Conduction-Cooled Capacitors Handle High Currents and Voltages
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 1,200A RMS and 1,100Vac.
Applications include: induction heating, resonant power supplies, RF amplifiers, medical imaging systems, welding equipment and electric vehicle charging stations.
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 2SM6 direct-mount option uses a through-hole design that is compatible with many current application configurations. Available in the HC1, HC2, HC3A and HC3B Series, the new mounting configuration provides the highest level of heat transfer and connectivity. It also eliminates the need for intermediate mounting hardware, allowing direct mounting to bus bars.
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, special construction techniques are utilized to help minimize the potential for corona breakdown.
Illinois Capacitor's Conduction Cooled Capacitors incorporate self-healing Polypropylene film construction. They are Halogen free, ROHS compliant and meet UL94V0 as flame retardant.
HC and LC Series Conduction Cooled Capacitors are available for immediate delivery at DigiKey and Mouser.
