Kana zvasvika kune MLCC (Multilayer Ceramic Capacitor) capacitors, chimwe chinhu chakakosha chekutarisa ndeye Equivalent Series Resistance (ESR).ESR ye capacitor inoreva kupikisa kwemukati kwe capacitor.Mune mamwe mazwi, inoyera kuti nyore sei capacitor inoitisa alternating ikozvino (AC).Kunzwisisa ESR yeMLCC capacitorsyakakosha mumashandisirwo mazhinji emagetsi, kunyanya ayo anoda kushanda kwakagadzikana uye kuderera kwesimba rekushandisa.
Iyo ESR yeMLCC capacitor inobatwa nezvinhu zvakawanda, senge kuumbwa kwezvinhu, chimiro, uye saizi.MLCC capacitorsanowanzo kuvakwa kubva kune akawanda akaturikidzana eceramic zvinhu akaturikidzana, nechero imwe neimwe yakapatsanurwa nesimbi electrode.Iyo ceramic material yesarudzo yeaya macapacitor inowanzove musanganiswa wetitanium, zirconium, uye mamwe simbi oxides.Izvi zvinhu zvinonyatsosarudzwa kuti zvipe yakakwira capacitance kukosha uye yakaderera impedance pane yakakwirira frequency.
Kudzikisa ESR, vagadziri vanowanzo shandisa akasiyana matekinoroji mukugadzira maitiro.Imwe nzira yakadaro ndeyekusanganisira chinhu chinoitisa, senge sirivheri kana mhangura, muchimiro che conductive paste.Aya mafiritsi anofambisa anoshandiswa kugadzira maelectrodes anobatanidza zvidimbu zveceramic, nekudaro kuderedza ESR yese.Mukuwedzera, vagadziri vanogona kushandisa chidimbu chakaonda che conductive zvinhu pamusoro peMLCC capacitorkuwedzera kuderedza ESR.
Iyo ESR yeMLCC capacitor inoyerwa muohms uye inogona kusiyana zvichienderana nekushandiswa.Lower ESR tsika dzinowanzodiwa nekuti dzinoratidza zviri nani conductivity uye kuderera kwesimba kurasikirwa.Yakaderera ESR capacitors inokodzera zvirinani kune maapplication anoda yakakwira frequency kuita, senge magetsi emagetsi uye decoupling maseketi.Ivo vanopa kugadzikana kuri nani uye kugona uye vanogona kubata nekukurumidza shanduko mumagetsi pasina kurasikirwa kukuru.
Zvisinei, zvinofanira kucherechedzwa kutiMLCC capacitorsine ESR yakanyanya kuderera inogonawo kuva nemiganhu.Mune mamwe maapplication, iyo ESR yakaderera zvakanyanya inogona kukonzera kusingadiwi resonance uye kusagadzikana kushanda.Naizvozvo, zvakakosha kunyatsosarudza MLCC capacitor ine kukosha kweESR inokodzera izvo zvinodiwa zvedunhu.
Mukuwedzera, iyo ESR yeMLCC capacitorskuchinja nekufamba kwenguva nekuda kwezvinhu zvakadai sekukwegura uye kuchinja kwekushisa.Kuchembera kwe capacitor kunoita kuti ESR iwedzere, inokanganisa kushanda kwese kwedunhu.Izvi zvinhu zvinofanirwa kutariswa pakugadzira masisitimu emagetsi kuti ave nechokwadi chekuvimbika uye kugadzikana kwenguva refu.
Muchidimbu, iyo ESR yeMLCC capacitor inoita basa rakakosha pakusarudza maitiro ayo emagetsi.Iyi ndiyo parameter yakakosha yekufunga nezvayo pakusarudza ma capacitor eakasiyana emagetsi maapplication.MLCC capacitors ine yakaderera ESR inovandudza kugona uye kugadzikana uye yakanakira yakakwira frequency maseketi.Nekudaro, kukosha kweESR kunofanirwa kuenzana nezvinodiwa zvedunhu kuti ive nechokwadi chekuita kwakanaka uye kuvimbika.
