1. When ordering, please specify termination and packaging codes:
GA3250-BLC
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
E = Halogen free component. RoHS compliant silver-
palladium-platinum-glass frit terminations.
Special order, added cost:
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 (1000 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 (3500 parts per
full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4284A LCR meter or equivalent.
3. DC current at which the inductance of L1 drops 20% (typ) from its value
without current.
4. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
