The MET-28-T-B is a miniature encapsulated transformer designed for data and voice coupling. It features a primary impedance of 1KΩ, a secondary impedance of 50Ω, and a turns ratio of 4.47:1. This transformer is rated for a 50 mW power level and can handle a maximum DC unbalance of 3.0 mA in the primary winding. With an operating temperature range of -20°C to 85°C and a dielectric strength of 500 VRMS, its epoxy-molded construction ensures durability. These characteristics make it suitable for high-reliability designs in demanding communication systems.
