Surface Mount capacitors akagadzira akawanda marudzi uye akateedzana, akakamurwa nechimiro, chimiro uye mashandisiro, ayo anogona kusvika mazana emhando.Ivo vanonzi zvakare chip capacitors, chip capacitors, ine C sechiratidzo chekumiririra redunhu.MuSMT SMD inoshanda maapplication, ingangoita makumi masere muzana ndeye multilayer chip ceramic capacitors, ichiteverwa ne chip electrolytic capacitors uye chip tantalum capacitors, chip organic film capacitors uye mica capacitors zvishoma.
1. Chip ceramic capacitors
Chip ceramic capacitors, inozivikanwawo se chip ceramic capacitors, hapana polarity musiyano, kutaridzika kwechimiro chimwe chete uye chip resistors.Muviri mukuru unowanzo grey-yero kana grey-brown ceramic substrate, uye huwandu hwemukati maelectrode layers inotarwa necapacitance kukosha, kazhinji kune anopfuura gumi akaturikidzana.
Saizi ye chip capacitor yakafanana neye chip resistor, pane 0603, 0805, 1210, 1206 zvichingodaro.Kazhinji, hapana chinyorwa pamusoro, saka iyo capacitance uye inomira kukosha kwevoltage haigone kusiyaniswa kubva kune capacitor pachayo, uye inofanirwa kucherechedzwa kubva papakiti label.
2. SMD tantalum capacitors
SMD tantalum capacitor inonzi tantalum electrolytic capacitor, inovawo imwe mhando ye electrolytic capacitor, asi inoshandisa tantalum simbi sepakati pane electrolyte.Mazhinji macapacitor ane huwandu hwepamusoro pavhoriyamu yeyuniti, huwandu hunopfuura 0.33F ndeye tantalum electrolytic capacitors.Iyo ine yakanaka uye isina kunaka polarity distinction, uye danda rayo rakashata rinowanzoiswa chiratidzo pamuviri.Tantalum capacitors ine hukuru hwepamusoro, kurasikirwa kwakaderera, kudonha kudiki, hupenyu hwakareba, yakanyanya tembiricha kuramba, kurongeka kwepamusoro, uye yakanakisa yakakwirira frequency kusefa kuita.
Iyo yakajairwa SMD tantalum capacitor ndeyero tantalum uye dema tantalum, kumberi nekumashure kweSMD yero tantalum capacitor, uye nhema tantalum capacitor.Mugumo wakatarwa pamutumbi mukuru (yekumusoro kumagumo mumufananidzo wemuenzaniso) ndiro danda rawo rakashata, uye nhamba nhatu dzakatarwa pamutumbi mukuru ndiko kukosha kwecapacitance kunoratidzwa nenzira yechiyero-matatu, iyo unit iPF nekusingaperi, uye kukosha kwevoltage kunomiririra kukosha kwehukuru hwekupikisa voltage.
3. Chip electrolytic capacitors
Chip electrolytic capacitors inonyanya kushandiswa mune zvakasiyana-siyana zvemagetsi zvigadzirwa, uye zvisingadhure.Ivo vanogona kukamurwa kuita rectangular electrolytic capacitors (resin yakavharidzirwa) uye cylindrical electrolytic capacitors (simbi yakavharidzirwa) zvichienderana nemhando dzakasiyana uye yekurongedza zvinhu.Chip electrolytic capacitors inowanzova nehukuru hwakakura uye inoshandisa electrolyte se dielectric, mutsauko uripo pakati pechakanaka nechakaipa polarity wakafanana neiyo yetantalum capacitors, asi saizi yehukudzo hunowanzo kucherechedzwa pamutumbi wayo mukuru nenzira yakatwasuka, uye chikamu. iri μF nekukasira.cylindrical chip electrolytic capacitors.
