GQ0A031181BT Description

The GQ0A031181BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.18 kΩ resistance value, 0.1% tolerance, and a ±25 ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and reliability in harsh environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for precision analog circuits where minimal drift and high accuracy are critical.

GQ0A031181BT Features

• High Precision: Tight 0.1% tolerance and low ±25 ppm/°C TCR ensure stable performance across temperature variations.
• Robust Construction: Ceramic case provides excellent thermal dissipation and mechanical durability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk, ideal for multi-channel systems.
• Surface-Mount Gull Wing Terminals: QSOP package with 0.64mm pitch enables compact PCB layouts.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive Grade: Optimized for non-PPAP industrial, medical, or test/measurement systems.
