Cornell Dubilier ultra-flat aluminum electrolytic capacitor saves board space

New Yorker Electronics has announced the distribution of a new ultra-low-profile (ULP) aluminum electrolytic capacitor from Cornell Dubilier Electronics (CDE) that is designed for bulk capacitance and the lowest board profiles.

Now, circuit designers can use a single component, saving space, weight and cost while improving dependability. Energy density of over 0.4 J/cc enables the use of a single component instead of an entire array of surface mount technology capacitors. This improves circuit reliability while achieving high capacitance on the board.

Due to its light weight, the ULP is ideal for use in portable devices and is well suited for a wide range of applications where height profile, board space, weight and reliability are critical design factors. The ULP is offered in package heights of 2.2 mm and 3.2 mm. Capacitance values range from 500 µF to 24,000 µF. Working voltages range from 4 to 63 working volts DC, with an operating life of 3,000 hours at 85° C. Unlike solid tantalum capacitors, type ULP capacitors do not require voltage derating.

Housed in a highly durable nickel-silver case, the low-profile capacitor is rated at 10 g for vibration. As thin as 2.2 mm, the ULP series capacitors are easy to design-in. With flat ribbon-lead-style terminations, it is even possible to mount the device off board, providing added design flexibility to maximize available space.

Developed by Cornell Dubilier and distributed worldwide by New Yorker Electronics, the ULP breaks away from the cylindrical designs usually associated with aluminum electrolytic capacitors. The design is an outgrowth of the company’s over 20 years of experience in the manufacturing of aerospace-grade flat capacitors.
