GUS-QS8A-00-12R4-GF Description

The GUS-QS8A-00-12R4-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 12.4Ω resistance per element with a tight 2% tolerance and a low ±250ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) with gull-wing SMD termination for reliable surface mounting. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this network is engineered for demanding circuits requiring isolation and precision.

GUS-QS8A-00-12R4-GF Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, eliminating crosstalk.
• Thin-Film Technology: Delivers superior accuracy, low noise, and stability.
• High Power Handling: 0.75W total (3/4W) with derated performance up to 125°C.
• Compact QSOP Package: Ideal for space-constrained PCBs with a 0.64mm terminal pitch.
• Robust Construction: Gull-wing leads enhance mechanical durability during assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications.
