1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (150 parts per full reel). Quantities less than
full reel available: in tape (not machine ready) or
with leader and trailer ($25 charge).
2. Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 1 and 3 with all other
pins shorted.
4. Output is for each secondary. Output of the aux winding is 10 V, 50 mA.
5. Based on 280 mT at 25°C and number of turns on pins 1-3.
6. Electrical specifications at 25°C.
