GUS-QS8A-03-4221-GA Description

The GUS-QS8A-03-4221-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.22KΩ resistance value with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) ideal for space-constrained designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with precision.

GUS-QS8A-03-4221-GA Features

• Thin-Film Technology: Delivers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High Power Density: 0.1W per resistor (total 0.75W) in a miniature QSOP package, optimizing thermal management.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power), suitable for harsh environments.
• Robust Construction: Gull-wing terminals with 0.64mm pitch ensure secure surface-mount assembly and mechanical durability.
• Non-Automotive/Non-PPAP: Ideal for industrial, medical, and instrumentation applications where PPAP compliance is not required.
