GUS-QS0B-03-3740-JD Description

The GUS-QS0B-03-3740-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors with a 374Ω resistance value, offering a 5% tolerance and a ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs. Packaged in a tube, it is ideal for automated assembly processes.

GUS-QS0B-03-3740-JD Features

• Thin-Film Technology: Delivers superior stability, low noise, and tight tolerance (±25ppm/°C) for precision circuits.
• High-Density Integration: 19 resistors in a QSOP-20 package reduce board space and simplify routing.
• Robust Performance: 1W total power dissipation and 125°C maximum operating temperature ensure reliability in demanding environments.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch optimize pick-and-place efficiency.
• Wide Voltage Range: Supports up to 100V, making it suitable for mixed-signal and power distribution applications.
• Non-Automotive/Non-PPAP: Optimized for industrial and commercial use where PPAP compliance is not required.
