Uma kukhulunywa nge-MLCC (i-Multilayer Ceramic Capacitor), isici esisodwa esibalulekile okufanele sicabange ukumelana nokumelana okufanayo kochungechunge (ESR). I-ESR ye-capacitor ibhekisela ekumelaneni kwangaphakathi kwe-capacitor. Ngamanye amagama, kulinganisa ukuthi i-capacitor iphatha kanjani ukushintshana kwamanje (AC). Ukuqonda i-ESR yeAma-capacitors we-MLCCKubalulekile kwizicelo eziningi ze-elekthronikhi, ikakhulukazi labo abadinga ukusebenza okuzinzile kanye nokusetshenziswa kwamandla okuphansi.
I-ESR ye-MLCC Capacitor ithintekile yizici eziningi, njengokuzakwa kwezinto ezibonakalayo, isakhiwo, nosayizi.Ama-capacitors we-MLCCzivame ukwakhiwa kusuka ezingxenyeni eziningi ze-ceramic impahla ehlanganisiwe, ngesendlalelo ngasinye esihlukaniswe ngama-electrodes zensimbi. Izinto ze-ceramic zokuzikhethela kwalawa ma-capacitors zivame ukuhlanganiswa kwe-titanium, zirconium, nezinye izinkabi zensimbi. Lezi zinto ezisetshenziswayo zikhethwe ngokucophelela ukuhlinzeka ngamanani aphezulu okukhohlisa kanye nokuvinjwa okuphansi ngamaza aphezulu.
Ukunciphisa i-ESR, abakhiqizi bavame ukusebenzisa ubuchwepheshe obuhlukile kwinqubo yokukhiqiza. Enye inqubo enjalo ukufaka izinto ezisebenzayo, njengesiliva noma ithusi, ngesimo sokunameka okusebenzayo. Lezi zinhlaka eziqhutshwa zisetshenziselwa ukudala ama-electrodes axhumeka izingqimba ze-ceramic, ngaleyo ndlela anciphise i-ESR ephelele. Ngaphezu kwalokho, abakhiqizi bangafaka ungqimba oluncane lwezinto ezisebenzayo ebusweni beI-MLCC Capacitorukunciphisa u-ESR.
I-ESR ye-MLCC Capacitor ilinganiswa kuma-ohms futhi ingahluka ngokuya ngesicelo. Amanani aphansi e-ESR ngokuvamile afiseleka ngoba akhombisa ukuthuthuka okungcono nokulahleka kwamandla aphansi. Ama-capacitors aphansi e-ESR alungele kangcono izinhlelo zokusebenza ezidinga ukusebenza imvamisa ephezulu, njengokuhlinzekwa kwamandla kanye nemibuthano yokukhohlisa. Banikeza ukuqina okungcono nokusebenza kahle futhi bangaphatha izinguquko ezisheshayo kumandla kagesi ngaphandle kokulahlekelwa okubalulekile.
Kodwa-ke, kufanele kuphawulwe ukuthiAma-capacitors we-MLCCnge-ESR ephansi kakhulu kungenzeka futhi ibe nemikhawulo. Kwezinye izinhlelo zokusebenza, i-ESR ephansi kakhulu ingadala ukuphikiswa okungafuneki nokusebenza okungazinzi. Ngakho-ke, kubalulekile ukuthi ukhethe ngokucophelela i-MLCC Capacitor ngenani le-ESR elilungele izidingo ezithile zesifunda.
Ngaphezu kwalokho, i-ESR yeAma-capacitors we-MLCCIzinguquko ngokuhamba kwesikhathi ngenxa yezinto ezifana nokuguga nokushisa kwezilinganiso. Ukuguga kweCapacitor kubangela ukuthi i-ESR iphume, ithinta ukusebenza kwezesekethwa. Lezi zinto kufanele zibhekwe lapho ziklama amasistimu kagesi ukuqinisekisa ukuthembeka kwesikhathi eside nokuqina.
Ngamafuphi, i-ESR ye-MLCC Capacitor idlala indima ebalulekile ekunqumeni izici zayo zikagesi. Le yipharamitha ebalulekile okufanele uyicabangele lapho ukhetha ama-capacitors ngezinhlelo zokusebenza ezahlukahlukene ze-elekthronikhi. Ama-capacitors we-MLCC ane-ESR ephansi athuthukisa ukusebenza kahle nokuqina futhi alungele amasekethe avama kakhulu. Kodwa-ke, inani le-ESR kumele lilinganise ngokumelene nezidingo ezithile zesifunda ukuqinisekisa ukusebenza kahle nokwethembeka.
