GUS-QS8A-01-3921-GG Description

The GUS-QS8A-01-3921-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 3.92KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports derated operation from 70°C to 125°C, making it suitable for environments with elevated thermal stress. The ±100ppm/°C temperature coefficient enhances stability across varying conditions, while the 100V maximum voltage rating ensures reliability in high-voltage applications.

GUS-QS8A-01-3921-GG Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog and digital circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, providing design flexibility.
• Robust Construction: QSOP package with gull-wing termination ensures secure surface-mount assembly (SMD) and mechanical durability.
• Wide Temperature Range: Operates reliably from -55°C to 125°C, with derated power up to 125°C.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained PCBs.
• Non-Automotive, Non-PPAP: Ideal for industrial, telecom, and instrumentation applications where automotive compliance is not required.
