Chii chinonzi ESR ye MLCC capacitor?

Kana zvasvika kuma capacitor eMLCC (Multilayer Ceramic Capacitor), chimwe chinhu chakakosha chekufunga nezvacho iEquivalent Series Resistance (ESR). ESR ye capacitor inoreva resistance yemukati ye capacitor. Nemamwe mashoko, inoyera kuti capacitor inotungamira sei alternating current (AC) zviri nyore. Kunzwisisa ESR yeMa capacitor eMLCCinokosha mumabasa mazhinji emagetsi, kunyanya ayo anoda kushanda kwakasimba uye kushandiswa kwesimba shoma.

ESR ye MLCC capacitor inokanganiswa nezvinhu zvakawanda, zvakaita sekuumbwa kwezvinhu, chimiro, uye saizi.Ma capacitor eMLCCZvinowanzo gadzirwa nematanda akawanda eceramic akaunganidzwa, rimwe nerimwe rakapatsanurwa nema electrodes esimbi. Chinhu checeramic chinosarudzwa nema capacitors aya chinowanzova musanganiswa we titanium, zirconium, nedzimwe metal oxides. Zvinhu izvi zvinosarudzwa nokungwarira kuti zvipe simba rakawanda uye impedance yakaderera pama frequency akakwira.

Kuti vagadziri vaderedze ESR, vanowanzo shandisa matekinoroji akasiyana mukugadzira. Imwe nzira yakadaro ndeyekushandisa zvinhu zvinofambisa mhepo, zvakaita sesirivha kana mhangura, muchimiro che conductive paste. Izvi zvinoshandiswa kugadzira ma electrodes anobatanidza ceramic layers, nokudaro zvichideredza ESR yese. Pamusoro pezvo, vagadziri vanogona kuisa chidimbu chakatetepa che conductive material pamusoro peMLCC capacitorkuderedza ESR zvakanyanya.

ESR ye MLCC capacitor inoyerwa mu ohms uye inogona kusiyana zvichienderana nekushandiswa kwayo. Ma ESR akaderera anowanzo dikanwa nekuti anoratidza conductivity iri nani uye kurasikirwa nesimba kwakaderera. Ma ESR capacitors akaderera akakodzera zvirinani maapplication anoda kushanda kwema frequency akawanda, akadai semagetsi uye circuits dzinobatanidza. Anopa kugadzikana kuri nani uye kushanda zvakanaka uye anogona kugadzirisa shanduko dzinokurumidza mu voltage pasina kurasikirwa kukuru.

Zvisinei, zvinofanira kucherechedzwa kutiMa capacitor eMLCCneESR yakaderera zvakanyanya inogonawo kuva nemiganhu. Mune mamwe mashandisirwo, ESR yakaderera zvakanyanya inogona kukonzera kurira kusingadiwe uye kushanda kusina kugadzikana. Saka, zvakakosha kusarudza zvakanaka capacitor yeMLCC ine kukosha kweESR yakakodzera zvinodiwa zvedunhu.

Uye zvakare, ESR yeMa capacitor eMLCCKuchinja-chinja nekufamba kwenguva nekuda kwezvinhu zvakaita sekukwegura uye kuchinja kwetembiricha. Kukwegura kwecapacitor kunoita kuti ESR iwedzere, zvichikanganisa mashandiro ese ecircuit. Zvinhu izvi zvinofanirwa kufungwa nezvazvo pakugadzira masisitimu emagetsi kuti ive nechokwadi chekuti akavimbika uye akasimba kwenguva refu.

Muchidimbu, ESR ye MLCC capacitor ine basa rakakosha pakuona hunhu hwayo hwemagetsi. Iyi iparameter yakakosha yekufunga nezvayo pakusarudza ma capacitor ekushandisa zvakasiyana-siyana zvemagetsi. Ma MLCC capacitors ane ESR yakaderera anovandudza kushanda zvakanaka uye kugadzikana uye akakodzera ma frequency circuits akawanda. Zvisinei, kukosha kweESR kunofanirwa kuenzaniswa nezvinodiwa zve circuit kuti ive nechokwadi chekuti inoshanda zvakanaka uye yakavimbika.
