## **– 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 quarter 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
