SMT POWER INDUCTORS

Toroid - Bobcat Series

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.

6. For core loss (mW), using frequency (f in Hertz) and operating flux density

7. For flux density (B in Gauss), calculate ET (V-µsec) for the application, divide

9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part

number (i.e. P0144NL becomes P0144NLT). Pulse complies to industry standard

tape and reel specification EIA481.

10. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts

are not necessarily RoHS compliant, but are electrically and mechanically equivalent

to NL versions. If a part number does not have the "NL" suffix, but an RoHS

compliant version is required, please contact Pulse for availability.

11. The temperature of the component (ambient plus temperature rise) must be within

the stated operating temperature range.
