1. When ordering, please specify version and packaging codes:
SLR1050C -221KEC
Version A = Lowest DCR; B = Balanced DCR / DCR tol;
C = Tightest DCR tolerance
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 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 (1000 parts
per full reel).
2. Inductance at 100 kHz, 0.1 Vrms, 0 Adc.
3. DC current at 25°C 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.
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.
