GUS-QS8A-01-2493-JB Description

The GUS-QS8A-01-2493-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 249K Ohm resistance value and a tight 5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power dissipation across a wide temperature range (70°C to 125°C derated, 125°C max). The ±100ppm/°C temperature coefficient enhances stability in fluctuating thermal environments, while the 100V maximum voltage rating supports robust operation in industrial and instrumentation systems.

GUS-QS8A-01-2493-JB Features

• Thin-Film Technology: Offers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for multi-channel signal conditioning.
• Compact QSOP Package: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) footprint saves board space in dense layouts.
• Gull Wing Termination: Ensures secure surface-mount (SMD) attachment with a 0.64mm terminal pitch for automated assembly.
• Wide Power Handling: 0.75W total (0.1W per resistor) balances performance and thermal management.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and test equipment where RoHS compliance is not critical.
