Kana uchinzwisisa capacitors, imwe yeakakosha paramita yekufunga nezvayo ndeye ESR (yakaenzana akateedzana kuramba). ESR hunhu hwekuzvarwa hweese ma capacitor uye inoita basa rakakosha mukuona kuita kwavo kwese. Muchikamu chino, tichaongorora hukama pakati peESR uye capacitors, tichitarisa zvakanyanyayakaderera-ESR MLCCs(multilayer ceramic capacitors).
ESR inogona kutsanangurwa sekupikisa kunoitika mumutsara ne capacitance ye capacitor nekuda kwemaitiro asina kunaka ezvinyorwa zve capacitor. Inogona kufungidzirwa sekupikisa kunogadzirisa kuyerera kwezvino kuburikidza ne capacitor. ESR hunhu husingadiwi nekuti hunoita kuti simba riparadzwe sekupisa, nekudaro kuderedza kushanda kwecapacitor uye kukanganisa kushanda kwayo.
Saka, chii chinoita ESR pane capacitors? Ngaticherechedze zvakadzama.
1. Kuparara kwesimba: Kana ikozvino inoyerera kuburikidza ne capacitor, simba rinorasika nenzira yekupisa nekuda kwekupikisa kunopiwa neESR. Uku kupera kwesimba kunogona kukonzera kuwedzera tembiricha, izvo zvinogona kukanganisa kuita kwese uye hupenyu hwesevhisi ye capacitor. Naizvozvo, kuderedza ESR kwakakosha kudzikisa kurasikirwa kwemagetsi uye kuve nechokwadi chekushanda kwakanaka kwecapacitor.
2. Voltage Ripple: Muzvikumbiro apo capacitors anoshandiswa kusefa uye kutsvedza zvinangwa, ESR inova yakakosha parameter. ESR inogadzira mavheti emagetsi kana kushanduka kana voltage pa capacitor ichichinja nekukurumidza. Aya ma ripples anogona kukonzera kusagadzikana kwedunhu uye kukanganisa, kukanganisa kunaka kwechiratidzo chekubuda. Yakaderera ESR capacitors yakanyatso kugadzirirwa kudzikisa aya mavheti emagetsi uye kupa tambo dzemagetsi dzakagadzikana.
3. Kushandura kukurumidza: Macapacitors anowanzoshandiswa mumagetsi emagetsi anosanganisira kukurumidza kushandura mabasa. Yakakwira ESR inogona kudzikisa zvakanyanya kasidhi yekuchinja kwedunhu, zvichikonzera kunonoka uye kuderedza kushanda zvakanaka. Yakaderera ESR capacitors, kune rumwe rutivi, inopa nekukurumidza kuchaja uye kuburitsa mitengo, ichiita kuti ive yakanakira zvikumbiro zvinoda kukurumidza kuchinjika.
4. Frequency response: ESR inewo simba guru pamhinduro yakawanda ye capacitor. Inosuma impedance inoshanduka ne frequency. Yakakwira ESR capacitors inoratidza yakakwira impedance pamafafitera epamusoro, ichidzikamisa kuita kwavo mumashandisirwo anoda kuwanda frequency renji. Yakaderera ESR capacitors ine yakaderera impedance pamusoro peyakafara frequency spectrum uye inoratidzirwa kuve inoshanda zvakanyanya mumamiriro ezvinhu aya.
Kugadzirisa matambudziko anokonzerwa neESR yakakwirira,yakaderera-ESR MLCCsdzave dzakakurumbira mumakore achangopfuura. Aya maMLCC anogadzirwa achishandisa zvigadzirwa zvepamberi uye nzira dzekugadzira kuti awane yakaderera zvakanyanya ESR kukosha kana ichienzaniswa neyakajairwa capacitor. Mhinduro yavo yekuvandudzwa kwema frequency, mashandisiro emagetsi mashoma uye kugadzikana kwakawedzera kunoita kuti ive yakakodzera kune akasiyana maapplication anosanganisira magetsi emagetsi, mafirita maseketi, decoupling uye bypass.
Muchidimbu, ESR ndiyo parameter yakakosha inobata capacitor performance. Iyo inosarudza iyo capacitor's simba dissipation, voltage ripple, switching kasi, uye frequency mhinduro. Yakaderera ESR MLCCs yakabuda semhinduro yekudzikisa matambudziko ane chekuita neESR yakakwirira, inopa kushanda kwakanaka uye kwakavimbika kwemhando dzakasiyana dzemagetsi uye maseketi.
