resistor, ho na le 0603, 0805, 1210, 1206 joalo-joalo.Ka kakaretso, ha ho na label holim'a metsi, kahoo matla le boleng ba motlakase bo ke keng ba khetholloa ho capacitor ka boeona, 'me e tlameha ho khetholloa ho tloha lebokoseng la sephutheloana.
2. SMD tantalum capacitors
SMD tantalum capacitor e bitsoa tantalum electrolytic capacitor, eo hape e leng mofuta o le mong oa electrolytic capacitor, empa e sebelisa tšepe ea tantalum joalo ka mahareng ho fapana le electrolyte.Li-capacitor tse ngata tse nang le bokhoni bo phahameng ka bophahamo ba yuniti, matla a fetang 0.33F ke li-capacitor tsa tantalum electrolytic.E na le phapang e ntle le e mpe ea polarity, 'me palo ea eona e mpe hangata e tšoauoa' meleng.Li-capacitor tsa Tantalum li na le bokhoni bo phahameng, tahlehelo e tlase, ho lutla hanyane, bophelo bo bolelele, ho hanyetsa mocheso o phahameng, ho nepahala ho phahameng, le ts'ebetso e ntle haholo ea ho sefa khafetsa.
Li-capacitor tse tloaelehileng tsa SMD tantalum ke tantalum e mosehla le tantalum e ntšo, ka pele le ka morao ho SMD yellow tantalum capacitor, le black tantalum capacitor.Qetello e tšoailoeng holim'a 'mele o ka sehloohong (qetellong e ka holimo setšoantšong sa mohlala) ke palo ea bona e mpe,' me linomoro tse tharo tse tšoailoeng 'meleng o ka sehloohong ke boleng ba bokhoni bo bontšitsoeng ke mokhoa oa litekanyetso tse tharo, yuniti ke PF ka ho feletseng, 'me boleng ba motlakase bo emela boleng ba boholo ba ho hanyetsa motlakase.
3. Chip electrolytic capacitors
Li-capacitor tsa chip electrolytic li sebelisoa haholo lihlahisoa tse fapaneng tsa elektroniki tsa bareki, 'me ha li theko e tlase.Li ka aroloa ka li-capacitor tsa electrolytic capacitor (resin encapsulated) le cylindrical electrolytic capacitors (metal encapsulated) ho latela libopeho tse fapaneng le thepa ea ho paka.Chip electrolytic capacitor ka kakaretso e na le bokhoni bo boholo mme e sebelisa electrolyte joalo ka dielectric, phapang lipakeng tsa polarity e ntle le e mpe e ts'oana le ea tantalum capacitor, empa boholo ba boleng ba capacitance hangata bo tšoauoa 'meleng oa eona ka mokhoa o otlolohileng oa label, le yuniti. ke μF ka ho sa feleng.cylindrical chip electrolytic capacitors.
