GUS-QS0B-03-3830-J Description

The GUS-QS0B-03-3830-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 383Ω resistance value per resistor with a 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 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and supports 100V maximum voltage. Its thin-film technology provides superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.

GUS-QS0B-03-3830-J Features

• Precision Thin Film: Delivers tight tolerance (±5%) and low TCR (±25ppm/°C) for stable performance in varying conditions.
• High-Density Packaging: QSOP case (8.66mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch saves board space in dense layouts.
• Robust Power Handling: 1W total dissipation (1/20W per resistor) and 125°C max operating temperature suit demanding environments.
• Automated Assembly Friendly: Gull-wing leads enable reliable surface-mount soldering, while tube packaging simplifies pick-and-place processes.
• BUS Circuit Designator: Ideal for bus termination, pull-up/pull-down networks, and voltage division in digital systems.
