Re: Core i7 aneb Intel Nehalem infa a testy apod
To je udávaná životnost při provozní teplotě při 105 °C.Původně odeslal Dix
Nevite nekdo co chteji rict "5000 hours" Fujitsu capacitors? Predstava ze mi deska vydrzi 208 dni a pak umrou kondiky je dost divna ne
Trošku jsem to nakousl tady a tady.
Jde vlastně o násobky základní teploty (105 °C) a jsou uvedené v datasheetu. Výrobce garantuje, že parametry kondenzátoru jako je ESL, ESR a kapacita během této doby (hodiny v provozu) nepřekročí mimo udávané specifikace. Poté je povolená odchylka obvykle o 150 %.105°C - 4 000h
95°C - 8 000h
85°C - 16 000h
75°C - 32 000h
65°C - 64 000h
A když už jsme u té skryté reklamy, tak nesmím zapomenout na svoji brněnskou domovinu jménem Svět hardware a Computer Press, kde tyto údaje čas od času popisuji v recenzích. S kvalitní recenzí na EHW se počítalo, CDRko bylo příjemné překvapení.
A abych nebyl úplně OT, tady je zlomek surových dat, které jsem ještě neměl čas zpracovat.
