An Expanded Line of Conduction Cooled Capacitors



Illinois Capacitor has expanded their lineup of their HC and LC Series Conduction Cooled Capacitors to include new direct mounting options on the HC Series.  These devices are a fit for resonant power circuitry having very high current demands.  With the rugged appearance of mechanical components, they have ratings of up to 1,200 amps RMS and 1,100 VAC.   The LC Series of capacitors have flat copper plates to allow safe handling the current and voltage in resonant power circuits.  The HC Series are compact rectangular block types.

The new direct-mount option uses a through-hole design that is compatible with many current application configurations.    Available on four HC types, the new mounting configuration provides the highest level of heat transfer and connectivity.  It also eliminates the need to intermediate mounting hardware.

Depending on the capacitance, devices are compatible with resonant circuits ranging from 9 kHz to 1 MHz.  Standard capacitance values range from 0.05 µF to 37µF.  Operating temperature
is -40°C to +85°C.  In high-power RF applications, corona can be a problem within a capacitor.  As a defense against this, the dielectrics used in both series are impregnated.

Applications include: induction heating, resonant power supplies, RF amplifiers, medical imaging systems, welding equipment and electric vehicle charging stations.

Illinois Capacitor’s Conduction Cooled Capacitors incorporate self-healing Polypropylene film construction.  They are Halogen free, ROHS compliant and meet UL94V0 as flame retardant.
