Audio Transformer 1 to 1 600:600 Ohm 4kV Line Isolation

This is one item of new 1:1 audio isolating transformer.

The data sheets are shown in the secondary pictures. D.C. current should be avoided in the windings. The headline specifications are as follows.

Headline Specs:

Primary D.C. Resistance: 65 Ohm +/-15%
Secondary D.C. Resistance: 65 Ohm +/-15%
Impedance Match: 600:600 Ohm
Inductance 10mV rms@200Hz: 4.15H min
Leakage Inductance: 20mH max
Insertion Loss: 1.3dB max
Frequency Response: 300Hz-4kHz +/-0.2dB
Distortion: -77dB max (0dB, 300Hz)
Saturation: 10Vrms
Isolation Voltage: 4kV for 1 minute

These typically find uses as hum loop breakers in long line analog audio situations or guitar applications. The headline -0.2dB bandwidth may not be particularly wide, but the -3dB bandwidth is substantially greater than this.
