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.
