GUS-QS8A-03-88R7-DC Description

The GUS-QS8A-03-88R7-DC from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package, it features an 88.7 Ω resistance per resistor with a tight 0.5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. With a 100V maximum voltage rating and gull-wing termination, this RoHS non-compliant network is ideal for industrial and instrumentation applications requiring precision and reliability.

GUS-QS8A-03-88R7-DC Features

• Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25 ppm/°C) for stable performance.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, saving PCB space.
• Isolated Resistors: Independent 88.7 Ω resistors enable flexible circuit design without shared connections.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) supports robust operation.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its performance parallels higher-tier models.
