*MIL-PRF-21038E (8 July 1998) supersedes
MIL-T-21038D (11 May 1979) and establishes
three product levels for low power pulse transformers:
nLevel C - for high reliability
commercial/industrial applications;
nLevel M - for general purpose
military applications;
nLevel T - for high reliability
critical military applications.
nqualified for use in QPL MIL-STD-1553 applications
ndual ratio in a single package, see schematic
