New Yorker Electronics has announced the release of a new ultra-thin polymer electrolytic capacitor that represents a totally new capacitor form factor. The Cornell Dubilier Electronics’ new PPC Series, designed specifically for applications requiring high ripple current and the thinnest profile possibilities, opens up entirely new product design options. In addition to being just 1 mm thin, the PPC uses versatile packaging technology that makes it possible for capacitors to be formed into custom shapes and sizes to accommodate available space.
Rated for 125°C, PPC combines the advantages of aluminum electrolytic and aluminum polymer technology. These capacitors have the ultralow ESR characteristics of conductive aluminum polymer capacitors in a 1mm thin package. With high capacitance and high ripple current per volume, applications for 125°C polymer capacitors include DC/DC converters, tablets, telecommunications, thin displays, and variety of industrial power conversion.
A single PPC capacitor can handle ripple currents equivalent to dozens of SMT capacitors or a bulky cylindrical device. In fact, CDE has stated that a single PPC capacitor is equivalent to a parallel bank of 50 or more polymer tantalum capacitors – at one fourth the height. Using a single unit means PPC capacitor solutions are lighter in weight and can improve overall circuit reliability.

Data Sheets:
Custom values are available within a capacitance range of 8,000µF to 20,000µF, with working voltages ranging from 6.3 to 24 WVDC. Cornell Dubilier plans to extend the series to higher operating voltages later in the year. Operating life is 2,000 hours @ 125°C.
The PPC is rated for 10 g peak for vibration and withstands shocks up to 100 g’s (MIL-STD-202, Method 213, Condition I). With flat tin-plated copper terminations, it is possible to mount the device off-board or directly to a PCB. Mounting is by means of 3M double-sided VHB tapeTM, to ensure that the entire capacitor surface is kept rigid.
