Termination:L =RoHS compliant gold over nickel over phos bronze. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging:D =13″ 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 D instead. 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. Tolerances in bold are stocked for immediate shipment. 4. SRF >13 MHz measured using Agilent/HP 8753D network analyzer; <13 MHz using Agilent/HP 4192A. 5. DC current at which inductance drops the specified amount from its value without current. 6. Current that causes a 40°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
