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
Core material Ferrite
Terminations RoHS compliant matte tin over nickel over copper.
Other terminations available at additional cost.
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
Weight 5.25 g
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.
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
Tape and reel packaging: –40°C to +80°C
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
3. DCR is measured between the two points indicated below.
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Points used for measuring DCR
Packaging 500/13″ reel; Plastic tape: 24 mm wide, 0.4 mm thick,
16 mm pocket spacing, 8.1 mm pocket depth
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.
PCB washing Only pure water or alcohol recommended
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
