01 Kev Txhim Kho Kom Zoo Hauv 5G Era: Cov Kev Cai Tshiab Rau 5G Base Stations!
5G chaw nres tsheb muaj BBU (Baseband Unit) thiab RRU (Remote Radio Unit). RRU feem ntau nyob ze rau lub antenna, nrog rau fiber ntau txuas BBU thiab RRU, thiab cov xov hlau coaxial txuas RRU thiab antenna rau kev xa cov ntaub ntawv. Piv rau 3G thiab 4G, BBU thiab RRU hauv 5G yuav tsum tau tswj cov ntaub ntawv ntau ntxiv, nrog rau cov zaus nqa khoom siab dua ua rau tsis ruaj khov ntawm cov khoom siv hluav taws xob ncaj qha rau cov chips nquag. Qhov no xav tau cov capacitors Equivalent Series Resistance (ESR) qis rau kev lim dej, tshem tawm suab nrov, thiab xyuas kom meej tias cov dej ntws du.

Hauv 5G chaw nres tsheb, YMIN stacked capacitors thiab conductive polymer tantalum capacitors yog cov khoom tseem ceeb, muab cov haujlwm lim dej zoo heev thiab ua kom muaj kev ncaj ncees ntawm lub teeb liab. Stacked capacitors muaj ESR qis heev ntawm 3mΩ, lim cov suab nrov tawm ntawm cov xov hluav taws xob kom ntseeg tau tias muaj kev ruaj khov thiab txhim kho qhov zoo thiab kev ruaj khov ntawm lub teeb liab. Lub caij no, conductive polymer tantalum capacitors, vim lawv qhov kev ua tau zoo hauv qhov kub thiab txias thiab kev ruaj khov mus sij hawm ntev, yog qhov tsim nyog rau kev siv hauv qhov chaw kub thiab txias ntawm 5G chaw nres tsheb, txhawb nqa kev xa xov tooj cua ceev ceev thiab ua kom muaj kev ntseeg siab thiab kev sib txuas lus zoo. Kev siv cov capacitors ua tau zoo no yog qhov tseem ceeb rau kev ua tiav qhov ceev ceev, muaj peev xwm siab ntawm 5G thev naus laus zis.
A. ESR qis (Kev tiv thaiv sib npaug):Cov stacked capacitors thiab conductive polymer tantalum capacitors muaj ESR qis heev, tshwj xeeb tshaj yog cov stacked capacitors uas ua tiav ultra-low ESR ntawm 3mΩ. Qhov no txhais tau tias lawv tuaj yeem txo qhov poob zog hauv cov ntawv thov zaus siab, txhim kho kev siv hluav taws xob zoo, thiab xyuas kom meej tias 5G chaw nres tsheb ua haujlwm tau zoo.
B. Kev kam rau siab tam sim no:Cov capacitors sib dhos thiab cov polymer tantalum capacitors conductive tuaj yeem tiv taus cov dej ntws loj, tsim nyog rau kev tswj cov kev hloov pauv tam sim no hauv 5G chaw nres tsheb, muab cov zis hluav taws xob ruaj khov thiab ua kom muaj kev ua tau zoo txhim khu kev qha nyob rau hauv cov xwm txheej sib txawv.
C. Kev Ruaj Ntseg Siab:Cov capacitors sib dhos thiab cov polymer tantalum capacitors ua rau pom tias muaj kev ruaj khov siab, tswj lawv cov kev ua haujlwm hluav taws xob tau ntev. Qhov no tseem ceeb heev rau 5G chaw nres tsheb uas xav tau kev ua haujlwm ruaj khov mus sij hawm ntev, ua kom ntseeg tau tias cov khoom siv ntseeg tau thiab siv tau ntev.
03 Xaus Lus
Cov YMIN stacked polymer solid-state capacitors thiab conductive polymer tantalum capacitors muaj cov yam ntxwv xws li ultra-low ESR, high ripple current tolerance, thiab high stability. Lawv ua tau zoo daws cov teeb meem ntawm kev tsis ruaj khov fais fab rau cov active chips hauv 5G base stations, ua kom cov khoom siv tau ntev thiab kev ntseeg siab txawm tias nyob rau hauv qhov kub thiab txias sab nraum zoov. Lawv muab kev ntseeg siab rau kev tsim thiab tsim cov 5G base stations.
