+5.0V PULSE TRANSFORMERS
In selecting isolation transformers to be used with the SSRT
Mark3 +5.0V (BU-64703X3/4), there is a limitation on the maxi-
mum amount of leakage inductance. If this limit is exceeded, the
transmitter rise and fall times may increase, possibly causing the
bus amplitude to fall below the minimum level required by MIL-
STD-1553. In addition, an excessive leakage imbalance may
result in a transformer dynamic offset that exceeds 1553 specifi-
cations.
The maximum allowable leakage inductance is 6.0 H, and
is measured as follows:
The side of the transformer that connects to the SSRT Mark3
+5.0V (BU-64703X3/4) is defined as the “primary” winding. If one
side of the primary is shorted to the primary center-tap, the
inductance should be measured across the “secondary” (stub
side) winding. This inductance must be less than 6.0 H.
Similarly, if the other side of the primary is shorted to the prima-
ry center-tap, the inductance measured across the “secondary”
(stub side) winding must also be less than 6.0 H.
The difference between these two measurements is the
“differential” leakage inductance. This value must be less than
1.0 H.
Beta Transformer Technology Corporation (BTTC), a subsidiary
of DDC, manufactures transformers in a variety of mechanical
configurations with the required turns ratios of 1:2.5 direct cou-
pled, and 1:1.79 transformer coupled. TABLE 4A provides a list-
ing of many of these transformers.

TABLE 4A. BTTC TRANSFORMERS FOR USE WITH SSRT MARK3 +5.0V (BU-64703X3/4)
Notes:
1. For the BU-6XXXXX4 versions of the SSRT Mark3, which include the McAir-compatible transceivers, only the B-3818 or B-3819 transformers (shown in bold in
the table) may be used.
2. For the BU-6XXXXX3 versions of the SSRT Mark3 with -1553B transceivers, any of the transformers listed in the table may be used.
3. DLP-7115 operates to +85°C max. All other transformers listed operate to +130°C max.
The list of approved transformers for use with the SSRT Mark3 is constantly being updated. Please contact Beta Transformer Technology Corporation for the
latest transformer configuration information.
