Shielded Power Inductors – SLC1175

Document 838-1

Document 838-1 Revised 09/15/15

• Ideal for use in multi-phase VRM/VRD regulators and high

current/high frequency DC/DC converters.

• Offersinductancevaluesunavailableinotherhighcurrentseries.

1. When ordering, please specify

packaging code:

SLC1175-301MEC

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (150 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.

D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape. Factory order only, not stocked (700 per full reel).

2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.

3. DCR is measured between the two points indicated below.
