GUS-QS0B-03-4300-FD Description

The GUS-QS0B-03-4300-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 430Ω resistance value per resistor with a tight 1% 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 a maximum voltage rating of 100V. Its thin-film technology provides superior accuracy, low noise, and excellent long-term stability compared to thick-film alternatives.

GUS-QS0B-03-4300-FD Features

• Precision Thin Film: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for critical circuits.
• Robust Construction: QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch enables high-density PCB layouts.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• High Power Density: 1W total dissipation (distributed across 19 resistors) suits power-sensitive designs.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its performance parallels higher-tier industrial/research applications.
• Non-RoHS Compliant: Ideal for legacy or exempted systems requiring leaded components.
