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 Specialty Components,” 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 MILSTD- 1553 pulse transformers -- more than 15 years ago. To this day, many manufacturers have difficulty producing components that can survive the high-heat rigors of surface mounting and the performance, reliability, part-to-part repeatability, and lifespan required by high-rel military and commercial applications.
