Cornell Dubilier Announces Snap-in and Hybrid Lithium-Ion CarbonCap Cylindrical Ultracapacitors
Cornell Dubilier Electronics, Inc. (CDE) announced the release of Type CDLC, CarbonCap Double Layer Capacitors, and Type CDHC hybrid ultracapacitors. Cornell Dubilier’s lineup of large cell cylindrical ultracapacitors spans 1200 to 3000 farads; snap-in style ultracapacitors from 100 to 600 farads and higher energy hybrid capacitors from 220 to 1000 farads.
CDHC Hybrid Capacitors are half ultracapacitor and half lithium ion battery. These hybrid capacitors store more than twice the energy of typical ultracapacitors and have high cycle life capability compared to batteries. Hybrid capacitors have more power than lithium ion batteries, but less energy storage. By comparison, ultracapacitors have a cycle life capability of a million cycles or more, batteries have a cycle life of around 1000 cycles and hybrid capacitors, more than 20,000 cycles. While the ultracapacitors have a usual working voltage range of 1.3 to 2.7V, hybrid capacitors operate from 1.0 to 2.3V. The higher energy of hybrid capacitors makes them especially suitable for use in LED lighting and emergency pulse applications, e.g. operation of electric doors and windows.
Type CDLC CarbonCap Ultracapacitor Cells are available with axial, M12 threaded mounting studs on both ends as well as additional mounting options. The new snap-in units are available in 2 and 4 pin versions and are well suited for wind turbine blade pitch control.
The large ultracapacitors handle back-up and pulse power applications such as grid stabilization. They also excel in transportation applications like automotive subsystems, rail system power and utility vehicles. They provide extended power allowing critical information and functions to remain available during dips, sags, and outages in the main power source. These cells can relieve batteries of burst power functions, thereby reducing costs and maximizing space and energy efficiency. Units with axial cylindrical design enables low ESR and high peak currents with an electrostatic storage capability that can cycle a million charges and discharges without performance degradation.
Type CDLC can work in parallel with batteries for applications that require both a constant power discharge for continual function and a pulse power for peak loads. The CDLC delivers the peak power thus reducing the peak current from the battery and extending battery life and reducing battery size and cost.

Both series are available now with prices starting at $10.00 each.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
