GQCA027500BBT Description

The GQCA027500BBT 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 750Ω resistors with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications in harsh environments. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits requiring tight resistance matching and minimal drift.
