uPC 1181 / 1182 from NEC

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.

Absolute Maximum Ratings at 25 grdC.:

   Vcc1        :  25 V                 All information w/o guaratee!
Vcc2 : 18 V Only a hardly redable copy of Icc peak : 45 A of a japanese preliminary Pd : 12 W bis 115 grdC data sheet was available. Derating auf 0 W bei 150 grdC T operating : -30 to +75 grdC. T storage : -55 to 150 grdC.

Characteristics at Vcc=13.2V, 25 grdC.:

   Icc at Vin=0      typ 40 mA
   Po at T.H.D. = 10%, R Load = 4 Ohm : min 5 W, typ 5.8 W
   Po at T.H.D. = 10%, R Load = 2 Ohm :          typ 9.2 W

Case


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).
