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.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
Are flyback transformers dangerous?
Owing to (low) frequency and (high) current availability, MOTs are, in all cases, extremely dangerous... That said, the potential shock, even electrocution, hazards of
flyback (case in point LOPT) circuits should not be dismissed -
especially where resonant and/or current-mode drivers are employed!
