GUS-QS8A-03-7500-FF Description

The GUS-QS8A-03-7500-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 750Ω resistance value per resistor with a tight 1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it ideal for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) attachment, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-03-7500-FF Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Compact & Robust: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) footprint with a 0.64mm terminal pitch for high-density layouts.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms standard networks in thermal management.
• Industrial-Grade Reliability: Non-automotive (PPAP No) but suited for industrial, telecom, and instrumentation use.
