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!
