Introducing Cornell Dubilier's PPC series

Cornell Dubilier's 1mm thin polymer aluminium electrolytics provide high ripple current and capacitance in custom values and shapes

The new PPC Series of ultra-thin polymer aluminium electrolytic capacitors from Cornell Dubilier represents a totally new capacitor form factor. Designed specifically for applications requiring high ripple current and the thinnest possible profiles, the PPC series opens up new product design options. In addition to being just 1mm thin, the PPC series use versatile packaging technology that makes it possible for capacitors to be formed into custom shapes and sizes to accommodate available space.

“A single PPC capacitor offers capacitance and ripple current equivalent to dozens of SMT capacitors or a bulky cylindrical device,” Mario DiPietro, Product Manager at Cornell Dubilier.

Cornell Dubilier has demonstrated that a single PPC capacitor is equivalent to a parallel bank of 50 or more polymer tantalum capacitors whilst occupying one fourth the height. Also, circuit reliability is improved by using a single component versus an entire array of SMT capacitors.

Custom values are available within a capacitance range of 8,000 µF to 20,000 µF, with working voltages ranging from 6.3 to 24 WVDC. Cornell Dubilier plans to extend the series to higher operating voltages later in 2020. Operating life is 2,000 hours @ 125° C.   

The PPC series is rated for 10g peak for vibration and withstands shocks up to 100g’s (conforming the range to 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 tape, to ensure that the entire capacitor surface is kept rigid.  

Developed by Cornell Dubilier, the PPC is the latest leading-edge capacitor development by the company. These designs have been responsive to market demands for capacitors that provide higher performance while breaking away from traditional cylindrical form factors.
