Niki ESR ya capacitori ya MLCC?

Iyo bigeze kuri capacator ya MLCC (Multilayer Ceramic Capacitor), ikintu kimwe cyingenzi kiranga gutekereza ni Ikigereranyo cya Resistance (ESR). ESR ya capacitor bivuga kurwanya imbere kwimbere. Muyandi magambo, ipima uburyo byoroshye capacitor ikora ibintu bisimburana (AC). Gusobanukirwa ESR yaUbushobozi bwa MLCCni ingenzi mubikorwa byinshi bya elegitoronike, cyane cyane bisaba imikorere ihamye no gukoresha ingufu nke.

ESR ya capacitor ya MLCC yibasiwe nibintu byinshi, nkibigize ibintu, imiterere, nubunini.Ubushobozi bwa MLCCmubisanzwe byubatswe mubice byinshi byibikoresho bya ceramic byegeranye, hamwe na buri cyiciro gitandukanijwe nicyuma cya electrode. Ibikoresho bya ceramic byo guhitamo kuri capacator mubisanzwe ni uruvange rwa titanium, zirconium, nibindi byuma bya okiside. Ibi bikoresho byatoranijwe neza kugirango bitange ubushobozi buhanitse hamwe na impedance nkeya kuri frequency nyinshi.

Kugabanya ESR, abayikora akenshi bakoresha tekinoroji zitandukanye mubikorwa byo gukora. Bumwe muri ubwo buryo ni ugushyiramo ibikoresho bitwara, nka feza cyangwa umuringa, muburyo bwa paste. Izi paste ziyobora zikoreshwa mugukora electrode ihuza ibice bya ceramic, bityo bikagabanya ESR muri rusange. Mubyongeyeho, abayikora barashobora gukoresha urwego ruto rwibikoresho byayobora hejuru yUbushobozi bwa MLCCkurushaho kugabanya ESR.

ESR ya capacitori ya MLCC ipimwa muri ohms kandi irashobora gutandukana bitewe na porogaramu. Indangagaciro za ESR zo hasi muri rusange zirifuzwa kuko zerekana neza neza no gutakaza ingufu nke. Ubushobozi buke bwa ESR bukwiranye na porogaramu zisaba imikorere yumurongo mwinshi, nkibikoresho byamashanyarazi hamwe nizunguruka. Zitanga umutekano ushimishije kandi zirashobora gukemura impinduka zihuse muri voltage nta gihombo gikomeye.

Ariko, tugomba kumenya koUbushobozi bwa MLCChamwe na ESR yo hasi cyane irashobora kandi kugira aho igarukira. Mubisabwa bimwe, ESR iri hasi cyane irashobora gutera resonance idakenewe nigikorwa kidahungabana. Kubwibyo, ni ngombwa guhitamo witonze ubushobozi bwa MLCC ifite ubushobozi bwa ESR bukwiranye nibisabwa byumuzunguruko.

Byongeye, ESR yaUbushobozi bwa MLCCimpinduka mugihe bitewe nibintu nko gusaza no guhinduka kwubushyuhe. Gusaza kwa capacitori bituma ESR yiyongera, bigira ingaruka kumikorere rusange yumuzunguruko. Izi ngingo zigomba gusuzumwa mugihe hateguwe sisitemu ya elegitoronike kugirango harebwe igihe kirekire kandi cyizewe.

Muri make, ESR ya capacitori ya MLCC igira uruhare runini mukumenya ibiranga amashanyarazi. Nibintu byingenzi ugomba gusuzuma muguhitamo ubushobozi bwa porogaramu zitandukanye za elegitoroniki. Ubushobozi bwa MLCC hamwe na ESR yo hasi butezimbere imikorere kandi itajegajega kandi nibyiza kumuzunguruko mwinshi. Nyamara, agaciro ka ESR kagomba kuringanizwa nibisabwa byumuzunguruko kugirango hamenyekane imikorere myiza kandi yizewe.
