Txoj cai thiab kev siv ntawm electrolytic capacitor

txoj cai

Electrolytic capacitors feem ntau yog ua los ntawm cov ntawv hlau (aluminium / bismuth) ua ib qho zoo electrode, insulating oxide txheej ntawm aluminium foil (aluminium oxide / yttrium oxide) raws li dielectric, thiab electrolytic capacitors muab faib ua txhuas electrolytic capacitors thiab tantalum electrolysis los ntawm lawv. zoo electrodes. Capacitor. Qhov tsis zoo electrode ntawm aluminium electrolytic capacitor yog tsim los ntawm ib daim ntawv nyias / zaj duab xis lossis ib qho electrolyte polymer rau hauv cov kua electrolyte (kua electrolyte); Qhov tsis zoo electrode ntawm tantalum electrolytic capacitor feem ntau yog manganese dioxide. Txij li thaum cov electrolyte yog siv los ua qhov tsis zoo electrode (nco ntsoov tias nws txawv ntawm dielectric), lub electrolytic capacitor muaj npe tom qab nws.

daim ntawv thov

Polar electrolytic capacitors feem ntau ua haujlwm raws li cov khoom siv hluav taws xob lim dej, decoupling, teeb liab sib txuas, lub sijhawm teeb tsa, thiab DC thaiv hauv cov khoom siv hluav taws xob lossis cov zaus nruab nrab thiab qis zaus. Feem ntau, nws tsis tuaj yeem siv rau hauv AC fais fab mov Circuit Court. Thaum siv los ua lub tshuab lim dej hauv DC lub zog hluav taws xob, lub anode (zoo electrode) yuav tsum tau txuas nrog lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob, thiab cathode (tsis zoo electrode) yuav tsum txuas nrog qhov tsis zoo ntawm lub zog hluav taws xob. hluav taws xob. Txwv tsis pub nws yuav ua rau lub apacitor puas.

Tsis yog-polar electrolytic capacitor feem ntau yog siv hauv cov lus sib faib circuits, TV S kho circuits, thiab pib-up circuits rau ib-theem motors.

Electrolytic capacitor yog dav siv hauv cov khoom siv hauv tsev thiab ntau yam khoom siv hluav taws xob. Lawv muaj peev xwm ntawm 1 mus rau 33000 μF thiab ntsuas kev ua haujlwm voltages ntawm 6.3 txog 700V. Qhov tsis zoo yog qhov tsis zoo ntawm dielectric thiab lub peev xwm yuam kev yog qhov loj (qhov siab tshaj plaws tso cai sib txawv yog +100%, -20}%), qhov kub tsis zoo yog qhov tsis zoo, thiab lub sijhawm cia ntev thiab yooj yim rau kev khiav lag luam. ua tsis raug.

Lub polarity ntawm lub electrolytic capacitor, xyuam xim rau "-" nyob rau sab ntawm lub electrolytic capacitor yog qhov tsis zoo, "+" yog qhov zoo, yog tias lub electrolytic capacitor tsis cim qhov zoo thiab tsis zoo, nws kuj tuaj yeem txiav txim raws li mus rau qhov ntev ntawm nws tus pin, ntev taw Rau tus ncej zoo, ceg luv yog tus ncej tsis zoo
