GQ0A031961GT Description

The GQ0A031961GT 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 integrates 10 isolated resistors, each with a 1.96KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in precision circuits. The ceramic case construction enhances thermal stability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a ±25ppm/°C temperature coefficient, it maintains stability across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. The 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) further underscore its robustness. Packaged in a tube, this non-automotive (PPAP: No) component is ideal for prototyping and low-to-medium volume production.
