1. When ordering, please specify termination and packaging codes:
DA2320-ALC
Termination: L = RoHS compliant tin-silver over tin over nickel overphos 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). Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
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.
