Ubuchule Bobugcisa Obucokisekileyo, Obunika Amandla Ikamva: Ii-YMIN TQD42 Series Ultra-Miniature High-Performance Aluminium Electrolytic Capacitors
Kwishishini le-elektroniki elitshintsha ngokukhawuleza namhlanje, ukwenziwa kwezinto zibe ncinci, ukusebenza kakuhle, kunye nokuthembeka kuye kwaba yindlela engenakuguqulwa. Ukusuka kwizixhobo ezinxitywayo ezinobukhulu obufana neminwe ukuya kwizikhululo zonxibelelwano ze-5G ezixineneyo, ukusuka kwi-elektroniki yeemoto ezintsonkothileyo ukuya kwiinkqubo zolawulo ezizinzileyo zemizi-mveliso, yonke indawo ixabisekile, kwaye yonke into eyenzayo ibalulekile.
Ngenxa yesi sizathu, iShanghai YMIN Electronics (YMIN), isebenzisa isiseko sayo sobuchwepheshe esinzulu kunye nolwazi olujonge phambili kwimarike, iqalise uthotho lwe-TQD42 lwee-capacitors ze-aluminium electrolytic ezi-ultra-miniature, low-ESL, ezine-voltage ephezulu. Ngomsebenzi wazo ogqwesileyo kunye noyilo oluncinci, zibonelela iinjineli ngesisombululo esifanelekileyo kwimingeni emibini yendawo kunye nokusebenza.
Eyona nto iphawulekayo kolu luhlu lwe-TQD42 bubungakanani bayo obuncinci kakhulu: 7.3mm (L) × 4.3mm (W) × 4.2mm (H). Olu yilo lwe-"Slim profile" lwenza ukuba ibe lukhetho oluhle kakhulu kwizicelo ezineemfuno ezingqongqo zesithuba se-PCB.
Ukuba ubungakanani obuncinci "bubuhle bangaphandle" be-TQD42, ngoko ukusebenza kwayo okugqwesileyo kombane "ngumphefumlo wayo wangaphakathi." Olu luhlu aluncami ukusebenza ngenxa yobukhulu; endaweni yoko, lufezekisa impumelelo kwizalathisi ezininzi zokusebenza eziphambili ngelixa lugcina i-miniaturization.
I-ESL ephantsi (i-Equivalent Series Inductance), ihlangabezana neemfuno ze-High-Frequency
Ulwakhiwo lwesiphelo esisezantsi ngokwendalo luyayinciphisa indlela ye-current loop, ngaloo ndlela kunciphisa kakhulu i-equivalent series inductance (ESL). Kwiisekethe zedijithali ezinesantya esiphezulu kunye nezixhobo zamandla okutshintsha i-high-frequency (ezifana nee-DC-DC converters), i-ESL ephantsi ithetha ukuba ii-capacitors zinokucoca ingxolo ye-high-frequency kunye ne-ripple current ngokukhawuleza nangokufanelekileyo, ukuqinisekisa ubunyulu kunye nokuzinza kokuphuma kwamandla. Oku kubonelela ngamandla "athuleyo" kwiitships eziphambili ezifana nee-CPU, ii-GPU, kunye nee-ASIC, ukuqinisekisa ukusebenza kwazo okukhawulezayo nokuzinzileyo.
Umthamo ophezulu kunye nobubanzi be-Capacitance, obonelela ngokhetho oluguquguqukayo
Olu luhlu lwe-TQD42 lugubungela uluhlu olubanzi lwe-voltage yokusebenza oluvela kwi-16V ukuya kwi-100V, kunye ne-capacitance eqala kwi-12μF ukuya kwi-470μF. Olu lwazi lubanzi luyivumela ukuba ivumelane nezicelo ezahlukeneyo, ukusuka kwiisekethe ze-logic zedijithali ezine-voltage ephantsi ukuya kwizibonelelo zamandla zoshishino ezine-voltage ephezulu. Nokuba iphatha ibhasi yenkqubo ye-12V, izibonelelo zamandla onxibelelwano ze-48V, okanye iisekethe eziphakathi kwi-electronics yezithuthi zamandla ezintsha, iinjineli zinokufumana imodeli efanelekileyo.
Iimpawu zobushushu obuzinzileyo kunye noyilo lobomi obude
Le mveliso isebenza ngaphakathi kobubanzi bobushushu obuphakathi kwe--55℃ ukuya kwi-+105℃ kwaye ingaqhubeka nokusebenza kubushushu bayo obuphakathi kwe-105℃. Uvavanyo lwayo "lokuqina" lubonisa ukuba emva kweeyure ezingama-2000 zokuguga kumbane olinganiselweyo kunye nobushushu, izinga lokutshintsha kwamandla e-capacitor, i-tangent yokulahleka (tanδ), kunye nomsinga wokuvuza zihlala ngaphakathi kweenkcukacha ezingqongqo. Oku kuqinisekisa ukuthembeka kwemveliso kwiindawo ezinobushushu obuphezulu (ezifana neendawo zeenjini zeemoto kunye nezixhobo zonxibelelwano zangaphandle) kwaye kunciphisa kakhulu umngcipheko wokungaphumeleli kwenkqubo ngenxa yokusilela kwe-capacitor.
Amandla okuphatha iRipple Current anamandla
Enye yemisebenzi ephambili yee-capacitors ekutshintsheni izixhobo zamandla kukuphatha i-ripple current. Uthotho lwe-TQD42 lubonelela ngexabiso elichaziweyo ngokucacileyo le-ripple current (umz., i-2000mA rms kwimodeli ye-100V/12μF kwi-45℃/100kHz) kwaye luxhotyiswe nge-coefficient yobushushu kunye ne-frequency correction factor. Oku kuvumela iinjineli ukuba zibale ngokuchanekileyo i-ripple current esebenzisekayo ye-capacitor ngokusekelwe kwi-frequency yokusebenza kunye ne-ambient temperature, ukuqinisekisa ukuba isebenza ngaphakathi komda wokhuseleko, yandisa ubomi bayo, kwaye iphucula ukusebenza kakuhle kunye nokuthembeka kwenkqubo yonke yonikezelo lwamandla.
