A super quiet EP13 size flyback transformer. Primary inductance is 4.31mH +/- 10%. Switching frequency is 60 KHz minimum. The input is rated at 120V. There are 2 outputs rated at 2.5V/600mA and an aux rated at 17V/20mA. The power rating is 3.4VA, but it could handle twice that at 6.8VA. The design reduces electrical noise interference greatly by utilizing both an evenly wound dead winding and a fully cuffed copper shield around the core’s perimeter. High dielectric Kapton taping in sufficient layers after every winding ensures a 2500VAC hipot test is met.
