Cornell Dubilier PPC Series 1mm-Thin Polymer Aluminum Electrolytics

Provides High Ripple Current and Capacitance
Thinner than a dime, available in custom values and shapes.

The new PPC Series of ultra-thin polymer aluminum 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, type PPC opens up 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.

“A single PPC capacitor offers the capacitance and ripple current equivalent to dozens of SMT capacitors or a bulky cylindrical device,” said Mario DiPietro, Product Manager at Cornell Dubilier. As an example, a single PPC capacitor is equivalent to a parallel bank of 50 or more polymer tantalum capacitors and occupies one-fourth of 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 8,000µF to 20,000µF, with working voltages ranging from 6.3 to 24 WVDC. Operating life is 2,000 hours @ 125° C.

The PPC is rated for 10g 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. Mounts with 3M double-sided VHB tapeTM, to ensure that the entire capacitor surface is kept rigid.

A list of ideal applications for the product.

Applications requiring high ripple current, high capacitance, low-profile designs.

These could include:

• Compact DC/DC Converters
• Power Supplies
• Solar power arrays
• IoT systems

Description of the product’s purpose.
A new capacitor form factor that provides bulk storage, designed specifically for applications requiring low ESR, high-ripple current and the thinnest-possible profiles.

What problem does it solve?
Type PPC opens-up 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. It allows designers to make lower profile, more reliable power products.

How does it improve on older products/what it evolved from?
Older polymer aluminum products are much bulkier in volume and weight. It also has excellent mechanical specifications. The PPC is rated for 10g peak for vibration and withstands shocks up to 100 g’s (MIL-STD-202, Method 213, Condition I).

How is it different from competitive products? What advantages does it have?
To the best of our knowledge, there are no other flat polymer aluminum capacitors.
