M178.B (3/13) pulseelectronics.com SMT Power Inductor Military/Aerospace Grade Height: 7.1mm Max Footprint: 14.6mm x 12.6mm Max Current Rating: up to 15A MSL: 1 Frequency Range: 50kHz to 500kHz Finish is Tin/Lead (Sn63/Pb37) Storage Temperature: -55ºC to +130ºC Max Reflow Temperature: 235ºC Electrical Specifications @ 25°C — Operating Temperature -40°C to 130°C Part Number Inductance @ Irated (µH ±15%) Irated (ADC) DCR (mΩ) Inductance @ 0 ADC (µH ±15%) Saturation Current Heating Current (A)TYP MAX 25°C 100°C 2-TURN (LOW-LOSS) SERIES PL2059 0.85 39 .38 .48 0.91 46 37 73 N otes: 1. The rated current as listed is either 85% of the saturation current orthe heating current, depending on which value is lower. 2. The saturation current is the current which causes the inductance todrop by 15% at the stated ambient temperatures (25°C and 100°C). This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 3. The heating current is the DC current which causes the temperature of the part to in- crease by approximately 45°C. This current is determined by mounting the component on a PCB with .25” wide, 2 oz. equivalent copper traces, and applying the current to the 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. In order to determine the approximate total losses (or temperature rise) for a given application, the total copper and core losses should be taken into account. For approxi- mate value of core losses, in a given application, use the core loss graph on page 24. 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PL2059 becomes PL2059T). Pulse complies to industry standard tape and reel specification EIA481. 6. Meets solderability test per IPC/EIA J-STD-002B using flux type ORL0. 7. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
