OEP A187A17C/A187A18C Microphone Transformers
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
Do not pass DC through the windings.
