Kana kunzwisisa capacitors, imwe yeakakosha parameter kufunga ndeye ESR (yakaenzana nheyo dzesimba). Esr ihwo humbowo hwezvese maungira ese uye anoita basa rakakosha mukusarudza kuita kwavo kwese. Munyaya ino, isu tichaongorora hukama pakati peESR uye capacitors, kutarisa zvakananga paneLow-Esr MLCCts(Multillyer ceramic capacitors).
Esr inogona kutsanangurwa seyakapokana iyo inoitika mune dzakateedzana nehuwandu hwekugona kwe capacitritor nekuda kwekusanzwisisika maitiro ezvinyorwa zvecapa. Inogona kufungwa seyekudzivisa iyo inogumira kuyerera kweazvino kuburikidza necapacitor. Esr hunhu husina kukodzera nekuti hunokonzeresa kusimudzwa sekupisa, nekudaro kuderedza kugona kweiyo capacitor uye kukanganisa maitiro ayo.
Saka, itsr ane maitiro anoitei pamataciti? Ngatitarisei mune izvo.
1. Kupararira kwemagetsi: Kana razvino kuyerera kuburikidza necapacitor, simba rakarasika muchimiro chekupisa nekuda kwekupokana kwakapihwa neESR. Uku kusarongeka kwemagetsi kunogona kukonzera tembiricha inowedzera, iyo inogona kukanganisa zvakanyanya kuita kwekuita kwakazara uye kwebasa rehupenyu hwe capacitor. Naizvozvo, kuderedza ESR kwakakosha kuti uderedze kurasikirwa kwesimba uye kuve nechokwadi chekushanda kwakanaka kweiyo capacitor.
2. Esr inoburitsa voltage ripples kana kuchinjika kana voltage mhiri kwemuchadenga vachipfuura vachipfuura nekukurumidza. Iyi ripples inogona kukonzeresa kusagadzikana kwedunhu uye kukanganisa, inokanganisa kunaka kweiyo chiratidzo chekubuda. Low Esr capacitors yakagadzirirwa kunyatso kuderedza idzi ripples uye kupa mitsara yakagadzikana.
3. Kuchinjisa kumhanya: Capacitors inowanzoshandiswa mumatunhu emagetsi kunosanganisira kukurumidza kuchinja mashandiro. Yakakwira Esr inogona kudzikisira zvakanyanya kudzikira kwekutanga kwekumhanya, zvichikonzera kunonoka uye kuderedza kushanda kwekushanda. Lowr Esr Capacitors, kune rumwe rutivi, ipa nekukurumidza kubhadharisa mhosva uye kuraswa mitengo, ichiita kuti vave vakanakira zvikumbiro izvo zvinoda nekukurumidza kuchinja.
4 Iyo inosvitsa kusakwana inoshanduka neye frequency. Yakakwira Esr capacitors inoratidza yakakwira kusakwana pamadziro epamusoro, kudzikisira kuita kwavo mune ma application inoda yakafara frequency. Low Esr capacitors ine yakaderera kusakwana pamusoro pehuremu hwekutarisa huwandu uye zvinangwa kuti ubudirire mumamiriro ezvinhu aya.
Kugadzirisa matambudziko akabvunzwa neakakwirira ESR,Low-Esr MLCCtsvava kuzivikanwa mumakore achangopfuura. Aya mlccs anogadzirwa uchishandisa zvigadzirwa zvepamberi uye maitiro ekugadzira kuti uwane zvakanyanya kuderera kwakadzika ESR tsika zvichienzaniswa nemagungano akajairwa. Mhinduro yavo yekuvandudzwa, yekudzikira masimba masimba uye kusunganidzwa kunoita kuti ive yakakodzera kune dzakasiyana-siyana dzekushandisa zvinosanganisira simba zvinhu, matunhu efaira, demagling uye bypass.
Mune pfupiso, Esr ikiyi paramende inokanganisa capacitor kuita. Iyo inosarudza iyo capacitor yemagetsi yekusagadzikana, voltage ripple, kuchinjisa kumhanya, uye mhinduro yekufambisa. Low Esr mlccs yakabuda semhinduro yekuderedza matambudziko anoenderana neyekumusoro ESR, kupa inoshanda uye yakavimbika kushanda kwemidziyo yemhando dzakasiyana siyana nematunhu.
