Click here to access the loss calculator tool ign Criteria IHLP inductors have a recommended maximum component temperature of 125 C Subtracting the ambient temperature will give us the maximum allowed temperature rise for the part If this number should exceed 40 C it is recommended that 40 C be used for the allowed temperature rise Core losses should be limited to lt 1 3 of the total losses to mitigate any aging effects associated with the powdered iron in the core at temperatures exceeding 125 C The recommended range for the ripple current is 30 to 5096 of inductor current This is based on a trade off of inductor size and cost versus output capacitor size and cost The maximum peak current should be kept below the lat value of the selected inductor although it can be exceeded with caution due to the soft saturation characteristics of the powdered iron core material The calculators are based on operation in the continuous conduction mode only information determined in the discontinuous conduction mode should be considered suspect and in need of verification by the user Products Company Press Investors Contacts Acquired Manufacturers Privacy amp Legal Site Map Your Account CONTACT US Sales Technical Questions BUY NOW Check Distributor Stock mm Build Vishay into your Design English 2 Submit QUALITY AND APPLICATIONS COMPANY INFO ENVIRONMENTAL Products
