3.CHARACTERISTICS
(1). All test data is based on 25℃ ambient.
(2). DC current(A)that will cause an approximate
△T40℃
(3). DC current(A)that will cause L0 to drop approximately 10%Typ
(4). Operating temperature range: -55℃~+125℃
(5).The part temperature (ambient + temp rise)should not exceed 125℃ under worst case operating
conditions. circuit design, component.PWB trace size and thickness,airflow and other cooling
provision all affect the part temperature. Part temperature should be verified in the den application
