GUS-QS8A-03-1780-DD Description

The GUS-QS8A-03-1780-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 178Ω resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated assembly processes.

GUS-QS8A-03-1780-DD Features

• Precision Thin-Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25ppm/°C) for stable signal conditioning.
• High Power Handling: 0.75W total power rating (0.1W per resistor) with derating up to 125°C.
• Compact & Robust: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package saves board space while supporting 100V maximum voltage.
• Isolated Network (ISOL): Each resistor is electrically isolated, ideal for multi-channel applications.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch ensure compatibility with pick-and-place and reflow soldering.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation use.
