SMT POWER INDUCTORS Toroid Series Ruggedized Ruggedized header with SLED rails for secure board mounting Current Rating: up to 3.8ADC Inductance Range: 9.4µH to 439µH Moisture Sensitivity Level: 1 Part 9 Number Inductance @ Irated (µH) SLED 25 PL8500 PL8501 PL8502 PL8503 PL8504 PL8505 PL8506 PL8507 PL8508 PL8509 9.4 13.3 23 50 75 90 137 200 305 439 Electrical Spe cifications @ 25°C — Operating Temperature - 40 °C to +130 °C 100 Gauss DCR (mΩ) Inductance ET Irated @ 0ADC ET100 (A ) (V-µsec) TYP MAX (µH ±10%) (V-µsec) 3.80 3.20 2.40 1.60 1.30 1.20 1.00 0.82 0.66 0.56 27 40 65 121 181 246 387 585 845 1322 NOTES: 1. The reference inductance at rated DC current is a typical value. 2. Temperature rise is 50°C in typical buck or boost circuits at 250kHz and with the reference ET applied to the inductor. 3. Total loss in the inductor is 380mW for 50°C temperature rise above ambient. 4. To estimate temperature rise in a given application, determine copper and core losses, divide by 380 and multiply by 50. 5. For the copper loss, calculate IDC2 X RN. 6. For core loss, using frequency (f) and operating flux density (B), calculate 6.11 x 10-18 x B2.7 x f2.04.

For flux density (B), calculate ET (V-µsec) for the application, divide by ET100 from the table, and multiply by 100. 8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table by IDC of the application. 9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PL8500 becomes PL8500T).
