Xa kuziwa kwi-MLCC (i-Multilayer Ceramic Capacitor) i-capacitors, enye impawu ebalulekileyo yokuqwalasela i-Equivalent Series Resistance (ESR).I-ESR ye-capacitor ibhekisela ekuchaseni kwangaphakathi kwe-capacitor.Ngamanye amazwi, ilinganisa ukuba kulula kangakanani i-capacitor ukuqhuba i-alternating current (AC).Ukuqonda iESR yeI-MLCC capacitorsibaluleke kakhulu kwizicelo ezininzi ze-elektroniki, ngakumbi ezo zifuna ukusebenza okuzinzileyo kunye nokusetyenziswa kwamandla aphantsi.
I-ESR ye-MLCC capacitor ichaphazeleka kwizinto ezininzi, ezifana nokubunjwa kwezinto, ukwakheka kunye nobukhulu.I-MLCC capacitorsziqhele ukwakhiwa ukusuka kwiileya ezininzi zemathiriyeli ye-ceramic epakishwe, kunye nomaleko ngamnye owahlulwe ngee-electrode zetsimbi.Izinto ze-ceramic ezikhethiweyo zezi capacitors zihlala zidibanisa i-titanium, i-zirconium, kunye nezinye i-oxides zetsimbi.Ezi zixhobo zikhethwe ngononophelo ukuze zibonelele ngamaxabiso aphezulu obuchule kunye ne-impedance ephantsi kumaza aphezulu.
Ukunciphisa i-ESR, abavelisi bahlala besebenzisa itekhnoloji eyahlukeneyo kwinkqubo yokuvelisa.Olunye ubugcisa obunjalo kukubandakanya izinto eziphathekayo, ezifana nesilivere okanye ubhedu, ngendlela ye-condutive paste.Ezi pastes conductive zisetyenziselwa ukwenza i-electrodes edibanisa iileya ze-ceramic, ngaloo ndlela inciphisa i-ESR iyonke.Ukongeza, abavelisi banokusebenzisa umaleko omncinci wezinto eziqhubayo kumphezulu weI-MLCC capacitorukunciphisa ngakumbi i-ESR.
I-ESR ye-MLCC capacitor ilinganiswa kwii-ohms kwaye ingahluka ngokuxhomekeka kwisicelo.Amaxabiso aphantsi e-ESR anqweneleka ngokubanzi kuba abonisa ukuhanjiswa okungcono kunye nokulahleka kwamandla aphantsi.I-ESR capacitors ephantsi ifaneleka ngakumbi kwizicelo ezifuna ukusebenza kwamafrikhwensi aphezulu, njengamandla ombane kunye neesekethe zokuqhawula.Banikezela ngozinzo olungcono kunye nokusebenza kakuhle kwaye banokusingatha utshintsho olukhawulezayo kumbane ngaphandle kwelahleko enkulu.
Nangona kunjalo, kufuneka kuqatshelwe ukubaI-MLCC capacitorseneESR ephantsi kakhulu inokuba nemida.Kwezinye izicelo, iESR ephantsi kakhulu inokubangela i-resonance engafunekiyo kunye nokusebenza okungazinzanga.Ke ngoko, kubalulekile ukukhetha ngononophelo i-MLCC capacitor enexabiso le-ESR elilungele iimfuno ezithile zesekethe.
Ukongeza, i-ESR yeI-MLCC capacitorsutshintsho ekuhambeni kwexesha ngenxa yezinto ezifana nokuguga nokutshintsha kobushushu.Ukuguga kwe-capacitor kubangela ukuba i-ESR inyuke, ichaphazele ukusebenza ngokubanzi kwesekethe.Ezi zinto kufuneka ziqwalaselwe xa kuyilwa iinkqubo zombane ukuqinisekisa ukuthembeka kunye nokuzinza kwexesha elide.
Isishwankathelo, i-ESR ye-MLCC capacitor idlala indima ebalulekileyo ekunqumeni iimpawu zayo zombane.Le yiparameter ebalulekileyo ekufuneka iqwalaselwe xa ukhetha i-capacitors kwizicelo ezahlukeneyo ze-elektroniki.I-MLCC capacitors ene-ESR ephantsi iphucula ukusebenza kakuhle kunye nokuzinza kwaye ifanelekile kwiisekethe eziphezulu.Nangona kunjalo, ixabiso le-ESR kufuneka lilinganiswe kwiimfuno ezithile zesekethe ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthembeka.
