Tambaya: 5. Ta yaya YMIN's m-liquid hybrid capacitors ke ba da garantin dogaro na dogon lokaci tare da tsawon rayuwar sama da sa'o'i 4000 a 135°C?
A: YMIN capacitors suna amfani da kayan polymer tare da juriya mai zafi mai zafi, cikakkiyar gwajin CCD, da gwajin tsufa (135 ° C daidai yake da kimanin sa'o'i 30,000 a 105 ° C) don tabbatar da aikin barga a cikin yanayin zafi mai zafi kamar sassan injin.
Q:6. Menene kewayon bambancin ESR na YMIN m-ruwa matasan capacitors bayan sake kwarara soldering? Ta yaya ake sarrafa tudu?
A: Bambancin ESR da aka auna na capacitors YMIN shine ≤0.002Ω (misali, 0.0078Ω → 0.009Ω). Wannan shi ne saboda m-ruwa tsarin hybrid tsarin danne high-zazzabi bazuwar na electrolyte, da kuma hada stitching tsari tabbatar da barga electrode lamba.
Q:7. Ta yaya za a zaɓi capacitors don rage yawan amfani da wutar lantarki a cikin da'irar tace shigarwar OBC?
A: YMIN ƙananan-ESR ƙira (misali, VHU_35V_270μF, ESR ≤8mΩ) an fi so don rage asarar matakan shigar da bayanai. A lokaci guda, yayyo halin yanzu ya kamata ya zama ≤20μA don guje wa ƙara yawan ƙarfin jiran aiki.
Q:8. Menene fa'idodin YMIN capacitors tare da babban ƙarfin ƙarfin ƙarfi (misali, VHT_25V_470μF) a cikin matakin ƙa'idar fitarwa na DCDC?
A: High capacitance rage fitarwa ripple ƙarfin lantarki da lowers da bukatar m tace. Ƙaƙƙarfan ƙira (10 × 10.5mm) yana gajarta alamun PCB kuma yana rage ƙarin asara ta hanyar inductance parasitic.
Tambaya: 9. Shin YMIN capacitor sigogi za su shuɗe kuma su shafi amfani da wutar lantarki a ƙarƙashin yanayin girgizar-aji na mota?
A: YMIN capacitors suna amfani da ƙarfafa tsarin (kamar ƙirar lantarki na ciki) don tsayayya da girgiza. Gwaji ya nuna cewa ESR da ɗigogi na sauye-sauye na halin yanzu bayan girgiza bai wuce 1% ba, yana hana lalacewar aiki saboda damuwa na inji.
Q: 10. Menene buƙatun shimfidar wuri don YMIN capacitors yayin aikin 260°C na sake kwararar siyarwar?
A: Ana ba da shawarar cewa capacitors su kasance ≥5mm nesa da abubuwan da ke haifar da zafi (kamar MOSFETs) don guje wa wuce gona da iri. Ana amfani da ƙira mai ma'auni mai ma'aunin solder ƙirar ƙira don rage yawan damuwa mai zafi yayin hawa.
Tambaya: 11. Shin YMIN m-ruwa hybrid capacitors sun fi tsada fiye da na gargajiya na lantarki capacitors?
A: YMIN capacitors suna ba da tsawon rayuwa (135 ° C / 4000h) da ƙarancin amfani da wutar lantarki (ceton farashin tsarin sanyaya), rage ƙimar rayuwar rayuwar na'urar gabaɗaya sama da 10%.
Q:12. Shin YMIN na iya samar da sigogi na musamman (kamar ƙananan ESR)?
A: iya. Za mu iya daidaita tsarin lantarki dangane da mitar sauyawa na abokin ciniki (misali, 100kHz-500kHz) don ƙara rage ESR zuwa 5mΩ, saduwa da buƙatun OBC masu inganci.
Q:13. Shin YMIN's ƙwararrun masu samar da wutar lantarki masu ƙarfi suna goyan bayan dandamali masu ƙarfi na 800V? Wadanne samfuri ne shawarar?
A: iya. Jerin VHT yana da matsakaicin juriya na ƙarfin lantarki na 450V (misali, VHT_450V_100μF) da ƙyalli na yanzu na ≤35μA. An yi amfani da shi a cikin kayayyaki na DC-DC don yawancin motocin 800V.
Q:14. Ta yaya YMIN's m-liquid hybrid capacitors ke inganta yanayin wutar lantarki a cikin da'irori na PFC?
A: Low ESR yana rage hasara mai yawa, yayin da ƙananan ƙimar DF (≤1.5%) yana kashe asarar dielectric, yana haɓaka ingantaccen matakin PFC zuwa ≥98.5%.
Q:15. Shin YMIN yana ba da ƙirar tunani? Ta yaya zan iya samun su?
A: OBC/DCDC ikon topology tunani ɗakin karatu (ciki har da simulation model da PCB layout jagororin) yana samuwa a kan mu official website. Yi rijistar asusun injiniya don zazzage shi.
