Long Life, Aluminum Electrolytic

Type SEK is a radial leaded aluminum electrolytic ca-

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.
