Screw Terminal
Capacitors

Power Film - DC Link

CDE is the industry’s leading
manufacturer of screw terminal
aluminum electrolytic capacitors
for inverter applications. Use our
online Java applet tool to estimate
capacitor lifetime based on
operating conditions.

CDE offers the most advanced
metallized film technology for long
life and high reliability in DC link
applications. Available in a variety
of package styles, our technology
combines high capacitance and very
high ripple current capability needed
for today’s inverter designs for wind,
solar, fuel cells, UPS systems, medical
power and more.

IGBT Snubber Modules

Type CDHC and CDLC Ultracapacitors

Low inducance snubbers protect
IGBT modules from overvoltage
transients. Choose from three
styles that mount directly to
single and dual IGBT modules for
maximum protection.

CDE’s type CDLC high power
ultracapacitors offer extremely high
capacitance values (Farads) ranging
from 100 to 3000 F. CDE’s type CDHC
snap mount hybrid ultracapacitors
are designed for board mountable
power backup applications. These
hybrid capacitors charge rapidly and
discharge slowly.
