When ordering, specify termination code: SER2915-333KL Termination:L=RoHS compliant tin-silver over copper. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). 2. Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. 3. DCR measured on a Keithley 580 microohmmeter or equivalent. 4. SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16092A test fixture. 5. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. When Isat rating is less than Irms, Isat is the more critical specification. 6. 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. When Irms is greater than Isat, Isat is the more critical specification, and Irms is shown in gray type. See Temperature Rise vs Current curve on next page. 7. Electrical specifications at 25°C.
