The UTOR series now offers higher capacitance and ripple current per case size. The upgrade allows

the inverter designer to significantly reduce the size, weight, and cost of the capacitor bank. Its

patented toroidal geometry is ideal for cooling by either forced air or by heat-sink with the use

of a new mounting kit option. The heat-sink kit option provides optimum thermal transfer while

maintaining electrical isolation. These capacitors have an endurance rating of 5,000 hours at

105 C or 20,000 hours at

85 C with the rated ripple current applied. The UTOR series represents

the optimum cost per amp of ripple current for a screw terminal mounted electrolytic capacitor.
