A CA501 axial ntub tantalum capacitor tsim los ntawm BEC yog ib hom siab - kub, ntub electrolytic tantalum capacitor nrog axial coj los ntawm ob sab sib txawv. Nws tau paub txog kev ua tau zoo, kev ntseeg siab thiab kev pabcuam ntev thiab txee lub neej nyob rau hauv huab cua txias, tshwj xeeb tshaj yog mus txog 175 degree. Cov yam ntxwv no ua rau nws zoo tagnrho rau cov roj drilling, aerospace thiab lwm yam hnyav -ib puag ncig daim ntaub ntawv xav tau kev ruaj khov fais fab lim los yog mem tes circuits. Nws nta cov ntaub ntawv nyiaj, iav foob, thiab polarity, muab siab capacitance hauv ib pob me me. Nws ua tau raws li tus qauv QJ/PWV223 - 2008. nws yog dav siv hauv cov roj thiab roj tshawb nrhiav thiab cov khoom siv drilling, nrog rau lwm cov khoom siv hluav taws xob kub lossis hluav taws xob tiv taus hauv DC lossis mem tes circuits.

Yam ntxwv
Electrolyte ntub dej (Foil):Tsis zoo li cov khoom tantalum capacitor, CA501 capacitor siv cov kua sulfuric acid electrolyte. Qhov no muab nws qhov zoo sib xws thiab tuav cov cai.
Cathode System:Cov kua electrolyte ua raws li cov cathode, tso cai rau nws tus kheej - kho cov me me dielectric flaws, uas yog ib qho tseem ceeb kev ntseeg siab feature.
High Capacitance Stability:Zoo heev capacitance tuav nyob rau hauv ntau qhov kub thiab txias ntau zaus piv rau cov khoom tantalum capacitors.
Tsawg sib npaug Series Resistance (ESR):ESR tsawg heev nyob rau hauv ib tug dav zaus spectrum, ua rau lawv haum rau lim thiab bypassing nyob rau hauv siab - zaus thiab mem tes fais fab circuits.
Tsawg Leakage Tam sim no:DC tsis tshua muaj hluav taws xob tam sim no uas yog qhov tseem ceeb rau lub sij hawm circuits, piv txwv - thiab - tuav daim ntawv thov, thiab ntev - lub sij hawm teeb liab kev ncaj ncees.
Zoo heev zaus teb:Khaws capacitance zoo dua ntawm cov zaus siab.
Reverse Voltage kam rau ua:Feem ntau tuaj yeem tiv taus 3% mus rau 5% ntawm qhov ntsuas hluav taws xob DC rov qab.

FAQ
Q1: Dab tsi yog qhov dej ntws tawm tam sim no?
A1: Cov dej ntws tawm tam sim no tsawg heev, feem ntau suav los ntawm cov qauv: Kuv Tsawg dua lossis sib npaug rau 0.0005 * C * V (µA) lossis 2µA ntawm 25℃thiab 30µA ntawm 175 degree, qhov twg ntau dua. Rau 100µF, 50V cap, qhov ntawd tsawg dua lossis sib npaug li 2.5µA. Cov nqi tiag tiag hauv qhov zoo feem ntau qis dua.
Q2: Yuav ua li cas rov qab voltage CA501 capacitor tiv taus?
A2: Qhov no yog qhov txiaj ntsig tseem ceeb. Feem ntau CA501 capacitors tso cai rau qhov rov qab tsis tu ncua ntawm 3% mus rau 5% ntawm qhov ntsuas DC ua haujlwm voltage ntawm +25℃(xws li, 50V rated ib feem tuaj yeem tiv taus ~ 1.5V rau 2.5V rov qab). Qhov nyiaj pub no txo qis ntawm qhov kub siab dua.
Q3: Kuv puas tuaj yeem yoj solder lossis reflow solder CA501 capacitor?
A3: Wave soldering yog tus qauv thiab siv tau los muab kev txwv thermal. Lawv raug soj ntsuam. Cov txheej txheem infrared lossis vapor theem reflow soldering feem ntau tsis pom zoo vim tias muaj kev pheej hmoo ntawm kev tsim siab sab hauv los ntawm cua sov cov kua electrolyte kaw.
Q4: Vim li cas CA501 capacitors 'ESR qis, thiab vim li cas nws tseem ceeb?
A4: Qhov qis ESR yog qhov tshwm sim ncaj qha ntawm qhov siab - conductivity kua electrolyte. Nws tseem ceeb Vim tias nws txo qis hluav taws xob poob thiab cua sov hauv siab - ripple lossis pulsed daim ntawv thov. Nws muab qhov siab tshaj - zaus decoupling thiab lim kev ua haujlwm. Nws tso cai rau siab dua surge thiab ripple tam sim no tuav.
