• Tight DCR tolerance for inductor-DCR-based current

sensing circuits

• Excellent current handling, up to 93 A

• 10.4 × 8.0 × 7.4 mm surface mount package

• Designed for use in multi-phase VRM/VRD/EVRD regulators

1. When ordering, please specify

packaging code:

SLR1075-301KEC

Packaging:

C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (100 parts 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 (500 parts per

full reel).

2. Inductance at 100 kHz, 0.1 Vrms, 0 Adc.

3. DC current that causes an inductance drop of 20% (typ) from its value

without current.

4. Current that causes the specified temperature rise from 25°C ambient.

This information is for reference only and does not represent absolute

maximum ratings.

5. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Irms Testing

Irms testing was performed on 0.75 inch wide × 0.25 inch thick

copper traces in still air.

Temperature rise is highly dependent on many factors including

pcb land pattern, trace size, and proximity to other components.

Therefore temperature rise should be verified in application

conditions.
