GQ0A031780DT Description

The GQ0A031780DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP ceramic-packaged device integrates 10 isolated resistors, each with a 178 Ω resistance value and a tight ±0.5% tolerance. Its thin-film technology ensures excellent stability with a low ±25 ppm/°C temperature coefficient, making it ideal for precision analog and digital circuits. The network operates over a wide temperature range (-70°C to +125°C) and supports a maximum voltage rating of 100V, with a 1W total power dissipation (0.1W per resistor). The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical reliability.
