The value is specified under the condition that either color is lightened separately. When the both diodes are lightened simultaneously,
the power dissipation of each diode should be less than the half of the value specified in this table.
*1 Duty ratio=1/10, Pulse width=0.1ms
*2 For 3s or less at the temperature of hand soldering.

便携式医疗设备的特殊性决定了它们应该是对用户友好的、必须工作在无菌环境下，并且空间占用小、耗能低。 同时，便携式医疗设备还需要足够的计算能力以便处理医疗数据，能够连接到无线或有线接口以便记录和发送数据。从设计人员的角度考虑，上述需求需要低功耗的单片机（MCU）和数字信号控制器（Digital Signal Controller，DSC）。 正是有了嵌入式处理器，设计人员才有可能设...[详细]
