GUS-QS8B-02-1870-J Description

The GUS-QS8B-02-1870-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 187Ω resistance value and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). The network operates over a wide temperature range of 70°C to 125°C with a ±50ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMD processes.

GUS-QS8B-02-1870-J Features

• Thin-Film Technology: Offers superior stability, low noise, and tight TCR (±50ppm/°C) compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation circuits.
• Robust Power Handling: 0.05W per resistor (15 resistors) ensures balanced heat dissipation.
• BUS Circuit Designator: Optimized for bus termination, pull-up/pull-down, and voltage divider applications.
• Non-Automotive (PPAP No): Tailored for commercial and industrial use where PPAP compliance is not required.
