Q1. Kodi ma capacitor a YMIN a solid-liquid hybrid capacitors amalimbana bwanji ndi kugwiritsa ntchito mphamvu mopitirira muyeso chifukwa cha kuchuluka kwa mphamvu yotuluka pambuyo pa kusungunukanso kwa magetsi?
A: Mwa kukonza kapangidwe ka filimu ya oxide kudzera mu polymer hybrid dielectric, timachepetsa kuwonongeka kwa kutentha panthawi yothira soldering (260°C), kusunga mphamvu yotuluka mpaka ≤20μA (avereji yoyezedwa ndi 3.88μA yokha). Izi zimaletsa kutayika kwa mphamvu yogwira ntchito chifukwa cha kuchuluka kwa mphamvu yotuluka ndipo zimaonetsetsa kuti mphamvu yonse ya dongosolo ikukwaniritsa muyezo.
Q2. Kodi ma capacitor a YMIN otsika kwambiri a ESR solid-liquid hybrid capacitors amachepetsa bwanji kugwiritsa ntchito mphamvu mu machitidwe a OBC/DCDC?
A: Kutsika kwa ESR kwa YMIN kumachepetsa kwambiri kutayika kwa kutentha kwa Joule komwe kumachitika chifukwa cha ripple current mu capacitor (njira yotaya mphamvu: Ploss = Iripple² × ESR), zomwe zimapangitsa kuti kusintha kwa makina onse kukhale bwino, makamaka pakusintha kwa DCDC pafupipafupi.
Q3. N’chifukwa chiyani mphamvu yotuluka imakonda kuwonjezeka mu ma capacitor achikhalidwe a electrolytic pambuyo pothira soldering?
A: Ma electrolyte amadzimadzi omwe ali mu ma capacitor achikhalidwe a electrolytic amasanduka nthunzi mosavuta akamatenthedwa kwambiri, zomwe zimapangitsa kuti filimu ya oxide ikhale ndi zolakwika. Ma capacitor olimba amadzimadzi amagwiritsa ntchito zinthu zolimba za polymer, zomwe sizimatentha kwambiri. Kuwonjezeka kwapakati kwa mphamvu yotuluka pambuyo pa 260°C reflow soldering ndi 1.1μA yokha (deta yoyezedwa).
Q: 4. Kodi mphamvu yotulutsira madzi ya 5.11μA itatha kusungunukanso mu deta yoyesera ya ma capacitor a YMIN a solid-liquid hybrid capacitors ikukwaniritsabe malamulo a magalimoto?
A: Inde. Malire apamwamba a leakage current ndi ≤94.5μA. Mtengo wapamwamba kwambiri woyesedwa wa 5.11μA wa ma capacitor a YMIN a solid-liquid hybrid uli pansi kwambiri pa malire awa, ndipo zitsanzo zonse 100 zapambana mayeso okalamba a dual-channel.
Q: 5. Kodi ma capacitor a YMIN opangidwa ndi madzi olimba amatsimikiza bwanji kudalirika kwa nthawi yayitali ndi moyo wa maola opitilira 4000 pa 135°C?
A: Ma capacitor a YMIN amagwiritsa ntchito zipangizo za polima zomwe zimakhala ndi kukana kutentha kwambiri, kuyesa kwathunthu kwa CCD, komanso kuyesa kukalamba mwachangu (135°C ndi ofanana ndi maola pafupifupi 30,000 pa 105°C) kuti zitsimikizire kuti zikugwira ntchito bwino m'malo otentha kwambiri monga zipinda zamainjini.
Q:6. Kodi ma capacitor a YMIN solid-liquid hybrid capacitors ali ndi ESR yotani pambuyo pa reflow soldering? Kodi drift imayendetsedwa bwanji?
A: Kusiyanasiyana kwa ESR komwe kumayesedwa kwa ma capacitor a YMIN ndi ≤0.002Ω (monga, 0.0078Ω → 0.009Ω). Izi zili choncho chifukwa kapangidwe ka solid-liquid hybrid kamaletsa kuwonongeka kwa electrolyte kutentha kwambiri, ndipo njira yosokera pamodzi imatsimikizira kukhudzana kokhazikika kwa electrode.
Q:7. Kodi ma capacitor ayenera kusankhidwa bwanji kuti achepetse kugwiritsa ntchito mphamvu mu OBC input filter circuit?
A: Mitundu ya YMIN low-ESR (monga, VHU_35V_270μF, ESR ≤8mΩ) ndi yabwino kwambiri kuti ichepetse kutayika kwa ripple. Nthawi yomweyo, mphamvu yotuluka iyenera kukhala ≤20μA kuti ipewe kugwiritsa ntchito mphamvu yoyimirira.
Q:8. Kodi ubwino wa ma capacitor a YMIN okhala ndi capacitance density yapamwamba (monga, VHT_25V_470μF) ndi wotani mu gawo la DCDC output voltage regulation?
A: Kuchuluka kwa mphamvu kumachepetsa mphamvu ya ripple voltage yotuluka ndipo kumachepetsa kufunikira kosefera pambuyo pake. Kapangidwe kakang'ono (10×10.5mm) kamafupikitsa ma PCB ndipo kumachepetsa kutayika kwina komwe kumachitika chifukwa cha kulowetsedwa kwa parasitic.
Q: 9. Kodi magawo a capacitor a YMIN adzasunthika ndikukhudza kugwiritsa ntchito mphamvu pansi pa mikhalidwe yogwedezeka yamagalimoto?
A: Ma capacitor a YMIN amagwiritsa ntchito mphamvu yolimbitsa thupi (monga kapangidwe ka elastic electrode yamkati) kuti apewe kugwedezeka. Kuyesa kukuwonetsa kuti kusintha kwa ESR ndi kutayikira kwa mphamvu pambuyo pa kugwedezeka kuli kochepera 1%, zomwe zimaletsa kuwonongeka kwa magwiridwe antchito chifukwa cha kupsinjika kwa makina.
Q: 10. Kodi zofunikira pakupanga ma capacitor a YMIN ndi ziti panthawi yogwiritsa ntchito soldering ya 260°C?
A: Ndikofunikira kuti ma capacitor akhale ≥5mm kutali ndi zinthu zopangira kutentha (monga ma MOSFET) kuti apewe kutenthedwa kwambiri komwe kumachitika pamalopo. Kapangidwe ka solder koyenera kutentha kamagwiritsidwa ntchito kuchepetsa kupsinjika kwa kutentha panthawi yoyika.
Q: 11. Kodi ma capacitor a YMIN solid-liquid hybrid ndi okwera mtengo kuposa ma capacitor achikhalidwe a electrolytic?
A: Ma capacitor a YMIN amapereka moyo wautali (135°C/4000h) komanso kugwiritsa ntchito mphamvu zochepa (kupulumutsa ndalama zoziziritsira), kuchepetsa ndalama zonse zogwiritsira ntchito chipangizocho ndi zoposa 10%.
Q:12. Kodi YMIN ingapereke magawo osinthidwa (monga ESR yotsika)?
A: Inde. Tikhoza kusintha kapangidwe ka electrode kutengera ma frequency a kasitomala osinthira (monga 100kHz-500kHz) kuti tichepetse ESR kufika pa 5mΩ, kukwaniritsa zofunikira za OBC zomwe zimakhala ndi mphamvu zambiri.
Q:13. Kodi ma capacitor a YMIN olimba ndi amadzimadzi osakanikirana amathandizira nsanja za 800V zamphamvu kwambiri? Kodi mitundu iti yomwe ikulangizidwa ndi iti?
A: Inde. VHT series ili ndi mphamvu yolimba kwambiri ya 450V (monga, VHT_450V_100μF) ndi mphamvu yotuluka ya ≤35μA. Yagwiritsidwa ntchito mu ma module a DC-DC pamagalimoto ambiri a 800V.
Q:14. Kodi ma capacitor a YMIN osakanikirana ndi madzi olimba amawongolera bwanji mphamvu mu ma circuits a PFC?
A: ESR yotsika imachepetsa kutayika kwa ripple yothamanga kwambiri, pomwe mtengo wotsika wa DF (≤1.5%) umaletsa kutayika kwa dielectric, zomwe zimapangitsa kuti PFC igwire bwino ntchito mpaka ≥98.5%.
Q:15. Kodi YMIN imapereka mapangidwe ofotokozera? Kodi ndingapeze bwanji?
A: Laibulale ya kapangidwe ka mphamvu ya OBC/DCDC (kuphatikiza zitsanzo zoyeserera ndi malangizo a kapangidwe ka PCB) ikupezeka patsamba lathu lovomerezeka. Lembetsani akaunti ya injiniya kuti mutsitse.
