1. When ordering, please specify termination and packaging codes:
DA2320-ALC
Termination: L = RoHS compliant tin-silver over tin over nickel over
phos bronze
Special order, added cost:
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
3. Leakage inductance measured at 100 kHz, 0.1 Vrms with secondary
pins shorted.
4. SRF measured with coils connected in series using an Agilent/HP
4192 or equivalent.
5. Operating temperature range −40°C to +125°C.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
