Ukuqina Kwe-ESR Okuphezulu:
Izinga lokushisa eligcwele (-55°C kuya ku-135°C): ≤1.8mΩ ukushintshashintsha (imikhiqizo encintisanayo iyashintshashintsha >4mΩ).
“Inani le-ESR lihlala liphakathi kuka-9 no-11mΩ, liphakeme kune-VHU ngokuguquguquka okuncane.”
Inani Lobunjiniyela: Yehlisa ukulahlekelwa kwesistimu yokulawula ukushisa ngo-15%.
Ukuphumelela kumthamo wamanje we-Ripple:
Ukuqhathanisa Okulinganiselwe: Umthamo wamanje wokuthwala we-VHE udlula izimbangi ngo-30% ngosayizi ofanayo, usekela amamotho anamandla aphezulu (isb., amandla epompo yamanzi e-electronic angakhushulwa abe ngu-300W).
Impumelelo Empilweni Nezinga Lokushisa:
135°C indinganiso yokuhlola vs. 125°C → Ilingana nendawo efanayo engu-125°C:
I-VHE ilinganise impilo: amahora angu-4000
Impilo yokuncintisana: amahora angu-3000 → izikhathi ezingu-1.3 kunezimbangi
Ukuthuthukisa Isakhiwo Semishini:
Ukwehluleka okujwayelekile kwezimbangi: Ukukhathala kwe-solder (izinga lokwehluleka >200W kuzimo zokudlidliza) FIT)
I-VHE: "Ukugcwala okuthuthukisiwe kanye nokumelana nokushaqeka, ukuzivumelanisa nezimo zokuma kokuqala."
Ukuthuthukiswa okulinganiselwe: Umkhawulo wokuhluleka kokudlidliza ukhuphuke ngo-50% (50G → 75G).
Q:17. Iluphi uhla oluthile lokuguquguquka kwe-ESR lwama-VHE capacitor kulo lonke ibanga lokushisa?
