Solutions

With wireless technology enabling hundreds of consumer and commercial devices, the world has become power-pulse hungry. Mobile phones, wireless modems, digital cameras, and PDAs require short bursts of power for data transmissions or peak-power functions — power that batteries or power rails limited to a maximum current such as PCMCIA or compact flash can't supply.

Supercapacitors bridge the gap between the average level of power provided and the pulse power needed in operation. Used alone, with a power supply, or together with batteries, supercapacitors create advanced power solutions that enable the latest technologies. Discover how CAP-XX products add value in wireless, consumer, and commercial devices.

 

Advantages and Uses

In addition to providing pulse power, CAP-XX supercapacitors provide the following features and advantages:

• Extends battery run time by minimizing the voltage droop caused by a high-current load
• Provides the high-current pulses required by the load and smoothes the fluctuating power required from the low current source
• Minimizes electrical and acoustic noise generated by current pulses in ruggedized PDAs and other systems by smoothing the fluctuating power required from the battery
• Permits low-temperature operation in ruggedized PDA and LiTC applications and high-temperature operation in PCMCIA and other modems
• Provides technical benefit in small volume/mass, particularly in compact flash and PCMCIA modems in which height and footprint are severely limited. Also enables thinner, smaller industrial design for PDAs, mobile phones, and other consumer applications
• Meets environmental standards for disposal and hazardous operation, which is essential for wireless modems, converged handhelds, the LiTC market, and DSCs
