Cov kws ua haujlwm engineers, nej puas tau ntsib hom kev ua tsis tiav "phantom" no? Ib lub data center gateway uas tsim tau zoo tau sim zoo heev hauv chav kuaj, tab sis tom qab ib lossis ob xyoos ntawm kev xa tawm ntau thiab kev ua haujlwm hauv thaj chaw, cov pawg tshwj xeeb tau pib muaj kev poob pob khoom uas tsis piav qhia, hluav taws xob tsis ua haujlwm, thiab txawm tias rov pib dua. Pab pawg software tau tshawb xyuas cov lej kom zoo, thiab pab pawg kho vajtse tau kuaj xyuas ntau zaus, thaum kawg siv cov cuab yeej precision los txheeb xyuas qhov ua rau muaj teeb meem: suab nrov nrov ntawm lub zog tseem ceeb.
YMIN Multilayer Capacitor Kev daws teeb meem
- Kev Tshawb Fawb Txog Qhov Ua Rau Muaj Teeb Meem - Cia peb kawm tob txog qhov "kev tshawb fawb txog kab mob" hauv qab no. Kev siv hluav taws xob ntawm CPU/FPGA chips hauv cov rooj vag niaj hnub no hloov pauv ntau heev, ua rau muaj ntau qhov sib xyaw ua ke ntawm cov hluav taws xob tam sim no. Qhov no yuav tsum tau lawv cov tes hauj lwm sib cais hluav taws xob, tshwj xeeb tshaj yog cov capacitors loj, kom muaj qhov tsis kam sib npaug (ESR) qis heev thiab muaj peev xwm tam sim no siab. Txoj kev ua tsis tiav: Nyob rau hauv kev ntxhov siab ntev ntawm qhov kub thiab txias thiab tam sim no siab, qhov sib txuas ntawm electrolyte-electrode ntawm cov polymer capacitors ib txwm poob qis, ua rau ESR nce ntxiv ntau dhau sijhawm. ESR nce ntxiv muaj ob qho txiaj ntsig tseem ceeb: Txo qhov ua tau zoo ntawm kev lim dej: Raws li Z = ESR + 1/ωC, ntawm cov zaus siab, impedance Z feem ntau yog txiav txim siab los ntawm ESR. Thaum ESR nce ntxiv, lub peev xwm ntawm lub capacitor los tswj cov suab nrov zaus siab tsis muaj zog heev. Kev ua kom sov tus kheej ntau ntxiv: Ripple tam sim no tsim cua sov thoob plaws ESR (P = I²_rms * ESR). Qhov kub nce ntxiv no ua rau kev laus sai dua, tsim kom muaj lub voj voog rov qab zoo uas thaum kawg ua rau lub capacitor tsis ua haujlwm ua ntej lub sijhawm. Qhov tshwm sim: Lub capacitor array uas tsis ua haujlwm yuav tsis muaj peev xwm muab hluav taws xob txaus thaum lub sijhawm hloov pauv ntawm lub zog, thiab nws kuj tsis tuaj yeem lim tawm cov suab nrov siab uas tsim los ntawm lub zog hloov pauv. Qhov no ua rau muaj qhov tsis zoo thiab poob qis hauv lub zog hluav taws xob ntawm lub nti, ua rau muaj qhov yuam kev logic.
- YMIN Cov Kev Dais Teeb Meem thiab Cov Txiaj Ntsig ntawm Cov Txheej Txheem - YMIN's MPS series multilayer solid-state capacitors yog tsim los rau cov kev siv uas xav tau ntau yam no.
Kev tsim kho tshiab: Cov txheej txheem ntau txheej sib xyaw ua ke ntau lub capacitor me me hauv ib pob. Cov qauv no tsim cov nyhuv impedance sib piv rau ib lub capacitor loj, txo qis ESR thiab ESL (sib npaug series inductance) mus rau qib qis heev. Piv txwv li, MPS 470μF / 2.5V capacitor muaj ESR qis li qis dua 3mΩ.
Kev Lav Khoom Siv: Lub kaw lus polymer khov kho. Siv cov polymer khov kho uas ua rau muaj hluav taws xob, nws tshem tawm qhov kev pheej hmoo ntawm kev xau thiab muaj cov yam ntxwv zoo heev ntawm qhov kub thiab zaus. Nws cov ESR hloov pauv tsawg kawg nkaus ntawm ntau qhov kub thiab txias (-55 ° C txog + 105 ° C), uas daws qhov teeb meem ntawm lub neej ntawm cov kua / gel electrolyte capacitors.
Kev Ua Tau Zoo: ESR qis heev txhais tau tias muaj peev xwm tswj tau tam sim no ntau dua, txo qhov kub sab hauv nce siab, thiab txhim kho MTBF (lub sijhawm nruab nrab ntawm kev ua tsis tiav). Cov lus teb siab zoo heev lim tawm cov suab nrov hloov pauv MHz, muab cov hluav taws xob huv rau lub nti.
Peb tau ua qhov kev ntsuam xyuas sib piv ntawm cov neeg siv khoom lub motherboard uas tsis zoo:
Kev sib piv ntawm cov duab nthwv dej: Hauv qab tib lub nra hnyav, qib suab nrov ntawm lub zog hluav taws xob qub tau nce mus txog 240mV. Tom qab hloov cov capacitors YMIN MPS, lub suab nrov tau raug txo kom tsawg dua 60mV. Lub oscilloscope waveform qhia meej meej tias lub zog hluav taws xob waveform tau du thiab ruaj khov.
Kev ntsuas kub nce: Nyob rau hauv tag nrho cov load ripple tam sim no (kwv yees li 3A), qhov kub ntawm qhov chaw ntawm cov capacitors ib txwm tuaj yeem ncav cuag tshaj 95 ° C, thaum qhov kub ntawm qhov chaw ntawm YMIN MPS capacitors tsuas yog nyob ib puag ncig 70 ° C, qhov kub nce txo qis tshaj 25 ° C. Kev sim lub neej ceev: Ntawm qhov kub ntsuas ntawm 105 ° C thiab ntsuas ripple tam sim no, tom qab 2000 teev, qhov peev xwm khaws cia tus nqi tau mus txog > 95%, ntau tshaj qhov tus qauv kev lag luam.
- Cov Xwm Txheej Siv thiab Cov Qauv Pom Zoo - YMIN MPS Series 470μF 2.5V (Qhov Loj: 7.3 * 4.3 * 1.9mm). Lawv cov ESR qis heev (<3mΩ), qhov ntsuas tam sim no siab, thiab qhov kub ua haujlwm dav (105 ° C) ua rau lawv yog lub hauv paus txhim khu kev qha rau cov qauv tsim hluav taws xob tseem ceeb hauv cov khoom siv sib txuas lus hauv network siab, cov servers, cov kab ke khaws cia, thiab cov motherboard tswj kev lag luam.

Rau cov neeg tsim khoom siv kho vajtse uas xav kom muaj kev ntseeg siab tshaj plaws, kev sib cais cov khoom siv fais fab tsis yog ib qho teeb meem ntawm kev xaiv tus nqi capacitance kom raug xwb; nws yuav tsum tau ua tib zoo saib xyuas cov yam ntxwv dynamic xws li ESR ntawm lub capacitor, ripple current, thiab kev ruaj khov mus sij hawm ntev. YMIN MPS multilayer capacitors, los ntawm cov thev naus laus zis tshiab thiab cov khoom siv, muab cov engineers nrog lub cuab yeej muaj zog rau kev kov yeej cov teeb meem suab nrov ntawm cov khoom siv fais fab. Peb vam tias qhov kev tshuaj xyuas tob tob no yuav muab kev nkag siab rau koj. Yog xav paub txog cov teeb meem ntawm kev siv capacitor, tig mus rau YMIN.
