Electrolytic vs Ceramic Capacitor
Ib lub capacitor yog cov khoom siv hluav taws xob uas tuaj yeem khaws cov nqi hluav taws xob. Capacitors tseem hu ua condenser. Ceramic capacitors thiab electrolytic capacitor yog ob lub ntsiab ntawm cov capacitors uas tau siv dav hauv cov khoom siv hluav taws xob thiab hluav taws xob. Ceramic capacitor siv ib txheej nyias nyias raws li qhov nruab nrab dielectric thaum lub electrolytic capacitor siv cov kua ionic ua ib daim ntawv ntawm lub capacitor. Hauv tsab xov xwm no, peb yuav tham txog dab tsi electrolytic capacitor thiab ceramic capacitor yog, lawv cov khoom, thiab thaum kawg ib qho kev sib piv ntawm electrolytic capacitor thiab ceramic capacitor thiab xaus qhov txawv ntawm ceramic capacitors thiab electrolytic capacitor.
Ceramic Capacitor yog dab tsi?
Yuav kom nkag siab tias lub capacitor ceramic yog dab tsi ib qho yuav tsum xub nkag siab tias lub capacitor yog dab tsi. Capacitor yog cov cuab yeej siv los khaws cov nqi. Capacitors tseem hu ua condenser. Commercially siv capacitors yog ua los ntawm ob hlau foils nrog ib tug dielectric nruab nrab ntawm lawv dov mus rau hauv lub tog raj kheej. Lub capacitance yog cov cuab yeej tseem ceeb ntawm lub capacitor.
Lub peev xwm ntawm ib qho khoom yog qhov ntsuas ntawm tus nqi ntawm cov khoom uas tuaj yeem tuav tsis tau tawm. Capacitance yog ib qho khoom tseem ceeb hauv ob qho tib si hauv hluav taws xob thiab electromagnetism. Capacitance kuj txhais tau tias yog lub peev xwm khaws lub zog hauv qhov hluav taws xob. Rau lub capacitor, uas muaj qhov sib txawv V voltage hla cov nodes thiab qhov siab tshaj plaws ntawm cov nqi uas tuaj yeem khaws cia hauv qhov system yog Q, lub peev xwm ntawm lub kaw lus yog Q / V, thaum tag nrho cov ntsuas hauv SI units. Chav tsev ntawm lub capacitance yog farad (F). Txawm li cas los xij, vim nws tsis yooj yim rau siv xws li chav tsev loj, feem ntau ntawm qhov muaj peev xwm raug ntsuas hauv nF, pF, µF thiab mF ntau yam.
Nyob rau hauv ceramic capacitor, txheej nyias nyias ua raws li qhov nruab nrab dielectric. Ceramic capacitor tsis muaj polarity. Ceramic capacitor raug faib ua peb chav kawm loj. Chav kawm I capacitors muaj qhov tseeb zoo dua thiab qhov ua tau zoo ntawm cov khoom siv hluav taws xob tsawg thaum chav kawm III capacitors muaj qhov tseeb qis thiab ua haujlwm siab volumetric.
Electrolytic Capacitor yog dab tsi?
Ib lub tshuab hluav taws xob electrolytic yog tsim los ntawm kev muaj cov kua ionic ua ib qho ntawm cov khoom siv ntawm lub capacitor. Feem ntau ntawm cov electrolyte capacitor yog polarized. Qhov no txhais tau hais tias qhov hluav taws xob ntawm lub anode tsis tuaj yeem dhau los ua qhov tsis zoo rau qhov voltage thov rau cathode. Yog hais tias qhov no tshwm sim, lub capacitor yuav corrupted los ntawm ion pauv. Electrolytic capacitors yog nto moo rau muaj ntau dua volumetric efficiency. Qhov no txhais tau hais tias ib tug me me capacitor muaj peev xwm tuav tus nqi loj dua li lub ceramic capacitor ntawm tib qhov loj.
Qhov txawv ntawm Ceramic Capacitor thiab Electrolytic Capacitor yog dab tsi?
• Ceramic capacitor muaj ob daim ntawv hlau ntawm lub davhlau ya nyob twg los khaws cov nqi. Lub electrolytic capacitor muaj ib daim hlau thiab cov kua ionic li ob lub terminals.
• Electrolytic capacitors muaj peev xwm tuav tau nqi ntau dua ib lub ntim dua li cov ceramics.
• Feem ntau ntawm cov electrolyte capacitors yog polarized, tab sis ceramic capacitors yeej tsis polarized.
