Primary

50mA DC current
Multi section winding, for reduced leakage inductance.

Inductance

Inductance 24H at 25Hz.
Leakage inductance 15mH

Bandwidth

Wide bandwidth, 20-30KHz. (-1dB)

Secondary

Output impedance 4,8 and 16 Ohms.

Steel

High quality Grain Orientated M6 0.35mm.
Hand laminated for the best stacking factor, and accuracy.

Winding wire
