The MMT-3000 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 MMT-3000 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 encapsulated and meet the performance requirements of MIL-PRF-21038. Sinusoidal or trapezoidal waveforms are accurately processed, making the MMT-3000 series of transformers an excellent choice for any MILSTD-1553A or B application. * Surface Mount -Tape and Reel Available * For Use with MIL-STD-1553A and B, MacAir A-5690, A-5232, and A-4905 * Withstands conventional IR/Convection Reflow Process * Low Profile * -55C to +130C Operating Temperature Range * Built and Tested to MIL-PRF-21038 and MIL-STD-202 N:1 OVERSHOOT AND RINGING 1 V MAX E IN ED E OUT 90% EOUT tr E IN = 10 V rms at 1 MHz E Calc: CMR = 20 log IN (see note) E OUT tf FIGURE 2.

To ensure product integrity and maintain the product warranty, these transformers require a 24 hour bake at +125C prior to any solder reflow processing. Dried transformers must be reflowed within 24 hours. J-STD-033 preconditioning (drypack) can be provided by Beta upon request. Reflow process must not cause the peak body temperature of the device to exceed 225C and must not expose the device to temperatures above 183C for more than 90 seconds. 2 BETA TRANSFORMER TECHNOLOGY CORP * 40 ORVILLE DRIVE * BOHEMIA NY 11716-2529 * 631-244-7393 * FAX 631-244-8893 TAPE AND REEL MECHANICAL OUTLINE 0.059 +.004/-.000 ( 1.5 +.1/-.0) 0.079 (2.00) 0.012 .002 (0.30 .05) 0.157 (4.00) 0.069 (1.75) R 0.012 MAX (R 0.30 MAX) 0.453 (11.50) 0.46 (11.7) 0.28 (7.1) 0.94 .012 (24.0 .3) 0.42 (10.7) 0.059 MIN ( 1.50 MIN) 0.787 (20.00) R 0.02 TYP (R 0.5 TYP) 0.54 (13.7) 0.58 (14.7) DMENSIONS ARE IN INCHES (MM) TOLERANCES .XX (.X) = .008 (0.20) .XXX (.XX) = .004 (0.10) PARTS PACKAGED ON 13" DIAMETER REEL, 400 PARTS PER FULL REEL. 3 The information in this data sheet is believed to be accurate; however, no responsibility is assumed by Beta Transformer Technology Corporation for its use, and no license or rights are granted by implication or otherwise in connection therewith.
