GUS-QS8A-00-42R2-GF Description

The GUS-QS8A-00-42R2-GF is a high-performance 8-resistor thin film network from TT Electronics/IRC, designed for precision applications requiring stable resistance and thermal performance. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a 42.2Ω resistance per resistor with a tight 2% tolerance and a ±250ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.

GUS-QS8A-00-42R2-GF Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance (±250ppm/°C).
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained PCBs.
• High Power Handling: 0.75W total power rating (0.1W per resistor) ensures robustness in power-sensitive designs.
• Isolated Resistor Network: Reduces interference in multi-channel applications like sensor arrays or differential amplifiers.
• Wide Operating Range: Functions reliably from -70°C to +125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Gull-Wing Termination: Facilitates easy soldering and inspection in surface-mount assemblies.
