Lub CA axial khoom tantalum capacitor tsim los ntawm BEC yog ib qho kev txhim khu kev qha thiab polarized hluav taws xob uas siv tantalum anode, tantalum pentoxide dielectric, thiab cov khoom manganese dioxide (MnO2) cathode. Nws yog nyob rau hauv ib tug tubular, hermetically kaw nrog ob tug coj los ntawm ob qho kawg (cylindrical hom). Nws yog qhov tshwj xeeb rau kev ruaj khov thiab kev ua haujlwm zoo hauv cov ntawv thov xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua tub rog thiab ua lub luag haujlwm hauv kev muab lub peev xwm loj hauv qhov me me uas tsis tshua muaj paug thiab muaj kev ruaj ntseg zoo. Cov kab hluav taws xob no tau siv dav hauv aerospace thiab chaw tiv thaiv hauv cov khoom siv fais fab rau satellites, missiles, thiab avionics. Kuj pom nyob rau hauv kev kho mob thiab kev lag luam sectors thiab industrial systems siv rau lub hwj chim mov filtering, decoupling, thiab sij hawm circuits nyob rau hauv hnyav industrial puag ncig.

Yam ntxwv
Lub CA axial khoom tantalum capacitor yog ib hom cylindrical nrog ob txoj kev tawm los ntawm ob sab sib txawv. Nws tau tsim los ntawm cov khoom siv manganese dioxide electrolyte thiab ua ke nrog lub siab capacitance ceev ntawm tantalum technology nrog rau cov neeg kho tshuab yooj yim ntawm axial los ntawm - qhov mounting. Nws tuaj yeem muab kev ua haujlwm ruaj khov, tsis tshua muaj profile thiab kev ntseeg tau zoo heev rau nruab nrab- mus rau - cov ntawv siv hluav taws xob siab / kev muaj peev xwm thoob plaws kev lag luam, kev lag luam thiab qee cov khoom siv hluav taws xob siab - ntseeg tau.
Polarity:nruj polar (anode / cathode cim kom meej). Lub anode txuas nrog lub sintered tantalum pellet, thaum lub cathode rau cov khoom MnO₂ electrolyte thiab sab nrauv. Reverse voltage ua rau irreversible puas los yog luv luv Circuit Court.
Ultra{0}} Tsawg DC Leakage:Cov khoom MnO₂ electrolyte tshem tawm cov kua electrolyte tsiv teb tsaws, uas ua rau kom qis qis dua li ntub tantalum thiab txhuas electrolytic capacitors -zoo meej rau qis- zog, roj teeb - ua haujlwm, lossis precision analog circuits.
Stable capacitance nyob rau lub sijhawm thiab kub:Negligible capacitance drift (<1%/year under rated conditions); capacitance change ≤±10% across the full -55°C to +125°C.
High Mechanical Robustness:Hermetic sealing thiab rigid axial lead tsim tiv thaiv kev vibration, shock, thiab mechanical stress (ua tau raws li cov qauv kev lag luam / qib tub rog).
Lub neej ua haujlwm ntev:Ntau tshaj lossis sib npaug rau 10,000 teev @ +125℃(tag nrho cov ntsuas hluav taws xob); Ntau dua lossis sib npaug li 200,000 teev @ +85 degree
Tus kheej-Khoom kho mob:Ib qho tseem ceeb ntawm cov khoom siv tantalum technology-yog tias muaj qhov tsis xws luag ntawm dielectric me me tshwm sim, MnO₂ electrolyte tsim ib txheej insulating oxide ntawm qhov chaw tsis xws luag, tiv thaiv luv luv Circuit Court thiab txuas ntxiv lub neej.

FAQ
Q1: Dab tsi yog qhov kev cia zoo rau axial khoom tantalum capacitors?
A1: Nws yuav tsum tau muab khaws cia rau hauv lub ntim ntim thawj zaug raws li hauv qab no.
Kub: -10℃rau +40℃Humidity: Tsawg dua los yog sib npaug rau 70% RH (tsis-condensing)
Khaws kom deb ntawm cov dej noo, cov roj corrosive (sulfur / chlorine), tshav ntuj ncaj qha, lub cev poob siab / kev co, thiab kev sib cuag hlau (tiv thaiv luv luv).
Q2: axial khoom tantalum capacitors puas tuaj yeem siv rau hauv siab - zaus circuits (piv txwv li saum 1MHz)?
A2: Lawv haum rau qis lossis nruab nrab siab zaus (txog 1MHz). axial coaxial lead tsim minimizes parasitic inductance piv rau radial tantalum capacitors.
Q3: Dab tsi yog tus kheej - kho vaj tse ntawm axial khoom tantalum capacitor?
A3: Tus kheej- kho yog qhov tseem ceeb ntawm axial khoom tantalum capacitors. Yog hais tias ib qho me me dielectric txheej tsis zoo tshwm sim zoo li me me tawg, cov khoom MnO₂ electrolyte yuav tam sim ntawd tsim ib qho insulating oxide txheej ntawm qhov chaw tsis xws luag los kaw qhov tsis xws luag thiab tiv thaiv luv luv Circuit Court tsis tshwm sim uas tshem tawm cov teeb meem me me, txo qis qis qis thiab txuas ntxiv lub neej kev pab cuam.
Q4: Yuav ua li cas kuaj axial khoom tantalum capacitor rau kev ua haujlwm li qub?
A4: Ua 3 qhov kev xeem tseem ceeb ntawm 25℃(ib IEC 60384-15) nrog lub ntsuas ntsuas ntsuas / LCR ntsuas:
Kev ntsuas ntsuas: ntsuas tus nqi hauv qhov ntsuas siab (± 10% lossis ± 20%).
DC leakage test: Siv cov ntsuas hluav taws xob rau 5 feeb; leakage tam sim no ua tau raws li cov qauv Tsawg dua lossis sib npaug ntawm 0.01 CR·UR μA / 0.5μA txwv (qhov twg ntau dua).
ESR/DF check: ESR/DF nyob rau hauv datasheet ranges (tsis muaj qhov txawv txav txawv txav - qhia txog kev degradation sab hauv).
