5 DL-/ D LINK FILM APAITORS Life Expectancy Steps t calculate Htspt Lcate the capacitr and the ESR frm the electrical specificatins Dissipated heat = ( Irms x ESR ) Get the value frm table 1 fr Rth ( /watt) alculate internal temperature rise = ( Irms x ESR ) x Rth ( /watt) Htspt temperature f capacitr = T Ambient + ( Irms x ESR ) x Rth ( /watt) Lk at the graph belw t get the expected life Ensure that the vltage and current specificatin are nt exceeded an size D x H x Rth /Watt. Example: If MFD/ VD is being used at Arms in a Ambient; then ESR frm the value electrical specificatin table =. O and the case size is Dia mm The dissipated wattage = x. O = 1. watts rise = 1. x /Watt = 1. The htspt cre temperature inside the capacitr = (Ambient) + 1. (Rise) =. say Frm the graph belw: If the capacitr is being used at % f Vrdc then the expected life will be apprx, hurs Htspt temperature Vs expected life with respect t % Vrdc Expected Life (Hurs).Vrdc.Vrdc Vrdc 1.1rdc 1.Vrdc O atalgue N.
