GUS-QS8A-03-78R7-JD Description

The GUS-QS8A-03-78R7-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 78.7Ω resistance value with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. Each resistor delivers 0.1W (1/10W) power dissipation, with a total power rating of 0.75W (3/4W). The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-03-78R7-JD Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High Power Density: 0.75W total power in a miniaturized QSOP package outperforms similar arrays in thermal management.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated up to 125°C), suited for industrial environments.
• Robust Construction: Gull-wing leads and 100V rating ensure mechanical and electrical resilience.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use, avoiding unnecessary automotive-grade cost premiums.

GUS-QS8A-03-78R7-JD Applications

• Signal Conditioning: Ideal for ADC/DAC reference dividers and sensor interfaces due to low TCR (±25ppm/°C).
