DROOP:
20% max.
OVERSHOOT:
1V peak.
COMMON MODE REJECTION (CMR):
Greater than 45dB.
DIELECTRIC STRENGTH:
All units tested at 200 V RMS.
INSULATION RESISTANCE:
Greater than 10,000 Megohms at 300 V DC.
WEIGHT:
4 Grams.
OPERATING TEMPERATURE:

TERMINALS:
Solid .012 Diameter Conductor. Solderability per MIL-STD-202, Method 208.
These pulse transformers manufactured to MIL-STD-1553 COMMAND/RESPONSE
MULTIPLEX DATA BUS requirements. They also are manufactured to MIL-PRF-21038
specifications and are designed to meet MAC AIR SPECIFICATIONS A3818, A5690, A5232
and A4905.
All of these transformers exhibit superior electrical performance. Common mode rejection ratio
is greater than 45dB at 1 MHz. Input impedance is greater than 3000 ohms over the band from
75 kHz to 1 MHz at 1V rms. This series possesses exceptional waveform integrity: Rise time
and fall time is less than 100 nanoseconds. Overshoot and ringing is less than ±1V peak. Droop
is less than 20%.
