Kemet - T52B157M006ATE035
【产品特性】Select a bulk capacitance of approximately 1000 μF in parallel to the System Power/Power Amplifier. Due to the height limit, especially on the PC Card slot, the capacitance solution must be ≤ 2 mm. The following chart outlines possible design options:
• kemet Polymer series(Low ESR) T520V337M006ATE025 ,7343-1.9mm/330uF/6.3V/ESR025.
• kemet Polymer series(Low ESR) T52B157M006ATE035 ,3528-1.9mm/150uF/6.3V/ESR035.
• kemet Polymer series(Low ESR) T52B227M006ATE045 ,3528-1.9mm/220uF/6.3V/ESR045
• Wireless modems for broadband connection with 2G+ networks
• Protocol support: GSM/GPRS/EDGE, HSDPA, HSDPA+, HSUPA, TD-SCDMA, WCDMA
• Form Factor: USB, PC Card, PCI Express I/O interfaces such as notebook computer USB and PC Card ports have the following clearly defined power limitations:
• USB 2.0: 0.5A @ 5V
• PCMCIA: 1A @ 3.3V
However, the 578 μs transmission burst within the GSM-TDM protocol requires a peak current between 1.5A and 2A.

【文字介绍】The T520 Series KO-CAP Low ESR Polymer captures the best features of multilayer ceramic (low ESR, high frequency capacitance retention), aluminum electrolytic (higher capacitance, benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, extremely long life).
The T520 can reduce component counts, eliminate through- hole assembly by replacing cumbersome leaded aluminum capacitors, and offer a cost-effective and space-saving solution.
