Illinois Capacitor expands its HC and LC series of conduction cooled capacitors used in resonant power circuitry with very high current demands

By Heather Hamilton, contributing writer

Illinois Capacitor recently expanded its lineup of HC
and LC Series Conduction Cooled Capacitors
, which include new direct
mounting options for the HC Series. The devices target high current demands
required by resonant power circuitry. The new line is rated up to 1,200 amps
RMS and 1,100 VAC.
 

The LC Series capacitors enable safe handling
of current and voltage in resonant power circuits, thanks to their flat copper
plates. The HC capacitor’s direct-mount options utilize a through-hole design,
compatible with a variety of current application configurations and is
available for four HC types. The direct-mounting configuration provides a high
level of connectivity as well as heat transfer, while eliminating the need for
intermediate mounting hardware. 

Devices are compatible with resonant circuits
from 9 kHz to 1 MHz, depending on capacitance, with standard capacitance values
ranging from 0.05 µF
to 37µF. The operating temperature range is-40°C to 85°C.  Both series use impregnated dielectrics to
prevent corona problems within the capacitor, which can be a problem in high-power
RF applications.

These
capacitors use self-healing polypropylene film construction. They are also
halogen free and ROHS compliant and meet UL94V0.

Applications
include induction heating, RF amplifiers, welding equipment and electric
vehicle charging stations, resonate power supplies, and medical imaging
systems. Both HC and LC Series capacitors are available through Digi-Key and
Mouser.
