D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (700 per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284. Irms Testing 3. DCR is measured between the two points indicated below. 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.
