When ordering, please specify termination code: SER2211-473MED Termination: E = RoHS compliant matte-tin over nickel over phos bronze. Special order: Q = RoHS tin-silver-copper over copper (95.5/4/0.5) or P = non-RoHS tin-lead (63/37). Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). 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 4391A impedance analyzer and an Agilent/HP 16193A test fixture. 5. DC current at which the inductance drops the specified from its value without current. Click for temperature derating information. 6. Current that causes a 40C 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. Refer to Doc 362 Soldering Surface Mount Components before soldering.
