Ibisobanuro by'ibicuruzwa
Ubukorikori bwimbitse, butanga imbaraga mu gihe kizaza: YMIN TQD42 Series Ultra-Miniature High-Performance Aluminium Electrolytic Capacitors
Mu nganda z'ikoranabuhanga zigenda zitera imbere vuba muri iki gihe, gukora ibintu mu buryo buciriritse, gukora neza no kwizerwa byabaye ibintu bidasanzwe. Kuva ku bikoresho byambarwa binini kugeza ku bikoresho by'itumanaho bya 5G bifite imbaraga nyinshi, kuva ku bikoresho by'ikoranabuhanga bigezweho by'imodoka kugeza ku buryo buhamye bwo kugenzura ibikoresho by'inganda, buri santimetero imwe ni ingenzi, kandi buri ntambwe yose yo gukora ni ingenzi.
Muri iki kibazo, Shanghai YMIN Electronics (YMIN), ikoresheje ikoranabuhanga ryayo ryimbitse n'ubumenyi bw'isoko ry'ejo hazaza, yatangije uruhererekane rwa TQD42 rwa capacitors za aluminium electrolytic capacitors ntoya cyane, ESL nke, zifite voltage nyinshi. Kubera imikorere yazo ihebuje n'igishushanyo mbonera gito, baha injeniyeri igisubizo cyiza ku bibazo bibiri by'ikirere n'imikorere.
Ikintu gitangaje cyane muri uru ruhererekane rwa TQD42 ni ingano yayo nto cyane: 7.3mm (L) × 4.3mm (W) × 4.2mm (H). Iyi miterere ya "Slim profile" ituma iba amahitamo meza cyane ku bikoresho bifite umwanya ukomeye wa PCB.
Niba ingano nto ari "ubwiza bwo hanze" bwa TQD42, noneho imikorere yayo itangaje y'amashanyarazi ni "ubugingo bwayo bw'imbere." Uru ruhererekane ntirugira ingaruka ku bunini bw'imikorere; ahubwo rugera ku ntambwe nyinshi mu bipimo by'ingenzi by'imikorere mu gihe rukomeza kuba ruto.
ESL yo hasi (Equivalent Series Inductance), yujuje ibisabwa ku bwinshi
Imiterere y'aho amashanyarazi aherereye hasi mu buryo busanzwe igabanya inzira y'ubushyuhe, bityo bigabanyiriza cyane uburyo bwo gukwirakwiza ingufu (ESL). Mu miyoboro ya digitale yihuta cyane no mu bikoresho by'amashanyarazi bihindagurika cyane (nk'abahindura DC-DC), ESL nkeya bivuze ko capacitors zishobora gushungura urusaku rw'ubushyuhe n'umuyoboro w'amashanyarazi wihuta cyane kandi neza, bikerekana ubuziranenge n'ituze ry'ingufu. Ibi bitanga imbaraga "zituje" kuri chips zo mu gice cya mbere nka CPU, GPU, na ASIC, bikerekana ko zikora neza kandi zihamye.
Ingufu nyinshi n'ubushobozi bunini, bitanga amahitamo yoroshye
Uruhererekane rwa TQD42 rukubiyemo urwego runini rw'amashanyarazi rukoreshwa kuva kuri 16V kugeza 100V, rufite ubushobozi kuva kuri 12μF kugeza kuri 470μF. Ubu buryo bugari butuma rushobora guhuza n'uburyo butandukanye bwo gukoresha, kuva ku miyoboro ya digitale ifite voltage nkeya kugeza ku ngufu z'inganda zifite voltage nyinshi. Baba bakoresha bisi ya sisitemu ya 12V, ingufu z'itumanaho za 48V, cyangwa imiyoboro y'amashanyarazi mu bikoresho bishya by'ikoranabuhanga, abahanga bashobora kubona icyitegererezo gikwiye.
Ibiranga ubushyuhe buhamye n'igishushanyo mbonera cy'igihe kirekire cyo kubaho
Iki gicuruzwa gikora mu bushyuhe buri hagati ya -55℃ na +105℃ kandi gishobora gukomeza gukora ku bushyuhe bwacyo buri hagati ya 105℃. Isuzuma ryacyo "rirambye" ryerekana ko nyuma y'amasaha 2000 yo gusaza ku muvuduko n'ubushyuhe byagenwe, igipimo cy'impinduka mu bushobozi bwa capacitor, igihombo cya tangent (tanδ), n'umuvuduko w'amazi biguma mu buryo buhamye. Ibi byemeza ko iki gicuruzwa kidahinduka mu bushyuhe bwinshi (nk'aho moteri z'imodoka ziherereye n'ibikoresho by'itumanaho byo hanze) kandi bigabanya cyane ibyago byo kwangirika kwa sisitemu bitewe n'impinduka mu bushobozi bwa capacitor.
Ubushobozi bukomeye bwo gucunga umuyoboro w'amazi utemba
Imwe mu nshingano z'ingenzi za capacitors mu guhinduranya ingufu ni ugukoresha umuvuduko w'amashanyarazi. Uruhererekane rwa TQD42 rutanga agaciro k'umuvuduko w'amashanyarazi usobanutse neza (urugero, 2000mA rms kuri moderi ya 100V/12μF kuri 45℃/100kHz) kandi rufite coefficient y'ubushyuhe n'igipimo cyo gukosora frequency. Ibi bituma abahanga mu by'imashini babara neza umuvuduko w'amashanyarazi ukoreshwa wa capacitor hashingiwe ku muvuduko nyawo w'imikorere n'ubushyuhe bw'ikirere, bakareba ko ikora mu buryo burambye, yongere igihe cyayo cyo kubaho, kandi inongera imikorere myiza n'ubwirinzi bwa sisitemu yose y'amashanyarazi.
Isesengura ryimbitse ry'ishyirwa mu bikorwa ry'ibintu bifatika
Ibi biranga uruhererekane rwa TQD42 bituma rugaragara mu nzego nyinshi:
• Ibikoresho by'itumanaho: Mu mashanyarazi ya sitasiyo za 5G, switches za network, na routers, ikoreshwa mu gushungura input/output. Imiterere yayo ya ESL nke n'imiterere yayo ya frequency yo hejuru bigabanya neza urusaku rwo guhinduranya frequency yo hejuru, bigatuma ubutumwa bw'amajwi bukomeza kuba bwiza.
• Ibyuma by'ikoranabuhanga by'imodoka: Mu byuma bitanga ingufu bya ADAS (Advanced Driver Assistance Systems), sisitemu zo gukwirakwiza amakuru mu modoka, na ECU (Electronic Control Units), ubushyuhe bwayo bunini n'imiterere yayo y'igihe kirekire bishobora kwihanganira imikorere mibi y'ibikoresho by'ikoranabuhanga by'imodoka, bigatuma habaho umutekano mu gutwara imodoka.
• Igenzura ry’inganda n’uburyo bwikora: Muri PLC (Programmable Logic Controllers), servo drives, na robots zo mu nganda, itanga imbaraga zihamye kandi zisukuye ku nsinga z’ubuyobozi zigenzura, irwanya uburyo butandukanye bwo kubangamira amashanyarazi mu nganda kandi ikubahiriza uburyo bwo gukora neza no gukomeza.
• Ibyuma by'ikoranabuhanga bikoreshwa n'abaguzi: Mu bikoresho bya VRM by'amakarita y'amashusho yo ku rwego rwo hejuru, motherboard za mudasobwa zigendanwa ziciriritse cyane, na adaptateri z'amashanyarazi ku bikoresho byo mu rugo bigezweho, imiterere mito n'ubwizerwe buhanitse ni ingenzi mu kwemeza imikorere y'ibicuruzwa n'uburambe bw'ababikoresha.
Umwanzuro
Uruhererekane rwa YMIN TQD42 rwa capacitors za aluminium ntoya cyane ni uruhurirane rwiza rw'ubuhanga mu by'ubuhanga n'ibikenewe ku isoko. Bitewe n'imiterere yarwo yihariye ya "ingano nto, ESL nke, voltage ikomeye yo kwihanganira, no kwizerwa cyane," rukemura neza ibibazo by'ingenzi mu miterere y'ibikoresho by'ikoranabuhanga bigezweho. Guhitamo TQD42 si uguhitamo gusa igice cyiza cy'ikoranabuhanga, ahubwo ni no guhitamo umufatanyabikorwa wiringirwa ufasha ibicuruzwa byawe kugaragara neza mu ipiganwa rikomeye ku isoko no gutsinda ejo hazaza. Mu nzira igana ku isi y'ikoranabuhanga igezweho, ikora neza kandi ihujwe, capacitors za YMIN TQD42 zabaye igikoresho cy'ingenzi mu maboko y'abahanga.
