The rated current as listed is either 85% of the saturation current orthe heating current, In order to determine the approximate total losses (or temperature rise) for a given depending on which value is lower. application, the total copper and core losses should be taken into account. For approxi2. The saturation current is the current which causes the inductance todrop by 15% at the mate value of core losses, in a given application, use the core loss graph on page 24. stated ambient temperatures (25°C and 100°C). This current is determined by placing 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part the component in the specified ambient environment and applying a short duration number (i.e. PL2059 becomes PL2059T). Pulse complies to industry standard tape and pulse current (to eliminate self-heating effects) to the component. reel specification EIA481. 3. The heating current is the DC current which causes the temperature of the part to in6. Meets solderability test per IPC/EIA J-STD-002B using flux type ORL0. crease by approximately 45°C. This current is determined by mounting the component 7. The temperature of the component (ambient plus temperature rise) must be within on a PCB with .25” wide, 2 oz. equivalent copper traces, and applying the current to the the stated operating temperature range. device for 30 minutes with no forced air cooling. 4. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor which may neccessitate derating the current in order to limit the temperature rise of the component.
