Schematics
Termination: E = RoHS compliant tin-silver-copper over silver-plati-
num-glass frit.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2500 parts per
full reel).
2. Inductance measured per winding at 100 KHz, 0.1 V, 0 Adc on an
Agilent/HP 4192 or equivalent.
3. DCR measured per winding on a micro-ohmmeter.
4. Electrical specifications at 25°C.Measurements are referenced to 50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
