GUS-QS8B-01-3902-C Description

The GUS-QS8B-01-3902-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 39KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its reliability in high-density PCB designs.

GUS-QS8B-01-3902-C Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Gull Wing Termination: Ensures robust solder joints and compatibility with automated SMT processes.
• Derated Power Handling: Maintains performance up to 125°C with derated power (0.05W per resistor).
• BUS Circuit Designator: Optimized for bus line termination and pull-up/down applications.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use where PPAP compliance is not required.
