Availability: 570 In Stock
4-Stub Compact Coupler - 90-50204 This is a 4-stub, 2 bus jack, standard box style data bus coupler. The transformer ratio is 1.41:1 with R1-R2 stub resistor values of 59 ohm, 2W, 1%, the most common type. The bus coupler is connected between MIL-STD-1553B bus and bus devices (controllers, monitors and terminals). The purpose of a bus coupler is to reduce reflections, protect the bus and maintain impedance of the bus by employing a transformer and a pair of fault-isolation resistors.
