Tsis ntev los no, ntau pab pawg engineering tau tshaj tawm txog kev nce nqi sib txawv, lub sijhawm ua khoom ntev dua, thiab kev hloov pauv ntawm cov khoom siv rau tantalum capacitors thiab multilayer solid-state capacitors. Ib qho keeb kwm yav dhau los yog tias kev loj hlob sai ntawm kev thov rau AI servers tau ua rau muaj kev tso tawm ntawm kev thov rau cov capacitors ua haujlwm siab, yog li ua rau muaj kev kub ntxhov ntawm kev muab khoom thiab kev thov thiab kev hloov pauv ntawm tus nqi (raws li cov ntaub ntawv muaj rau pej xeem thiab cov xwm txheej kev lag luam; kev nce nqi tshwj xeeb thiab lub sijhawm ua khoom nyob ntawm tus neeg muab khoom / project).
Qhov peb yuav tsum tsom mus rau yog—thaum koj ntsib tus nqi thiab kev xa khoom uas cuam tshuam nrog tantalum/multilayer capacitors hauv koj cov haujlwm (cov khoom siv hluav taws xob, kev tswj hwm kev lag luam, cov khoom siv hluav taws xob hauv tsheb, cov khoom siv hluav taws xob, thiab lwm yam), puas muaj lwm txoj hauv kev tswj hwm uas ua tau raws li kev ua haujlwm hluav taws xob thiab kev ntseeg siab: cov khoom siv hluav taws xob aluminium electrolytic capacitors / cov khoom siv hluav taws xob aluminium electrolytic capacitors (yuav tsum tau txheeb xyuas raws li tib yam xwm txheej)?
Tsab xov xwm no muab ib txoj kev txiav txim siab uas rov ua dua tau rau cov haujlwm engineering: nyob rau hauv cov xwm txheej twg nws tsim nyog los soj ntsuam kev hloov pauv, nyob rau hauv cov xwm txheej twg nws tsis pom zoo kom hloov, thiab yuav ua li cas txheeb xyuas cov lus qhia tseem ceeb thiab cov ntsiab lus pov thawj sai sai.
Kev Tshuaj Xyuas Kev Ntsuam Xyuas Ua Ntej Hloov Chaw
Peb lub hauv paus ntsiab lus tseem ceeb yog: kev hloov pauv tsis yog ib qho kev hloov pauv nyuaj, tab sis yog ib qho txheej txheem uas ua kom ruaj khov tus nqi thiab kev xa khoom thaum ua tau raws li kev ua haujlwm hluav taws xob thiab kev ntseeg tau. Yog li ntawd, kev ntsuam xyuas qhov project yog qhov tsim nyog ua ntej xaiv cov capacitors.
1. Tsim Nyog Rau Kev Ntsuam Xyuas Hloov Chaw (Qhov Tseem Ceeb Tshaj)
Kev xav tau tus nqi qis + Kev xa khoom raws li qhov xav tau: Xav kom txo cov nqi BOM thiab kev pheej hmoo ntawm kev xa khoom.
Tsis yog raug txwv los ntawm "qhov loj me/qhov siab txwv," tab sis tseem xav tau ESR qis/kev tiv thaiv ripple/lub neej ntev.
Cov Chaw Ib Txwm Muaj (Piv txwv, raws li topology): Cov chaw lim dej fais fab/cov chaw khaws cia hluav taws xob, kev lim dej DC-DC tso zis, kev sib cais/kev khaws cia hluav taws xob ntawm theem board, kev lim dej ntawm lub tsheb npav, thiab lwm yam.

1. Kev Txwv Qhov Chaw/Qhov Siab (Tsuas Yog Cov Pob Khoom Uas Muaj Ultra-Thin Xwb)
2. Cov Kev Txwv Muaj Zog Ntawm "Kev Txwv Tsis Pub Muaj Zaus Siab/Kev Txwv ESR" (Tshwj xeeb tshaj yog nyob rau hauv MHz Ntau); Cov Neeg Siv Khoom/Platform Cov Naj Npawb Qhia Txog Qhov Chaw lossis Daim Ntawv Pov Thawj Xauv Rau Hauv
Vim li cas Capacitor "Qauv" cuam tshuam rau cov yam ntxwv ntawm cov khoom siv?
Tantalum capacitors: Kev ua haujlwm volumetric siab heev, tsim nyog rau cov qauv tsim uas txwv qhov chaw; txawm li cas los xij, cov saw hlau muab khoom muaj kev cuam tshuam ntau dua rau cov khoom siv raw thiab kev hloov pauv ntawm kev ua lag luam.
Cov capacitors solid-state ntau txheej: ESR qis, muaj peev xwm ripple muaj zog, thiab kev ua haujlwm siab zaus zoo heev; txawm li cas los xij, muaj cov teeb meem txheej txheem siab, thiab qhov kev thov siab tshaj plaws yuav ua rau muaj kev nyuaj siab rau kev muab khoom.
Cov capacitors electrolytic aluminium solid-state / hybrid solid-liquid aluminium electrolytic capacitors: Raws li cov qauv winding laus thiab cov ntaub ntawv ua los ntawm txhuas, cov nqi tuaj yeem tswj tau ntau dua, thiab muaj kev sib npaug zoo dua hauv kev siv tau ntev, kev ruaj khov ntawm qhov kub thiab txias, thiab kev siv nyiaj tag nrho (kev sib piv yuav tsum yog raws li kev txheeb xyuas hauv tib qho xwm txheej).
