Cornell Dubilier / Knowles 953B Metallized Polypropylene Film Capacitors

Cornell Dubilier / Knowles 953B Metallized Polypropylene Film Capacitors are designed for reliable filtering and smoothing in uninterruptible power supply (UPS) systems and other AC output filtering applications. CDE 953B features an integrated fused metallization pattern and UL 810 recognition for fail-safe operating at temperatures up to +85°C. The 953B capacitors offer values ranging from 2.5μF to 50μF and voltages at 160VAC, 250VAC, and 275VAC. This CDE series offers -40°C to +85°C performance and meets the requirements of UL 94V-0 for flammability.
