Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application All data presented are preliminary and subject to change (1) DC current (A) that will cause an approximate T of 40 C (2) DC current (A) that will cause L to drop approximately 30 % 0 DIMENSIONS in inches millimeters 30.5 max. 2 3 2 3.0 3 12 C B 10.25 A 43 1 4 1 15.75 4 4 x 3.4 0.3 7.5 24.5 max.
