1. When ordering, please specify packaging code:
SLR1190-371KEC
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 (450 parts per
full reel).
2. Inductance at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR is measured on a micro-ohmmeter at points indicated in the
diagram below.

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.
4. DC current that causes a 20% (typ) inductance drop from its value
without current. Click for temperature derating information.
5. 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.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
