Aluminum Electrolytic Capacitors with Hybrid Electrolyte
Aluminum Electrolytic Capacitors with Hybrid Electrolyte
EP cap is electrolytic capacitors with hybrid cathode electrolyte, which is realized by adding electroconductive polymer to cathode
electrolyte. The structure of hybrid cathode electrolyte keeps its self-healing function as aluminum electrolytic capacitors. And EP cap
can reduce by a large amount ESR and impedance at high frequency 1MHz） compared with aluminum electrolytic capacitor.

Aluminum Electrolytic Capacitors with Hybrid Electrolyte
CV-EX
Series
Surface Mount Type Low ESR at high frequency
CV-EX series are the first electrolytic capacitors with hybrid cathode electrolyte in our
field, which is realized by adding electroconductive polymer to cathode electrolyte.
Structure of hybrid cathode electrolyte keeps their self-healing function as aluminum
electrolytic capacitors.
CV-EX series can reduce by a large amount ESR and impedance at high
frequency(1MHz) as compared with aluminum electrolytic capacitor(our low impedance
series), also they have excellent long load life and temperature characteristics.
