GQ8A021180GT Description

The GQ8A021180GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 8-resistor isolated network features a 118Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust performance in compact designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.

GQ8A021180GT Features

• Precision Thin Film Technology: Delivers stable resistance with ±50ppm/°C TCR for minimal drift under thermal stress.
• High Power Handling: 0.75W total power rating (0.1W per resistor) ensures reliability in power-sensitive circuits.
• Isolated Network (ISOL): Each resistor operates independently, ideal for multi-channel signal conditioning.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical robustness compared to plastic alternatives.
• Wide Operating Range: Functions reliably from -70°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP-certified).
• Low Profile: 1.47mm height and 4.9mm × 6.02mm footprint save space in high-density PCB layouts.
• 100V Maximum Voltage Rating: Supports moderate-voltage applications without degradation.
