Iyo usobanukiwe nubushobozi, kimwe mubintu byingenzi ugomba gusuzuma ni ESR (irwanya urukurikirane ruringaniye). ESR ni ikintu kiranga ubushobozi bwose kandi kigira uruhare runini muguhitamo imikorere yabo muri rusange. Muri iyi ngingo, tuzasesengura isano iri hagati ya ESR na capacator, twibanze cyane cyanehasi-ESR MLCCs(ubushobozi bwa ceramic capacator).
ESR irashobora gusobanurwa nkurwanya rubaho rukurikiranye hamwe nubushobozi bwa capacitor kubera imyitwarire idahwitse yibintu bya capacitor. Irashobora gutekerezwa nkurwanya rugabanya umuvuduko wumuyaga unyuze muri capacitor. ESR ni ikintu kitifuzwa kuko gitera ingufu gukwirakwizwa nkubushyuhe, bityo bikagabanya imikorere ya capacitor kandi bikagira ingaruka kumikorere.
None, ni izihe ngaruka ESR igira kuri capacator? Reka ducukumbure birambuye.
1. Gukwirakwiza ingufu: Iyo amashanyarazi anyuze muri capacitor, ingufu zitakara muburyo bwubushyuhe bitewe nuburwanya butangwa na ESR. Uku gukwirakwiza imbaraga kurashobora gutuma ubushyuhe bwiyongera, bushobora kugira ingaruka mbi kumikorere rusange nubuzima bwa serivisi ya capacitor. Kubwibyo, kugabanya ESR ningirakamaro kugirango ugabanye igihombo cyamashanyarazi no gukora neza imikorere ya capacitor.
2. Umuvuduko w'amashanyarazi: Mubisabwa aho capacator zikoreshwa mugushungura no koroshya intego, ESR ihinduka ikintu gikomeye. ESR itanga imbaraga za voltage cyangwa ihindagurika iyo voltage hejuru ya capacitor ihinduka vuba. Izi mpanuka zirashobora gutera uruzinduko rwumuzunguruko no kugoreka, bigira ingaruka kumiterere yikimenyetso gisohoka. Ubushobozi buke bwa ESR bwashizweho kugirango hagabanuke kugabanya ingufu za voltage no gutanga imirongo ihamye.
3. Guhindura umuvuduko: Ubushobozi bukoreshwa mumashanyarazi ya elegitoronike arimo ibikorwa byo guhinduranya byihuse. ESR yo hejuru irashobora kugabanya umuvuduko mwinshi wumuzunguruko, bigatera gutinda no kugabanya imikorere myiza. Ubushobozi buke bwa ESR, kurundi ruhande, butanga ibiciro byihuse kandi bisohoka, bigatuma biba byiza kubisabwa bisaba guhinduranya byihuse.
4. Igisubizo cyinshyi: ESR nayo igira ingaruka zikomeye kubisubizo byinshyi za capacitor. Itangiza impedance ihinduka hamwe na frequence. Ubushobozi buke bwa ESR bugaragaza impedance nyinshi kuri frequency nyinshi, bikagabanya imikorere yabyo muri porogaramu zisaba intera yagutse. Ubushobozi buke bwa ESR bufite inzitizi nkeya kumurongo mugari kandi byagaragaye ko ari byiza muri ibi bihe.
Gukemura ibibazo biterwa na ESR yo hejuru,hasi-ESR MLCCsbimaze kumenyekana cyane mumyaka yashize. Izi MLCCs zakozwe hifashishijwe ibikoresho bigezweho hamwe nubuhanga bwo gukora kugirango bigere ku giciro cyo hasi cya ESR ugereranije nubushobozi busanzwe. Gutezimbere kwinshuro zabo, gukoresha ingufu nkeya no kongera imbaraga zituma biba byiza mubikorwa bitandukanye birimo ibikoresho byamashanyarazi, akayunguruzo, gushungura no kurenga.
Muncamake, ESR nikintu cyingenzi kigira ingaruka kumikorere ya capacitor. Igena imbaraga za capacitori zo gukwirakwiza, voltage ripple, umuvuduko wo guhinduranya, hamwe nigisubizo cyinshyi. Hasi ya ESR MLCCs yagaragaye nkigisubizo cyo kugabanya ibibazo bifitanye isano na ESR yo hejuru, itanga imikorere inoze kandi yizewe yibikoresho bitandukanye bya elegitoroniki hamwe nizunguruka.
