Not suitable for PCB-mounting.
Explanations:
–
tr rise time at given load resistor R and 70% of the output pulse height.
–
Lp primary inductance measured at 1kHz (secondary coile open).
–
Lstr stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils only one at the time is connected (measuring frequency 10kHz).
–
The ignition current is a set peak value where the voltage drop over the coil resistance is still insignificant (mostly below 1V).
