Low Power Pulse Transformers — 2
As part of Pulse, Specialty Components has access
to offshore manufacturing, state-of-the-art packag-
ing technology and worldwide purchasing power to
provide extremely cost-effective products for cus-
tomers. Many low-power pulse transformer prod-
ucts have been developed in response to the Perry
Initiative and its COTs mandate.
The products shown on the next page and described
in this catalog have performance and electrical char-
acteristics compliant with MIL-PRF-21038/27 but
have been tailored in response to the demands of
today's marketplace....
nCOTs models for reduced-requirement
military applications (non-QPL) and reduced cost
nLow profile for reduced board-stacking height
nSingle- ratio and dual-ratio
nSingle interface and dual interface
nVertically stacked dual interface
n0-70OC or -40 to +85OC or -55 to +125OC
nHermetically sealed for extreme environments
