1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (175 parts per full reel). Quantities less than fullreel available: in tape (not machine ready) or withleader and trailer ($25 charge).
2. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc.
3. Leakage inductance is for the primary with the secondary and auxwindings shorted.
4. DC current applied at the primary at 25°C that causes an inductancedrop of <10% from its value without current.
5. Output is for the secondary. Output of the aux winding is 12 V, 30 mA.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
