STK404-050 Audio Power Amplifier IC

The STK404-000 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO’s unique insulated metal substrate technology (IMST). The adoption of a newly-
developed low thermal resistance substrate allows this series of devices to be provided in miniature packages significantly more compact than earlier Sanyo products with similar specifications.

Core parameters :

• Compatible power amplifiers ranging from 45 W to 180 W (10% per 1 kHz) devices.
• The STK404-050 comes in several miniature size:
• 30 Watt to 40 Watt (THD = 0.4%, f = 20 Hz to 20 kHz); 44.0 mm × 25.5 mm × 8.5 mm.
• 50 Watt to 80 Watt (THD = 0.4%, f = 20 Hz to 20 kHz); 46.6 mm × 25.5 mm × 8.5 mm.
• 100 Watt to 120 Watt (THD = 0.4%, f = 20 Hz to 20 kHz); 59.2 mm × 25.5 mm × 8.5 mm.
• Output load impedance: RL=6Ω
• Allowable load shorted time: 0.3 seconds.
