Cornell Dubilier introduces metalized polypropylene film capacitors for UPS, AC power supplies, and general AC filtering applications
The 951C and 953B series offer strong performance for filtering in applications where high ripple currents are encountered and benign end-of-life failure mode is essential. The 951C has a cylindrical body with axial leads, while the 953B has a rugged radial box form factor.
951C & 953B Metallized Polypropylene Film Capacitors
Both capacitors offer a fused, segmented metallization pattern, providing significant circuit protection. UL 810 approval assures fail-safe operation under fault conditions. The metallization pattern is deposited on a low-loss, high-grade polypropylene dielectric. The built-in fuse-links limit capacitance loss to a small segment within the capacitor. This is in contrast to the larger areas of uncontrolled capacitance loss observed with non-segmented types. This capability is not usually available for board-mounted capacitors.
Specification
The axial-leaded 951C Series is offered in values ranging from 0.825 to 40 μF, while the 953B spans 2.5 to 50 μF. Voltage ratings in both series are available at 160, 250 and 275 Vac. Both types offer -40 to +85°C performance and meet the requirements of UL 94V-0 for flammability.
With a 10,000-hour service-life expectancy without derating, series 951C and 953B capacitors will excel at providing reliable filtering and smoothing for today's demanding applications in UPS systems, AC power supplies and more.
