GUS-QS8A-03-1202-JA Description

The GUS-QS8A-03-1202-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 12K Ohm resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal performance. The ±25ppm/°C temperature coefficient guarantees stability in fluctuating environments, while the 100V maximum voltage rating enhances durability. Packaged in a tube for automated assembly, its gull-wing termination ensures secure PCB mounting.

GUS-QS8A-03-1202-JA Features

• Isolated Circuit Design (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in sensitive circuits.
• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), ideal for space-constrained designs.
• High Power Handling: 0.75W total dissipation with 0.1W per resistor, outperforming similar networks in power density.
• Stable Performance: ±25ppm/°C TCR ensures minimal resistance drift under thermal stress.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch simplify pick-and-place assembly.
