A187A14C microphone transformers from OEP are ideal for signal splitting and impedance matching. They are encapsulated in a mumetal can and constructed with multiple electrostatic screens. These audio transformers provide dual primary impedance for matching 150 Ω to 15 kΩ.
750 mH primary inductance at 1 kHz, 0.1v. 44 pF interwinding capacitance at 20 kHz (primary 1 to screens). 64 pF interwinding capacitance at 20 kHz (primary 2 to screens). 109 pF interwinding capacitance at 20khz (secondary to screens). 12 pF interwinding capacitance at 20 kHz (primaries to secondary when primaries are in series)
Primary Impedance = 150 Ohms, 600 Ohms
Secondary Impedance = 10kOhms
Primary DC Resistance = 38Ohms
Secondary DC Resistance = 1.085kOhms
Dimensions = 29.4 x 25 x 24.2mm
Mounting Type = Through Hole
Termination Type = PC Pin
Weight = 56g
Depth = 24.2mm
Length = 29.4mm
