I-Surface Mount capacitors iye yaphuhliswa yaba ziindidi ezininzi kunye nothotho, zihlelwa ngokwemilo, ukwakheka kunye nokusetyenziswa, ezinokufikelela kumakhulu eentlobo.Zikwabizwa ngokuba zii-chip capacitors, ii-chip capacitors, kunye no-C njengophawu lokumelwa kwesekethe.Kwizicelo ezisebenzayo ze-SMT SMD, malunga ne-80% ye-multilayer chip ceramic capacitors, ilandelwa yi-chip electrolytic capacitors kunye ne-chip tantalum capacitors, i-chip organic film capacitors kunye ne-mica capacitors zincinci.
1. Chip capacitors ceramic
I-Chip ceramic capacitors, eyaziwa ngokuba yi-chip ceramic capacitors, akukho mahluko we-polarity, imbonakalo yesimo esifanayo kunye nezixhasi ze-chip.Umzimba oyintloko ngokuqhelekileyo u-gray-yellow okanye i-gray-brown ceramic substrate, kwaye inani leeleyile ze-electrode zangaphakathi lichongwa ngexabiso le-capacitance, ngokubanzi kukho ngaphezu kweshumi.
Ubungakanani be-chip capacitor bufana ne-chip resistor, kukho i-0603, i-0805, i-1210, i-1206 njalo njalo.Ngokuqhelekileyo, akukho ileyibhile phezu komhlaba, ngoko ke i-capacitance kunye nokumelana nexabiso le-voltage ayikwazi ukwahlula kwi-capacitor ngokwayo, kwaye kufuneka ichongwe kwileyibhile yephakheji.
2. SMD tantalum capacitors
I-SMD tantalum capacitor ibizwa ngokuba yi-tantalum electrolytic capacitor, ekwaluhlobo olunye lwe-electrolytic capacitor, kodwa isebenzisa intsimbi ye-tantalum njengendawo ephakathi endaweni ye-electrolyte.Iicapacitors ezininzi ezinomthamo ophezulu weyunithi nganye, umthamo ongaphezulu kwe-0.33F yi-tantalum electrolytic capacitors.Inomahluko oqinisekileyo kunye nobubi be-polarity, kwaye ipali yayo engalunganga idla ngokuphawulwa emzimbeni.I-Tantalum capacitors inomthamo ophezulu, ilahleko ephantsi, ukuvuza okuncinci, ubomi obude, ukumelana nobushushu obuphezulu, ukuchaneka okuphezulu, kunye nokusebenza okuphezulu kokucoca amaza.
I-SMD tantalum capacitors eziqhelekileyo ziyi-yellow tantalum kunye ne-tantalum emnyama, ngaphambili nangasemva kwe-SMD yellow tantalum capacitor, kunye ne-tantalum capacitor emnyama.Isiphelo esiphawulweyo kumzimba oyintloko (isiphelo esiphezulu kumfanekiso womzekelo) sisibonda sabo esibi, kwaye amanani amathathu aphawulwe kumzimba oyintloko yixabiso le-capacitance elibonakaliswe yindlela yokulinganisa amanani amathathu, iyunithi i-PF ngokungagqibekanga, kunye nexabiso lombane limele ixabiso lobungakanani bokumelana nombane.
3. I-chip electrolytic capacitors
I-chip electrolytic capacitors zisetyenziswa ikakhulu kwiimveliso ezahlukeneyo zombane zabathengi, kwaye azibizi.Ziyakwazi ukwahlula kwii-capacitors ze-electrolytic ezixande (i-resin encapsulated) kunye ne-cylindrical electrolytic capacitors (i-metal encapsulated) ngokwemilo eyahlukeneyo kunye nezinto zokupakisha.I-Chip electrolytic capacitors ngokubanzi inomthamo omkhulu kwaye isebenzisa i-electrolyte njenge-dielectric, umahluko phakathi kwe-polarity elungileyo kunye nengalunganga iyafana naleyo ye-tantalum capacitors, kodwa ubungakanani bexabiso le-capacitance buphawulwa ngokubanzi kumzimba wayo oyintloko ngendlela yeleyibhile ethe tye, kunye neyunithi. ngu μF ngokungagqibekanga.cylindrical chip electrolytic capacitors.
