Type SEK
105 ºC Radial Leaded Aluminum Electrolytic Capacitors
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.
