Cornell Dubilier Introduces Protected Metalized Polypropylene Film Capacitors Target UPS Systems and AC Filtering Applications
Design incorporates fuse protection, UL 810 Approved for Fail-Safe Operation
Liberty, SC (June 2018) — Cornell Dubilier announces the availability of its newest 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.
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 builtin 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.
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.
Samples of 951C and 953B capacitors are available in 4-6 weeks, production in 8-10 weeks. For inquiries, contact: Mike Rapoza, Product Marketing Manager, firstname.lastname@example.org, (508) 996-8561 ext. 1110. For more information on these series visit: http://www.cde.com/news/2018/6/953b
