GUS-QS8A-01-4301-GA Description

The GUS-QS8A-01-4301-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.3K Ohm resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70 to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and robust 0.75W (3/4W) total power rating, making it ideal for space-constrained designs.

GUS-QS8A-01-4301-GA Features

• High Precision: Thin-film technology delivers low TCR (±100ppm/°C) and 2% tolerance for reliable signal conditioning.
• Robust Power Handling: 0.1W per resistor (0.75W total) with a 100V maximum voltage rating, suitable for demanding circuits.
• Compact & Durable: QSOP package with gull-wing leads ensures mechanical stability and ease of automated assembly.
• Wide Operating Range: Stable performance from -55°C to +125°C (derated above 70°C), ideal for industrial environments.
• Isolated Design: Circuit designator "ISOL" provides electrical isolation between resistors, reducing crosstalk.
