A CA42 dipped tantalum capacitor uas tsim los ntawm BEC yog ib qho kev txhim khu kev qha, los ntawm -qhov hluav taws xob capacitor los ntawm kev siv tantalum hlau rau kev ua haujlwm siab. Nws yog qhov tshwj xeeb rau kev ua haujlwm ruaj khov, tsis tshua muaj to thiab lub neej ntev. Nws yog encapsulated nyob rau hauv nplaim taws-retardant epoxy rau kev tiv thaiv. Txawm hais tias txawm tias - cov ntawv thov lub qhov tau tsawg thiab tsawg dua hauv kev lag luam niaj hnub no, nws tseem yog qhov zoo tagnrho rau kev lim dej, kev sib cais, thiab cov khoom siv hluav taws xob hauv hluav taws xob xws li TVs, khoos phis tawj, thiab cov khoom siv kho mob. Koj tuaj yeem pom nws hauv kev lag luam hauv xov tooj thiab tub rog. Raws li nws muaj sab zoo thiab tsis zoo, nws yuav tsum tau ceev faj thaum siv. Yuav muaj cov cim tseem ceeb ntawm lub cev los qhia qhov twg yog qhov zoo.

Yam ntxwv
High Capacitance Ceev:Zoo ib yam li lwm yam tantalum capacitor, lawv muab cov peev txheej siab rau ib chav tsev ntim hauv qhov dhau los ntawm - hom.
Stable Parameters:Zoo capacitance stability nyob rau hauv ntau qhov kub thiab txias (feem ntau -55℃rau +125 degree) thiab tsis tshua muaj to tam sim no (zoo tshaj rau polymer tantalum capacitors nyob rau hauv no hais txog).
Zaus teb:Nruab nrab ESR thiab impedance. Kev ua tau zoo degrades ntawm ntau zaus (MHz + ntau) vim yog cov hlau lead inductance thiab kev tsim kho sab hauv. Tsis zoo li qis -ESR nto-mount counterparts.
Voltage Ntau:Feem ntau muaj nyob rau hauv qis mus rau nruab nrab voltage ranges, feem ntau ntawm 2.5V txog 50VDC. Siab voltages dua li hom polymer sib npaug.
Kev kub siab dav:Feem ntau ntsuas rau -55℃rau +125℃kev ua haujlwm yam tsis muaj kev puas tsuaj loj.
Moisture Resistance:Lub epoxy txheej muab kev tiv thaiv zoo tiv thaiv cov av noo thiab kev ntxhov siab me me.
Lub neej ntev txee:Tsis muaj degradation nyob rau hauv cia thaum khaws cia nyob rau hauv ib puag ncig tej yam kev mob.

FAQ
Q1: Dab tsi yog qhov capacitance thiab voltage ntau?
A1: Feem ntau capacitance ranges ntawm 0.1µF txog 0µF. Feem ntau qhov kev ntsuas hluav taws xob ntau ntawm 2.5V txog 50V DC, nrog qee qhov tshwj xeeb txog li 100V (tsis tshua pom). Ntau dua capacitance feem ntau tuaj nyob rau hauv cov ntaub ntawv loj dua.
Q2: Vim li cas ESR tus nqi siab dua li ntawm polymer tantalum capacitor?
A2: Cov cathode yog manganese dioxide (MnO₂), uas muaj hluav taws xob tsawg dua li cov khoom siv hluav taws xob siv hauv polymer tantalum capacitors. Qhov no ua rau ESR siab dua.
Q3: Yuav ua li cas ruaj khov yog qhov capacitance tshaj qhov kub thiab txias.
A3: ruaj khov heev. Kev kam rau siab yog ± 10% tshaj -55℃rau +125℃. Lawv muaj kev laus tsis zoo (tsis zoo li MLCCs) thiab tsis qhuav -tawm (tsis zoo li txhuas electrolytics), ua rau muaj kev ruaj ntseg mus ntev.
Q4: Lawv zoo li cas thaum lawv ua tsis tiav?
A4: Hauv kev puas tsuaj loj, cov epoxy txheej tuaj yeem tawg, ua pa nrog pa taws / nplaim taws, lossis tawg. Hauv cov xwm txheej tsawg dua, luv -circuit yuav tshwm sim. Txhua zaus tshuaj xyuas qhov tawg, tawg, lossis bulging epoxy coat.
Q5: Lawv puas muaj lub txee lub neej lossis kev cia khoom?
A5: Lawv muaj lub neej txee zoo heev (ntau xyoo) yog tias khaws cia rau hauv qhov chaw txias, qhuav. Txawm li cas los xij, epoxy tuaj yeem nqus dej noo. Yog tias raug cov av noo siab, ua raws li cov chaw tsim khoom ntawm Moisture Sensitivity Level (MSL) cov lus qhia, uas yuav tsum tau ci ua ntej reflow (yog siv nyob rau hauv ib tug reflow txheej txheem rau mix-technology boards).
