MIL-STD-1553 TRANSFORMERS
QPL Interface Transformers Overview
QPL MIL-STD-1553 Interface Transformers
As “Technitrol Components Division,” we were the first
to achieve QPL status for MIL-STD-1553B interface
transformers, also known as low-power pulse
transformers. Today, as “Pulse Military Aerospace
Division,” our QPL transformer line includes a wide
selection of products for each of the product levels called
for by MIL-PRF-21038/27, formerly MIL-T-21038/27.
We also were the first to achieve QPL status on surface-
mount MIL-STD-1553 pulse transformers -- more than
20 years ago. To this day, many manufacturers have
MIL-PRF-21038E (8 July 1998) supersedes
MIL-T-21038D (11 May 1979) and establishes three
product levels for low power pulse transformers. The
new specification allows designers to select a QPL
device and limit the testing to what is needed for the
application:

difficulty producing components that can survive the
high-heat rigors of surface mounting and the
performance, reliabliability, part-to-part repeatibility, and
lifespan required by high-rel military and commercial
applications.
The first several pages of this catalog cover all of our
QPL transformer products. Each part has a military des-
ignation number (found on DESC/DSCC approved draw-
ings) as well as our own product number. These part
numbers are listed in the specification tables.
Level C parts are tested to our internal specifications.
Group A or B testing is not performed on Level C parts.
Level M parts is exactly the same as the original QPL
product that was defined by the earlier MIL-T-21038/27
specification. Level T part receives the most extensive
testing along with thermal cycling. For information about
testing to selected levels, see next page.
