GUS-QS8B-01-4121-GF Description

The GUS-QS8B-01-4121-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 4.12KΩ resistance value and a tight 2% tolerance, ensuring consistent performance across batches. The network operates within a wide temperature range of 70°C to 125°C (derated) and can withstand maximum temperatures up to 125°C, making it suitable for environments with thermal stress. Its thin-film technology provides excellent stability, low noise, and a ±100ppm/°C temperature coefficient, critical for analog and signal conditioning circuits.

GUS-QS8B-01-4121-GF Features

• High Power Handling: Delivers 0.75W (3/4W) total power (0.05W per resistor), ideal for power-sensitive designs.
• Precision Engineering: ±0.1mm length/height tolerances and ±0.2mm depth tolerance ensure reliable PCB mounting.
• Robust Construction: Gull-wing termination and surface-mount (SMD) design enhance mechanical durability and solderability.
• Voltage Resilience: Supports up to 100V, suitable for industrial and automotive (non-Automotive PPAP) applications.
• Compact Form Factor: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H), saving board space in dense layouts.
• Non-RoHS Compliant: For legacy systems requiring specific material compositions.
