A187A17C and A187A18C microphone transformers from OEP are ideal for impedance matching and signal splitting. Constructed with multiple electrostatic screens, these audio transformers are encapsulated in a mumetal screening can. A187A17C can be used in microphone inputs, matching 200 Ω to 600 Ω, while A187A18C can be used to match 200 Ω to 5 k Ω. 500 Vrms proof voltage, windings to screen. 500 Vrms proof voltage, primary to secondary. Screens earthed Primary Impedance = 200Ohms Secondary Impedance = 5kOhms Primary DC Resistance = 13.5Ohms Secondary DC Resistance = 352Ohms Dimensions = 29.4 x 25 x 24.2mm Mounting Type = Through Hole Termination Type = PC Pin Weight = 56g Depth = 24.2mm Length = 29.4mm
