Indima yee-capacitors kubonelelo lwamandla

Ii-capacitors zingasetyenziswa ekutshintsheni izixhobo zamandla ukunciphisa ingxolo ye-ripple, ukuphucula uzinzo lombane kunye nokuphendula okwethutyana, kodwa kukho iintlobo ezininzi zazo, makhe sijonge kunye.

Uhlobo lwe-capacitor

Ii-capacitors zinokwahlulwa zibe zii-chip capacitors kunye nee-plug-in capacitors ngokwephakheji, ii-ceramic capacitors, ii-electrolytic capacitors, ii-mica capacitors, njl. ngokwe-medium, kunye nee-fixed capacitors, ii-semi-fixed capacitors, kunye nee-variable capacitors ngokwesakhiwo. Kwi-switching power supply, sisebenzisa kakhulu ii-ceramic capacitors, ii-electrolytic capacitors kunye nee-tantalum capacitors.

Iiparameter eziphambili ze-capacitor

Ukuqonda iiparameter zesitshixo sangaphakathi se-capacitor kunokukhetha ngokukhawuleza uhlobo kwaye lusetyenziswe ngokuthembekileyo. Iiparameter zesitshixo zazo zonke ii-capacitors ziyafana, kubandakanya ixabiso le-capacitance ye-capacitor, ixabiso le-standing voltage ye-capacitor, i-ESR ye-capacitor, ukuchaneka kwexabiso le-capacitor, kunye nobushushu obuvumelekileyo bokusebenza kwe-capacitor.

Iimpawu ze-capacitor ngokwayo

Ii-capacitor ze-ceramic zinomthamo omncinci, iimpawu ezilungileyo ze-high-frequency, uluhlu olubanzi lobushushu bokusebenza, i-ESR encinci kunye nomthamo omncinci kunee-capacitor ze-electrolytic;

I-capacitance ye-electrolytic capacitor inokwenziwa ibe nkulu, kodwa uluhlu lobushushu bokusebenza luncinci, i-ESR inkulu, kwaye kukho i-polarity;

Ii-capacitor zeTantalum zine-ESR encinci, kwaye amandla azo makhulu kunee-capacitor zeceramic. Zine-polarity, ukusebenza kakubi kokhuseleko, kwaye kulula ukubamba umlilo.

Qonda iimpawu zeentlobo ezintathu ze-capacitors ezingentla, kwaye ungayisebenzisa ngokulula.

Indlela eyiyo

Imeko yangaphakathi yesekethe ibandakanya i-frequency, ixabiso le-voltage, ixabiso langoku, indima ephambili ye-capacitor kwisekethe, njl.njl.; uhlobo lwe-capacitor lunokugqitywa ngokwe-frequency yesekethe; ixabiso le-voltage ye-capacitor ekhethiweyo linokugqitywa ngokwexabiso le-voltage; umsebenzi oyintloko kwisekethe ungasetyenziswa Jonga ixabiso le-capacitance ye-capacitor ekhethiweyo; imeko yangaphandle yokusetyenziswa kwesekethe, kubandakanya ubushushu obujikeleze imveliso esebenzayo, kunye neemfuno zokhuseleko, zingasetyenziswa njengesalathiso sokukhetha i-capacitor.
