PCMCIA and Compact Flash
Wireless devices capable of delivering 2.5G, 3G, 802.16 and 4G communication services face a critical
shortage of power. Pulse transmissions generally exceed the power limitations of wireless modem devices
such as PCMCIA, CompactFlash®, USB and mini PCI cards, leading manufacturers to seek components that
consume less power and even add batteries to the products
CAP-XX supercapacitors actually enable battery elimination while providing the high current pulses needed for
wireless transmission. These small, thin devices permit low temperature operation and reduce EMI noise
to improve transmission reliability and signal quality.
