When order- ing, simply change the last letter of your part number from B to C. D = 13 machine-ready reel. EIA-481 em- bossed plastic tape. Factory order only, not stocked (700 parts per full reel) 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A test fixture. 5. DC current at 25C that causes the specified inductance drop from its value without current. Click for temperature derating information. 6. Current that causes the specified temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 7. Electrical specifications at 25C.
