Schematic
1. When ordering, please specify termination and packaging codes:
DW3316-685MLD
Termination:L = Gold over nickel over phos bronze terminations
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 (750 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.
2. Inductance is per winding, tested at 10 kHz, 0.1 Vrms, 0 Adc using an
Agilent/HP 4263B LCR meter or equivalent.
3. SRF is measured using an Agilent/HP 8753D network analyzer.
4. DC current at which the inductance drops 10% (typ) from its value without current.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
