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 • Rated operating voltage (across inductor) = 50 V (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) In this configuration, current flowing opposite directions through coils cancels and the 1.5 μH inductance is very stable with varying current. Observe the heat rating current to avoid excessive temperature rise in this configuration • PATENT(S): www.vishay.com/patents • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS • SEPIC converters • DC/DC converters • Common mode applications • LED lighting DIMENSIONS in inches [millimeters] Side View Top View 4 0.400 ± 0.005 [10.16 ± 0.127] 1 4 1 0.080 ± 0.005 [2.03 ± 0.127] 3 0.110 ± 0.005 [2.79 ± 0.127] 0.220 [5.588] 4 3 1 2 2 0.158 [4.0] Max.
