Board conditions: FR4, Copper=70μm, four-layer PWB, t=1.6mm ＊In order to select the proper inductor for your circuit design, it should be checked the inductor rated current for heat generation in the worst case. Under normal operational condition, it shall not exceed the maximum operating temperature (150 deg C.) ＊Allowable current of inductor is either saturation current or temperature rise current, whichever is lower. ＊Absolute maximum voltage 40V DC. ＊Take the static electricity measures to prevent deterioration of electric characteristics.
