Type SEK 105 ºC Radial Leaded Aluminum Electrolytic Capacitors

Type SEK is a radial leaded aluminum electrolytic ca-

Long Life, Aluminum Electrolytic

pacitor with a +105 º C, long life rating. The volumetic

efﬁcient high CV product of the SEK makes it ideal for

high density packaging in general purpose, coupling,

decoupling, bypass and ﬁltering circuit applications.
