SELF-LEADED SURFACE
MOUNT INDUCTORS
Materials meet UL 94-VO rating
Fits in half inch high boards for use in
laptop and notebook computers
Frequency range of up to 1 MHz
Patented, low profile, self-leaded design
Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C
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 250 KHz and with the
reference ET applied to the inductor.
3. Total loss in the inductor is 380 mWatts 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 I
