PCMCIA and Compact Flash

sol-pg_w1Wireless 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.
