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.

Ripple Multipliers for Voltage and Temperature:
For capacitors whose capacitance value exceeds 1000 µF,
the value of DF (%) is increased 2% for every additional
1000 µF.
