Amp-microsend (AµSec.) rating of primary equalts volt microsend (VµSec.) rating of secondary when secondary is terminated in rated resistance. (Amp - microsends is equal to the product of a square pulse of current in amps, times the current pulse width in microseconds. 4. When terminated with rated terminating resistance, the inductor scale factor is Vout = 1 volt per amp. for center tapped units terminating resistance for each half of winding is listed value divided by two. 5. 1 turn primary peak sense current is 20 amps for all parts listed above. 3. Maximum operating temperature 105 _°_ C (ambient plus rise).
