Q: 16.Ndezvipi zvakanakira kuenzanisa kweVHE capacitors zvichienzaniswa nevakwikwidzi (zvakadai sePanasonic uye Chemi-con)?
Superior ESR Kugadzikana:
Tembiricha yakazara (-55 ° C kusvika 135 ° C): ≤1.8mΩ kushanduka (kukwikwidza zvigadzirwa zvinoshanduka> 4mΩ).
"ESR kukosha inoramba iri pakati pe9 ne11mΩ, yepamusoro kune VHU ine kuderera kudiki."
Kukosha kweUinjiniya: Inoderedza kurasikirwa kwehurongwa hwekupisa ne15%.
Kubudirira muRipple Current Capacity:
Measured Comparison: VHE yazvino inotakura simba inodarika vakwikwidzi ne30% yehukuru hwakafanana, inotsigira epamusoro-simba mota (semuenzaniso, yemagetsi pombi yemvura simba inogona kuwedzerwa kusvika 300W).
Kubudirira muhupenyu uye Tembiricha:
135°C chiyero chebvunzo maringe nemukwikwidzi's 125°C → Yakaenzana neyakafanana 125°C nharaunda:
VHE yakayerwa hupenyu: 4000 maawa
Hupenyu hwemakwikwi: maawa 3000 → 1.3 nguva yevakwikwidzi
Mechanical Structure Optimization:
Zvakajairwa mukwikwidzi kutadza: Solder kuneta (kutadza chiyero> 200W mumamiriro ekudengenyeka) FIT)
VHE: "Yakawedzera kuremerwa uye kuramba kuvhunduka, kuchinjira kumamiriro ekutanga-kumira."
Kuvandudzwa kwakayerwa: Vibration kutadza chikumbaridzo chakawedzera ne50% (50G → 75G).
Q:17. Chii chinonzi ESR fluctuation range yeVHE capacitors pamusoro pese tembiricha renji?
A: Inochengetedza 9-11mΩ kubva -55 ° C kusvika 135 ° C, ine kuchinja ≤22% pane 60 ° C tembiricha kusiyana, izvo zviri nani kupfuura 35% + kuchinja kweVHU capacitors.
Q:18. Ko kutanga kushanda kweVHE capacitors kunoderedza kutonhora kwakadzika (-55 ° C)?
A: Chimiro chehybrid chinovimbisa huwandu hwekuchengetedza huwandu hwe> 85% pa -55 ° C (electrolyte + polymer synergy), uye ESR inoramba iri ≤11mΩ.
Q:19. Chii chinonzi voltage kuwedzera kushivirira kweVHE capacitors?
A: VHE capacitors nekuwedzera kushivirira: Vanotsigira 1.3 times the rated voltage for 100ms (semuenzaniso, 35V model inogona kumira 45.5V transients).
Mubvunzo: 20. VHE capacitors inoenderana nemamiriro ekunze (RoHS / REACH)?
A: YMIN VHE capacitors inosangana neRoHS 2.0 uye REACH SVHC 223 zvinodiwa (yakakosha mitemo yemotokari).
