GUS-QS0B-03-9100-GA Description

The GUS-QS0B-03-9100-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 910Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it maintains stability across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical characteristics, while the gull-wing termination ensures reliable solder joints in automated assembly processes. Packaged in a tube for safe handling, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.

GUS-QS0B-03-9100-GA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), optimizing board space in dense layouts.
• 19 Resistors in BUS Configuration: Simplifies circuit design by reducing discrete component count.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power handling.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress.
• Gull-Wing SMD Termination: Ensures compatibility with reflow soldering and automated placement.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded finishes.
