Cornell Dubilier's 935C series capacitors are specifically engineered for demanding high-frequency filtering and high-current applications, particularly in switching power supplies operating within the 20-100 kHz range. Their low equivalent series resistance (ESR), high current capacity, and high capacitance provide a significant advantage over general-purpose capacitors. These capacitors are UL recognized for construction only and are designed to withstand high voltage and temperature conditions. They are commonly used in power conversion systems, motor drives, and other applications requiring robust and reliable capacitor performance.
