Parts are soldered by reflow on four-layer PWB (1. mm FR) and measured at room temperature. See also ( 5) ( 3) DC current which causes temperature rise of K. Parts are soldered by reflow on multilayer PWB with high heat dissipation performance. Note: Heat radiation constant are approx. 3 K/W measured on...8 mm case size. See also ( 5) ( ) Saturation rated current : DC current which causes L() drop 3 %. ( 5) Within a suitable application, the part s temperature depends on circuit design and certain heat dissipation conditions. This should be double checked in a worst case operation mode. In normal case, the max.standard operating temperature of +15 C should not be exceeded. For higher operating temperature conditions, please contact Panasonic representative in your area.
