GQCA035111BT Description

The GQCA035111BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 5.11KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in circuit performance. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, making it suitable for environments requiring thermal stability. Its ceramic case style and gull-wing termination provide robust mechanical and electrical reliability in surface-mount (SMD) applications. With a ±25ppm/°C temperature coefficient, it delivers minimal resistance drift, critical for precision analog and digital systems.
