GQ0A011151GT Description

The GQ0A011151GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package features 10 isolated resistors, each with a 1.15KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount assembly. With a power rating of 1W (0.1W per resistor) and a wide operating temperature range of -70°C to +125°C, this network is engineered for durability in harsh environments. Its ±100ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision analog and digital systems.
