1. When ordering, please specify packaging code:

SLR1070-301KEC

Irms Testing

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

copper traces in still air.

Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic

tape (150 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 (800 parts per

full reel).

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.

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.

Click for temperature derating information.

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. Click for temperature derating information.

5. Electrical speciﬁcations at 25°C.

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