GQ0A011911BAT Description

The GQ0A011911BAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.91KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±100ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. Packaged in a tube, this non-automotive (PPAP: No) component is ideal for industrial and instrumentation use.

GQ0A011911BAT Features

• Precision Resistance: 1.91KΩ ±0.1% tolerance for critical analog applications.
• High Power Handling: 1W total power (0.1W per resistor) with derating up to 125°C.
• Stable Thin-Film Technology: Low TCR (±100ppm/°C) ensures minimal drift over temperature.
• Robust Construction: Ceramic substrate and QSOP package offer superior thermal dissipation and mechanical durability.
