Electrical specifications at 25ºC. 2. Tested at 100kHz. 3. Operating temperature range: -40ºC to +130ºC. Operating temperature is a combination of ambient temperature plus temperature rise. 4. Meets UL 94V-0. 5. Specifications shown are for an inductor with a 55ºC temperature rise. The core loss is 10% of the copper loss when operating at 500kHz. 6. Please remember it is much easier to remove heat from a copper-loss dominated design than from a core-loss dominated design. 45 (03/08) ISL & ISH-1 ISL & ISH Series SMT Power Inductor Mechanical - ISL37 Packaging: Reel Diameter=13”, Reel Width=32mm, Pieces/reel=300 pieces Recommended PCB Layout ��������� Schematic �������� �������������� ���������� �������� ��������� �������� � �������������� � �������������� units: mm Mechanical - ISH37 Packaging: Reel Diameter=13”, Reel Width=32mm, Pieces/reel=250 pieces Recommended PCB Layout ��������� Schematic �������� �������������� ��������� ��� ����� �������� ���������� �������� �������������� � � �������������� units: mm Mechanical - ISL44 Packaging: Reel Diameter=13”, Reel Width=32mm, Pieces/reel=250 pieces Recommended PCB Layout Schematic �������� ��������� �������������� ��������� �������� ���������� �������� �������������� � � �������������� units: mm Specifications subject to change without notice. 800.729.2099 tel www.icecomponents.com 46 (03/08) ISL & ISH-1
