The objective of this product advisory is to inform MIL-STD-1553 circuit designers of lessons learned during a residual voltage investigation and to offer some transformer selection recommendations to minimize residual voltage.
This amendment adds BTTC as an approved transformer supplier for optimal compatibility with the Cobham 1553 Transceiver. The results of the BTTC compatibility study are included. A final recommendation for leakage inductance screening limits is defined.
