Mubvunzo:16. Ndezvipi zvakanakira zveVHE capacitors kana tichienzanisa nevanokwikwidza navo (vakadai sePanasonic neChemi-con)?
Kugadzikana kweESR kwepamusoro:
Tembiricha yakakwana (-55°C kusvika 135°C): ≤1.8mΩ kuchinja-chinja (zvigadzirwa zvinokwikwidzana zvinochinja-chinja >4mΩ).
"Kukosha kweESR kunoramba kuri pakati pe9 ne11mΩ, kuri nani pane VHU nekuchinja-chinja kushoma."
Kukosha kweUinjiniya: Kunoderedza kurasikirwa kwehurongwa hwekutarisira kupisa ne15%.
Kubudirira muRipple Current Capacity:
Kuenzanisa Kwakayerwa: Kugona kwekutakura kweVHE pari zvino kunopfuura makwikwi ne30% pahukuru hwakafanana, zvichitsigira mota dzine simba guru (semuenzaniso, simba repombi yemvura yemagetsi rinogona kuwedzerwa kusvika ku300W).
Kubudirira Muhupenyu Nekupisa:
135°C bvunzo yemuyedzo uchienzaniswa ne125°C yemukwikwidzi → Yakaenzana nenzvimbo imwechete ye125°C:
Hupenyu hweVHE hwakatarwa: maawa 4000
Hupenyu hwemakwikwi: maawa 3000 → ka1.3 kupfuura evakwikwidzi
Kugadzirisa Magadzirirwo Emakanika:
Kukundikana kwakajairika kwemukwikwidzi: Kuneta kweSolder (chiyero chekukundikana >200W muzviitiko zvekudedera) FIT)
VHE: "Kuwedzerwa kwesimba rekudzivirira kuvhunduka uye kudzongonyedzwa, kuchichinja kuti zvienderane nemamiriro ezvinhu anowanzo tanga-kumira."
Kuvandudzwa kwakayerwa: Muganho wekukundikana kwekuzununguka wakawedzera ne50% (50G → 75G).
