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 PATENT(S): www.vishay.com/patents This Vishay product is protected by one or more United States and international patents.
