Hybrid polymer-aluminium electrolytics give designers the best of both worlds
Cornell Dubilier Electronics (CDE) has released the type HZC hybrid
polymer-aluminium electrolytic capacitors. Rated for 125C, type HZC combines
the advantages of aluminium electrolytic and aluminium polymer technology.
The hybrid capacitors have the ultra-low ESR characteristics of conductive
aluminium polymer capacitors packaged in a V-chip, SMT case with high
capacitance and voltage ratings that were previously available only in
aluminium electrolytic technology. Applications for type 125C hybrid
capacitors include a variety of industrial power conversion, lighting
control and automotive applications.
Capacitance values range from 10µF to 330µF at voltage ratings from 25VDC to
63VDC and ripple current values exceeding 2000mA for some of the larger chip
sizes. When operated at their rated temperature of 125C and rated voltage at
full ripple current rating, type HZC capacitors have a load life exceeding
“The hybrid HZC series gives the design engineer the best of both worlds,”
said Bill Haddad, product manager. “Hybrid capacitors utilize a combination
of liquid electrolyte and solid polymer giving them high ripple current
capability at high capacitance and voltage ratings. They allow the design
engineer to use fewer capacitors to meet the capacitance and ripple current
demands for their power conversion application."
