1. When ordering, please specify packaging code:
SLR1075-301KEC
Packaging:
C = 7â³ 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 = 13â³ 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 âSoldering Surface Mount Componentsâ before soldering.
Irms Testing
Irms testing was performed on 0.75 inch wide à 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.
