GQ0A032051CT Description

The GQ0A032051CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP-packaged device integrates 10 isolated resistors, each with a 2.05kΩ resistance and a tight ±0.25% tolerance, ensuring exceptional accuracy in circuit design. The ceramic case and gull-wing SMD termination provide robust mechanical stability and ease of surface mounting, while the ±25ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for precision analog and digital systems.
