When ordering, please specify termination and packaging code: SER8052-103MED Termination: E = RoHS tin-silver over tin over nickel over phos bronze (pins 1 and 2); Matte tin over nickel over phos bronze (pin 3). Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C = 7 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 C instead. D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked(1000 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 8753D 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.
