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 Isolation voltage, coil to core: 350 V , 60 s, 5 mA max., DC (1) DC current (A) that will cause an approximate T of 40 C (2) DC current (A) that will cause L to drop approximately 20 % 0 (3) DC current (A) that will cause L to drop approximately 30 % 0 DIMENSIONS in inches (millimeters) (25.53 0.50) 1.005 0.020 A (20.73 0.75) (21.75 1.00) 0.816 0.030 B 0.856 0.039 (2.56 0.50) (6.00 1.00) (3.66 0.50) 0.101 0.020 0.236 0.039 0.144 0.020 (19.06 0.50) (4.00 0.40) 0.750 0.020 0.158 0.016 Revision: 12-Apr-2019 Document Number: 34522 1 For technical questions, contact: magnetics vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
