CA55 conductive polymer SMD tantalum capacitor uas tsim los ntawm BEC yog ib qho kev ua haujlwm siab -cov khoom siv hluav taws xob uas siv cov sintered tantalum anode thiab cov khoom siv polymer zoo li cathode. Ntawm lub hauv paus, cov tsoos MnO₂ khoom electrolyte yog hloov los ntawm ib tug conductive polymer electrolyte, nyob rau hauv thiaj li yuav ua tau li ESR tsawg dua qhov tseem ceeb. Nyob rau lub sijhawm no, kev tuav pov hwm tam sim no zoo dua, cov lus teb sai dua thiab txhim kho kev ruaj ntseg kom paub tseeb tias cov khoom siv hluav taws xob no ua lub luag haujlwm tseem ceeb hauv kev lim fais fab, decoupling thiab siab - cov ntawv thov zaus hauv ntau daim ntawv thov. High volumetric efficiency ntawm tantalum yog ua ke nrog lub superior hluav taws xob khoom ntawm polymer cathodes, thiab lawv muaj peev xwm muab ntau dua capacitance nyob rau hauv kuj me me pob. Lawv tuaj yeem siv rau hauv kev lag luam ntawm tsheb, kev sib txuas lus thiab kev ruaj ntseg, kuj pom nyob rau hauv computers thiab xov tooj ntawm tes.

Yam ntxwv
Ultra low ESR thiab siab capacitance ceev:ESR qhov tseem ceeb ntawm 1 ~ 30mΩ ntawm 120 kHz / 25 degree, li ntawm 10 ~ 100 npaug qis dua li ib txwm MnO₂ tantalum capacitors. ESR tseem nyob ruaj khov los ntawm nruab nrab - mus rau - siab zaus (txog 5 MHz) thiab tag nrho cov kev khiav hauj lwm kub ntau yam. Khaws cov capacitance ntau dua rau ib chav tsev ntim.
High RMS Ripple Tam sim no tuav:Qhov qis ESR tshem tawm cov hluav taws kub ntau dhau thiab txhawb nqa kev ua haujlwm siab - tam sim no hauv DC - DC converters thiab fais fab.
2 ~ 5 npaug siab dua qhov kev ntsuas tam sim no dua li qhov sib npaug MnO₂ tantalum capacitors.
Stable Capacitance thiab ESR:Qhov tsawg kawg nkaus capacitance hloov thiab ESR variation ntawm voltage, kub thiab lifespan. Tsis muaj kev puas tsuaj tseem ceeb tom qab thermal cycling lossis ntev - siv sijhawm.

FAQ
Q1: Puas muaj tseeb tias lub polymer tantalum capacitor yeej tsis hlawv?
A1: Lawv muaj ntau yam kev nyab xeeb tsis ua hauj lwm (feem ntau qhib Circuit Court lossis siab tiv thaiv luv luv) thiab tsis ua rau thermal runaway zoo li MnO₂, yog li lawv muaj kev pheej hmoo tsawg dua ntawm kev kub hnyiab. Tab sis lawv yuav tseem overheated nyob rau hauv tej yam huab cua.
Q2: Yog hais tias ib tug polymer tantalum capacitor tseem xav tau derating ntawm voltage?
A2: Txawm hais tias lub polymer tantalum capacitor muaj qhov pheej hmoo ntawm kev kub hnyiab, txawm li cas los xij, derating tseem yog qhov tseem ceeb rau kev ntseeg ntev ntev. Ib txwm ua raws li cov neeg tsim khoom 'surge thiab voltage derating cov lus qhia (feem ntau 50% lossis 70% ntawm cov ntsuas hluav taws xob).
Q3: Dab tsi yuav yog qhov laj thawj tseem ceeb ntawm kev ua tsis tiav ntawm polymer tantalum capacitors?
A3: Cov laj thawj hauv qab no tuaj yeem ua rau tsis ua haujlwm.
1. Voltage surges / spikes tshaj lub capacitor surge ntsuam xyuas.
2. Ntau dhau ripple tam sim no dhau qhov tshwj xeeb, ua rau overheat.
3. Rov qab voltage lossis ntau dhau AC voltage tivthaiv.
4. Mechanical lossis thermal stress thaum lub sij hawm sib dhos (piv txwv li, kev xaiv nruj heev-thiab- qhov chaw, teeb meem rov qab).
