Data Bus Transformer Eyes Military Apps

With a minimum input impedance of 3,000W or 7,200W over the full temperature range of up to -55°C to +130°C, the 4260-1646 and 4260-1647 Series Data Bus Interface Transformers support high-speed data transmission requirements in a wide range of mission critical industrial and military applications. Designed to meet Mil-Std-1553 A/B and MAC AIR Specifications A-3818, A-5690, A-5232 and A-4905, the transformers feature a frequency range (no load) of 75 kHz to 1 MHz. Other key specifications include: overshoot of 1V maximum, common mode rejection at 45 dB minimum, and droop at less than 20%. The Series also meets MIL-PRF-21038, Grade 7, Class S, and is DESC approved as part numbers 82030-01 through 10. Up to 10 standard turns ratios are available for both models, ranging from a 1:1 turns ratio (primary 1-3, secondary 4-8) to a turns ratio of 3.2:1 (primary 5-7, secondary 1-3). Turns ratio accuracy is within ±3%. Available in both flat pack through-hole and compact surface mount packages, the Model 4260-1646 and 4260-1647 Series are fully encap- sulated to protect their circuitry. The surface mount models feature a low profile of only 6.35 mm in a package measuring 12.7 mm long by 8.89 mm wide. Pricing begins at $17.00 each/5,000. DATATRONICS ROMOLAND INC., Romoland, CA.
