Romoland, Calif. - The rugged 4260-1646 and 4260-1647 Series of data bus interface transformers from Datatronics Romoland, Inc. support high-speed data transmission requirements in a wide range of mission critical industrial and military applications.
The devices offer a minimum input impedance of 3,000 ohms or 7,200 ohms over the full temperature range of -55 degrees C to 130 degrees C. Designed to meet Mil-Std-1553 A/B and MAC AIR Specifications A-3818, A-5690, A-5232 and A-4905, the transformers offer high electrical performance while operating in harsh environments. They also meet MIL-PRF-21038, Grade 7, Class S, and is DESC approved as part numbers 82030-01 to -10.
Supporting a wide range of instrumentation, data collection and communications equipment, the transformers feature a frequency range (no load) of 75 KHz to 1 MHz. Other key specifications include an overshoot of 1-volt maximum, common mode rejection at 45 dB minimum, and droop at less than 20 percent.
Up to ten standard turns ratios are available with the Model 4260-1646 and 4260-1647 Series. They range 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 percent.
Model 4260-1646 and 4260-1647 devices, available in flat pack through-hole and surface-mount packages, are fully encapsulated to protect its circuitry. Available in both single and dual packages, the surface mount Model 4260-1646 and 4260-1647 devices feature a thin low profile of 6.35 mm (0.250 in) in a 12.7 mm (0.500 in) long by 8.89 mm (0.350 in) wide package.
Pricing for the 4260-1646 and 4260-1647 transformers starts at $17.00 each in quantities of 5,000, depending on configuration. OEM volume pricing is available upon request. Delivery is from stock to eight weeks.
