01 Iterambere ryuzuye mu gihe cya 5G: Ibisabwa bishya kuri sitasiyo za 5G Base!
Sitasiyo za 5G zigizwe na BBU (Baseband Unit) na RRU (Remote Radio Unit). RRU ikunze gushyirwa hafi ya antene, ifite fibre optique ihuza BBU na RRU, hamwe n'insinga za coaxial zihuza RRU na antene kugira ngo amakuru yohererezwe. Ugereranyije na 3G na 4G, BBU na RRU muri 5G zigomba gucunga ubwinshi bw'amakuru bwiyongera cyane, hamwe n'umuvuduko mwinshi w'itumanaho biganisha ku gutanga umuriro udahindagurika kuri chips zikora. Ibi bisaba capacitors nke za Equivalent Series Resistance (ESR) zo kuyungurura, gukuraho urusaku, no kwemeza ko umuriro utembera neza.

Muri sitasiyo za 5G, capacitors za YMIN stacked na capacitors za polymer tantalum zitwara imizigo ni ibintu by'ingenzi, bitanga imikorere myiza yo kuyungurura no kwemeza ko ibimenyetso ari byiza. Capacitors za stacked zifite ESR iri hasi cyane ya 3mΩ, ziyungurura neza urusaku ruturuka ku nsinga z'amashanyarazi kugira ngo zihamye ko ibimenyetso bigumaho kandi birusheho kugira ireme n'ubudahangarwa. Hagati aho, capacitors za polymer tantalum zitwara imizigo, bitewe n'imikorere yazo itangaje y'ubushyuhe bwinshi n'ubudahangarwa bw'igihe kirekire, zikwiriye cyane gukoreshwa mu bidukikije bishyuha cyane bya sitasiyo za 5G, zishyigikira kohereza ibimenyetso byihuse kandi zizeza ko itumanaho ryizewe kandi rikora neza. Gukoresha izi capacitors zitwara imizigo ni ingenzi kugira ngo ikoranabuhanga rya 5G rigere ku muvuduko mwinshi kandi rifite ubushobozi bwo hejuru.
A. ESR nkeya (Ubudahangarwa bw'uruhererekane rungana):Capacitors zishyizwe hamwe na capacitors za polymer tantalum zitwara umuriro zifite ESR nkeya cyane, cyane cyane capacitors zishyizwe hamwe zigera kuri ESR nkeya cyane ya 3mΩ. Ibi bivuze ko zishobora kugabanya igihombo cy'ingufu mu gukoresha inshuro nyinshi, kunoza imikorere y'ingufu, no kwemeza imikorere myiza ya sitasiyo za 5G.
B. Ubushobozi bwo kwihanganira amazi ashyushye cyane:Capacitors zifite stacked na capacitors za polymer tantalum zitwara amazi zishobora kwihanganira imigezi minini, zikwiriye guhangana n'ihindagurika ry'umugezi muri sitasiyo za 5G, zitanga ingufu zihamye kandi zigatuma habaho imikorere yizewe mu bihe bitandukanye by'umutwaro.
C. Guhagarara neza cyane:Capacitors zifite stacked na capacitors za polymer tantalum zikoresha amashanyarazi zigaragaza ko zihamye cyane, zigakomeza gukora neza kw'amashanyarazi mu gihe kirekire. Ibi ni ingenzi cyane ku bigo bya 5G bisaba gukora neza igihe kirekire, bikanatuma ibikoresho biramba kandi bikaba byizewe.
03 Umwanzuro
Capacitors za YMIN Stacked polymer solid-state na capacitors za polymer tantalum zitwara umuriro zifite imiterere nka ultra-low ESR, high ripple current tolerance, hamwe na stability iri hejuru. Zikemura neza ibibazo by’amashanyarazi adahindagurika ku mashanyarazi akoreshwa muri 5G base stations, zigatuma ibicuruzwa biramba kandi bikaba byizewe ndetse no mu gihe ubushyuhe bwo hanze buhindagurika. Zitanga icyizere gikomeye cyo guteza imbere no gushyiraho 5G base stations.
