Description and Applications
The military data bus specification, MIL-STD-1553, has brought about the
need for versatile pulse transformers that meet all the electrical requirements
of Manchester II serial bi-phase data transmission. The LPB-5000 series of
transformers provide the turns ratio configurations, component isolation, and
common mode rejection ratio characteristics necessary for MIL-STD-1553A
and B compliance.
The step-up and step-down ratios that are available with the LPB-5000 series
complement DDC’s entire MIL-STD-1553 product line and are compatible with
competitors’ drivers, receivers, and transceivers. These transformers are low-
profile, modular units that are multitapped to accommodate existing system
configurations. Encapsulated in accordance with MIL-PRF-21038, their C5191
Phosphor Bronze, Sn90 plated leads conveniently accommodate printed circuit
board mounting. Sinusoidal or trapezoidal waveforms are accurately pro-
cessed, making the LPB-5000 series of transformers an excellent choice for
any MIL-STD-1553A or B application.

Notes:
1) These transformers have been classified as IPC-9503 Level 1 and are not moisture sensitive. To ensure product integrity and maintain the product warranty, the reflow
process must not cause the peak body temperature of the device to exceed 225°C and must not expose the device to temperatures above 183°C for more than 90
seconds. Tape and Reel packaging is available upon request. Contact factory for further information.
