Shielded Power Inductors – SLC1480
The SLC1480 is designed for high-speed switch mode
applications requiring low inductance and very high
saturation current ratings. While requiring a mere quar-
ter square inch of board space, it can handle current as
high as 130 A.
These shielded inductors are ideal for use in multi-phase
VRM/VRD regulators and high current/high frequency
DC/DC converters.

1. When ordering, please specify packaging code:
SLC1480-321MLD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
3. DCR is measured between the two points indicated below.
Points used for measuring DCR
4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
5. DC current at which the inductance drops from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
