1. When ordering, please specify a packaging code:
GA3550-BLD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 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 D instead.
2. Inductance is for each winding, measured at 200 kHz, 0.4 Vrms, 0 Adc.
3. Leakage inductance is measured at 200 kHz, 0.4 Vrms with secondary
pins shorted.
4. Volt-time product is per winding.
5. SRF is per winding, measured on an Agilent/HP 4192 or equivalent.
6. Operating temperature range −40°C to +85°C.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
