1. When ordering, please specify packaging code:
SLR1065-301KEC
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).
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.

Recommended Land Pattern
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.
