5,8 W NF- Amplifier in Single In
Line Case
Specialties: Protections against short, over temperature, over voltage and surge protection. De-coupled input amplifier. Plastic case with metal back to be fixed on heat sink. 1181 and 1182 have mirrored pin connections to easily build symetric PCB circuits for stereo amplifiers.

Suggestions
Power
dissipation at 25 grdC. :
1. With heat sink (metal plate 100mm x 100mm x 2mm, Rth=12grdC./W :
10.5 W
2. With heat sink (metal plate 60mm x 60mm x 2
mm, Rth=16grdC./W : 7.5 W
Frequency response: Linear to 20 kHz,
Gain decrease 54 dB to 45 dB bei 100 kHz ( Po = 0.5 W).
