01 Ukuthuthukiswa Okuphelele Esikhathini se-5G: Izidingo Ezintsha Zeziteshi Eziyisisekelo ze-5G!
Iziteshi eziyisisekelo ze-5G zihlanganisa i-BBU (Baseband Unit) ne-RRU (Remote Radio Unit). I-RRU ivamise ukubekwa eduze kwe-antenna, ine-optical fibre exhuma i-BBU ne-RRU, kanye namakhebuli angama-coaxial axhuma i-RRU kanye ne-antenna ukuze kudluliselwe ulwazi. Uma kuqhathaniswa ne-3G ne-4G, i-BBU ne-RRU ku-5G idinga ukuphatha amavolumu edatha anyuswe ngokuphawulekayo, ngamafrikhwensi aphezulu enkampani yenethiwekhi aholela ekunikezeni okungazinzile kwamandla aqondile kuma-chips asebenzayo. Lokhu kudinga ama-capacitor aphansi we-Equivalent Series Resistance (ESR) ukuze ahlunge, asuse umsindo, futhi aqinisekise ukugeleza kwamanje okushelelayo.
02 YMIN Ama-Capacitor Astakiwe kanye nama-Tantalum Capacitors Adlala Izindima Ezibalulekile

Eziteshini eziyisisekelo ze-5G, ama-capacitor astakiwe e-YMIN kanye nama-polymer tantalum capacitor ayizingxenye ezibalulekile, ezihlinzeka ngemisebenzi emihle kakhulu yokuhlunga kanye nokuqinisekisa ubuqotho besignali. Ama-capacitor astakiwe ane-ESR ephansi kakhulu engu-3mΩ, ehlunga ngokuphumelelayo umsindo ezintanjeni zamandla ukuze kuqinisekiswe ukuzinza nokuthuthukisa ikhwalithi nokuzinza kwesignali. Phakathi naleso sikhathi, ama-capacitor e-polymer tantalum asebenzayo, ngenxa yokusebenza kwawo okuvelele kokushisa okuphezulu nokuzinza kwesikhathi eside, afaneleka ngokukhethekile ukusetshenziswa ezindaweni ezisezingeni eliphezulu zeziteshi eziyisisekelo ze-5G, ezisekela ukudluliswa kwesignali ngesivinini esiphezulu nokuqinisekisa ukwethembeka kokuxhumana nokusebenza kahle. Ukusetshenziswa kwalawa ma-capacitor asebenza kahle kubalulekile ekuzuzeni isivinini esikhulu, amakhono aphezulu wobuchwepheshe be-5G.
A. I-ESR Ephansi (Equivalent Series Resistance):Ama-capacitor astakiwe kanye nama-polymer tantalum capacitor aqhubayo ane-ESR ephansi kakhulu, ikakhulukazi ama-capacitor astakiwe athola i-ESR ephansi kakhulu engu-3mΩ. Lokhu kusho ukuthi banganciphisa ukulahlekelwa kwamandla ezinhlelweni zokusebenza ze-high-frequency, bathuthukise ukusebenza kahle kwamandla, futhi baqinisekise ukusebenza kahle kweziteshi eziyisisekelo ze-5G.
B. High Ripple Current Tolerance:Ama-capacitor astakiwe kanye nama-polymer tantalum capacitor aqhubayo angamelana nokugeleza kwamanzi amakhulu, alungele ukuphatha ukushintshashintsha kwamanje eziteshini eziyisisekelo ze-5G, ehlinzeka ngokuphuma kwamandla okuzinzile nokuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo ezihlukene zomthwalo.
C. Ukuzinza Okuphezulu:Ama-capacitor astakiwe kanye nama-polymer tantalum capacitor akhombisa ukuzinza okuphezulu, agcina ukusebenza kwawo kukagesi isikhathi eside. Lokhu kubaluleke kakhulu eziteshini eziyisisekelo ze-5G ezidinga ukusebenza okuzinzile kwesikhathi eside, ukuqinisekisa ukwethembeka kwemishini nokuphila isikhathi eside.
03 Isiphetho
Ama-capacitor e-polymer stacked polymer solid-state kanye nama-conductive polymer tantalum capacitor anezici ezifana ne-ultra-low ESR, ukubekezelelana okuphezulu kwamanje, nokuzinza okuphezulu. Babhekana ngokuphumelelayo nezindawo ezibuhlungu zokunikezwa kwamandla okungazinzile kuma-chips asebenzayo eziteshini eziyisisekelo ze-5G, ziqinisekisa impilo ende yomkhiqizo nokuthembeka ngisho nangaphansi kokuguquguquka kwezinga lokushisa ngaphandle. Banikeza isiqinisekiso esiqinile sokuthuthukiswa nokusungulwa kweziteshi eziyisisekelo ze-5G.
