查询词典 copper-bearing

If one square inch of copper is used as a heat dissipator for the TO-252, the J-A drops to approximately 50C/W. The SOT-223 package has a J-A of approximately 125C/W when soldered down to a minimum sized pattern (less than 0.1 square inch) and approximately 70C/W when soldered to a copper area of one square inch.

如果一平方英寸的铜是作为的TO - 252热消使用时，司法机构政务长下降到大约50 / W的的SOT - 223封装具有的司法机构政务长大约125C / W的焊接时下跌不到0.1平方英寸的最小尺寸为1型和大约70 / W型焊接时，一铜一平方英寸面积。
