DESCRIPTION AND APPLICATIONS
The military data bus specification, MIL-STD-1553, brought about the
need for versatile pulse transformers that meet all the electrical require-
ments of Manchester II serial bi-phase data transmission. The MLP-2000
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 MLP-2000
series complement DDC's entire MIL-STD-1553 product line. These
transformers are low-profile and provide a 70% reduction in board space
compared to surface mount QPL pulse transformers. They are encapsu-
lated and meet the performance requirements of MIL-PRF-21038.
Sinusoidal or trapezoidal waveforms are accurately processed, making
the MLP-2000 series of transformers an excellent choice for any MIL-
STD-1553A or B application.

Note:
1) These transformers have been classified as Level 5A per IPC-9503 and must be processed accordingly. To ensure product integrity and maintain the product warranty,
these transformers require a 24 hour bake at +125° C prior to any solder reflow processing. Dried transformers must be reflowed within 24 hours. These parts are pro-
vided dry-packed in accordance with J-STD-033. Tape and Reel packaging is available upon request. Contact factory for further information. 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.
2) By providing surface mount parts that have been dried per IPC-9503 (Moisture Sensitivity Classification for Non-IC components) and Dry-Packed in accordance with
J-STD-033 (Standard for handling, packing, shipping and use of Moisture/Reflow sensitive surface mount devices), Beta has significantly reduced the possibility of
moisture sensitivity/reflow induced "Pop-corning" or Bulging during customer's reflow soldering process. Experiments performed by Beta and data provided by manufac-
turers of similar devices indicate that post reflow visual/mechanical anomalies can be reduced by more than 90%. Since customer reflow profiles and CCA density can
vary, Beta recommends that the customer verify solder process compatibility and yield assessment of these devices.
3) The Lead-Free/RoHS compliant versions use Sn10Pb88Ag02 for internal solder joints. High melting temperature solder in excess of 85% lead is exempt until a suitable
alternative is available. The external lead finish is matte-tin with a nickel barrier layer that has been certified to pass JESD22A121.01 tin whisker limits. The magnet wire
used has a minimum Thermo-plastic Flow rating of 250°C. These transformers are classified as IPC-9503 level 5A. The peak body temperature shall not exceed 245°C,
and the time over 183°C shall not exceed 150 seconds. The Lead-Free/RoHS compliant part numbers are the standard part, with an "-R" as the part number suffix. The
bottom of the header has the Pb-free symbol embossed on it.
