SMT POWER INDUCTORS
Shielded Toroid Series - Ros1/Ros2 Series
Notes:
1. Temperature rise is 55°C in typical buck or boost circuits with the rated I
DC
current and reference ET applied to the inductor.
2. Total loss in the inductor is 80 mW (ROS 1) and 280 mW (ROS 2) for 55°C
temperature rise above ambient.
3. To estimate temperature rise in a given application, you must determine the
total losses (copper losses + core losses) and apply the following formula:
Temp Rise (C) = (Total Losses (mW))
.833
* KO (from table)
4. To determine copper losses, calculate:
Copper Loss (mW) = I
DC2
x DCR
5. For core loss in mWatts, using frequency f (in Hz) and operating
flux density B (in Gauss), calculate:
Core Loss (mW) = k2 * f
1.26
* B
2.11
6. For flux density (B), calculate ET (V-µsec) for the application,
and multiply by ET
10
factor from the table.
