01 Kuvandudzwa Kwakazara Munguva ye5G: Zvinodiwa Zvitsva zve5G Base Stations!
Nzvimbo dze5G base stations dzinosanganisira BBU (Baseband Unit) neRRU (Remote Radio Unit). Iyo RRU inowanzoiswa pedyo neantenna, ine optical fiber inobatanidza BBU neRRU, uye coaxial cables inobatanidza RRU neantenna kuti itumirwe ruzivo. Zvichienzaniswa ne3G ne4G, BBU neRRU mu5G dzinoda kubata data rakawanda zvakanyanya, ne carrier frequency yakakwira zvichikonzera kusagadzikana kwe direct current kuma active chips. Izvi zvinoda ma capacitor eEquivalent Series Resistance (ESR) akaderera ekusefa, kubvisa ruzha, uye kuona kuti current flow yakapfava.
02 YMIN Stacked Capacitors neTantalum Capacitors Vanoita Mabasa Akakosha

Munzvimbo dze5G base, macapacitor eYMIN stacked uye macapacitor epolymer tantalum anofambisa magetsi zvinhu zvakakosha, zvichipa mabasa akanaka ekusefa uye kuona kuti masignal akamira zvakanaka. Macapacitor akasungirirwa ane ESR yakaderera ye3mΩ, achisefa ruzha kubva patambo dzemagetsi kuti ave nechokwadi chekugadzikana uye kuwedzera kunaka uye kugadzikana kwesignal. Panguva imwecheteyo, macapacitor epolymer tantalum anofambisa magetsi, nekuda kwekushanda kwawo kwakanaka uye kugadzikana kwenguva refu, anonyanya kukodzera kushandiswa munzvimbo dzine tembiricha yepamusoro dze5G base stations, achitsigira kutumira masignal nekukurumidza uye kuona kuti kutaurirana kwakavimbika uye kushanda zvakanaka. Kushandiswa kwemacapacitor aya ane simba rakawanda kwakakosha pakuzadzisa kugona kwetekinoroji ye5G nekukurumidza uye kugona kwakakwirira.
A. Low ESR (Kuramba Kwakaenzana Muchikamu):Ma capacitor akaganhurirwa uye ma capacitor e conductive polymer tantalum ane ESR yakaderera zvikuru, kunyanya ma capacitor akaganhurirwa ane ESR yakaderera zvikuru ye3mΩ. Izvi zvinoreva kuti anogona kuderedza kurasikirwa kwesimba mukushandiswa kwema frequency akawanda, kuvandudza mashandiro esimba, uye kuona kuti 5G base stations inoshanda zvakanaka.
B. Kushivirira Kwakanyanya Kwemvura Inoputika:Ma capacitor akarongwa uye ma conductive polymer tantalum capacitors anogona kutsungirira ma ripple currents makuru, akakodzera kubata kushanduka kwemagetsi mu 5G base stations, achipa simba rakagadzikana uye achivimbisa kushanda kwakavimbika pasi pemamiriro akasiyana emutoro.
C. Kugadzikana Kwakanyanya:Ma capacitor akarongwa uye ma conductive polymer tantalum capacitors anoratidza kugadzikana kwakanyanya, achichengetedza mashandiro awo emagetsi kwenguva yakareba. Izvi zvakakosha zvikuru kune 5G base stations dzinoda kushanda kwakasimba kwenguva refu, zvichiita kuti michina igare yakavimbika uye igare kwenguva refu.
03 Mhedziso
Macapacitor eYMIN stacked polymer solid-state capacitors uye macapacitor econductive polymer tantalum ane zvinhu zvakaita se ultra-low ESR, high ripple current tolerance, uye high stability. Anoshanda zvakanaka pakugadzirisa marwadzo emagetsi asina kugadzikana kuma active chips mu 5G base stations, zvichiita kuti chigadzirwa chigare kwenguva refu uye chakavimbika kunyangwe kana tembiricha yekunze ichichinja-chinja. Anopa vimbiso yakasimba yekuvandudzwa nekugadzwa kwe 5G base stations.
