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). **Irms Testing** I rms 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. ee 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. 4. DC current that causes a 20% (typ) inductance drop from its value without current.
