GQ8A011782BAT Description

The GQ8A011782BAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 17.8KΩ resistance value with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 16 gull-wing terminals for reliable surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for precision signal conditioning, voltage division, and impedance matching in critical circuits.

GQ8A011782BAT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for minimal drift in harsh environments.
• Robust Construction: Ceramic case ensures thermal stability and durability.
• Space-Efficient: Compact QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Design: Circuit designator "ISOL" indicates independent resistors, ideal for multi-channel isolation.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Reliable Termination: Gull-wing leads provide strong solder joints for automated assembly.
