FAQ

What is the center-tap configuration of the secondary winding?

The secondary winding is center-tapped (CT), providing two equal halves of the 800-ohm impedance.

Is the transformer suitable for high-frequency audio applications?

The transformer operates up to 25 kHz, which covers standard audio frequencies but may not be suitable for ultrasonic or very high-frequency applications beyond this range.
