LL2811 Audio Output Transformer

LL2811 is an audio output transformer for balanced drive, with the following features:
1. Four section winding structure for small leakage inductance.
2. Ideally used 2 : 1 (secondaries in parallel) with e.g. NE5532 op amps for low noise.
3. Precision made audio C core for small size.
4. Two-coil structure and mu-metal housing for high magnetic noise immunity.
5. Designed to fit three in a row across a Euroboard.
The secondaries can be connected in parallel for low output impedance or in series for high output level.
