1. Actual temperature of the component during system operation (ambient plus tempera- 3.
ture rise) must be within the standard operating range.
2. The saturation current is the current at which the initial inductance drops approximately
30% at the stated ambient temperature. This current is determined by placing the com-
ponent in the specified ambient environment and applying a short duration pulse cur- 4.
rent (to eliminate self-heating effect) to the component.
The rated current is the DC current required to raise the component temperature by
approximately 40½C. Take note that the components’ performanc varies depending on the
system condition. It is suggested that the component be tested at the system level, to
verify the temperature rise of the component during system operation.
The part temperature (ambient+temp rise) should not exceed 155½C under worst case
operating conditions. Circuit design, PCB trace size and thickness, airflow and other cool-
ing provisions all affect the part temperature. Part temperature should be verified in the
end application.

xi 在国际测试大会上，英特尔公司副总裁兼副总经理Gadi Singer在题为“应对频谱纳米技术和千兆复杂性的挑战”的演讲中指出，从1940年以来，每立方英尺MIPS或每磅MIPS数每10年就增加100倍。虽然在平滑的曲线上一直是以指数规律变化，但是，在那个时期仍然有许多不连续性和变形点。 “目前，四个不同的趋势正延伸在所有方向中的曲线，”Singer说道。首先，IC复杂性和多样性...[详细]
